Short answer: the AGM Rattler V2 25-256 is the best thermal scope for hog hunting for most people in 2026, because hog work happens at 75 to 200 yards in groups, not at the 2,000 yards the spec sheets brag about. If your setup is a known feeder, you want a low base magnification and a wide field of view. If you are covering open agricultural land, you want reach and a laser rangefinder. If your rifle is an AR and every ounce on the front end matters, weight becomes the deciding factor.
Our team put ten thermal riflescopes through the same decision framework, reading published specifications, owner review patterns and the recurring complaints hunters post about each model. What came out the other end is a list that starts from how wild hogs actually behave rather than from a spec sheet ranking.
That distinction matters more than it sounds. A scope with a 2,000 yard detection range is a marketing number measured against a six-foot-tall human-shaped object on a clear day. Hogs are shot at feeders, along creek bottoms and in brush within a few hundred yards, usually in groups, usually while they are moving. The scope that keeps a whole sounder inside the picture beats the scope that resolves a distant fence post.
If you are still building out the rest of your kit, our picks for rifle scopes for deer hunting and crossbow scopes for accuracy cover the daytime side of the equation, while this guide stays on the thermal end.

1. AGM Rattler V2 25-256 – the best all-round hog thermal
AGM Global Vision Rattler V2 25-256 Thermal Scope High-Sensitivity Sensor
256x192 12um sensor
25mm lens, 3.5x base
11.5 hr runtime
IP67, 6.34 oz
Pros
- Clear image at feeder and close-medium range
- Two rechargeable batteries included with up to 11.5 hours runtime
- Quick-detach mount that returns to zero
- Works as a handheld monocular off the rifle
Cons
- 3.5x base is narrower than ideal for wide sounder work
- No daylight mode so the rifle is thermal-only
- Menus take real practice to learn
The Rattler V2 25-256 is the scope we keep coming back to for hogs because it gets the two things that matter most for group work right: a light 25mm objective that keeps a broad picture, and a removable battery system that survives a full sit without a power bank. At 6.34 ounces it is lighter than most of the dedicated thermal scopes in this list by a wide margin, which matters when the rifle is on an AR.
Florida and Texas owners in the review data report taking hogs at 10 to 50 yards and picking up boars past 200 yards, which lines up with how most people actually hunt hogs. The 3.5x base magnification is the one real compromise, and it is a fair trade for the 11.5 hour runtime and the sealed housing.
Reviewers repeatedly single out the quick-detach mount as the reason their zero survives moving the optic between rifles, which is a real problem on a multi-gun hog setup. The same owners cite the menu system as the roughest edge, so budget an evening with the manual before your first sit.

The stadiametric rangefinder is a rough distance estimate rather than a laser measurement, but at a known feeder that is all you need. Shot-activated recording with audio and built-in WiFi let you confirm shot placement and pull up footage without extra gear, which saves a trip in the dark.
One thing to understand before you buy: this is a thermal-only optic. It will not duplicate as a daylight scope, so if you want one rifle for daytime deer and nighttime hogs, you are looking at a clip-on instead. Owners who wanted that flexibility are the ones who regret the purchase, and it is the single most common complaint pattern we found.
IP67 sealing and a -22F operating rating mean a wet December sit in the woods is not a problem for this scope. The included case is not waterproof, so keep the scope in a dry bag rather than relying on the box.

Who the AGM Rattler V2 25-256 fits
This is the scope for a hunter who runs a feeder on a small property, works from a blind or treestand, and wants one optic that is light enough for an AR and sealed enough for rain. The 25mm objective gives a 37 degree field of view per the listing, wide enough to hold several pigs in a clearing at once, and the 3.5x base keeps them all readable without digital zoom.
It also works for mixed duty because it detaches from the rifle and scans as a handheld unit while you walk to a stand or check a fence line. Several owners in the review data treat it that way rather than carrying a separate monocular.
Where it falls short
The 3.5x base is the weak point for large sounders in open ground. If you routinely watch groups of eight or more pigs spread across a wide clearing, a scope starting at 1.5x or 2x gives you a meaningfully better first look, and you may end up zooming the Rattler digitally, which softens the picture.
Second, the 256×192 sensor cannot resolve fine detail. You will identify a hog without hesitation, but you will not pick out features or read a brand on a distant animal. For hog hunting at 100 to 150 yards, that limitation rarely comes up. For identifying a specific boar at 400 yards in a field, it does.
The menu is genuinely clunky by modern standards. Hunters in the buying discussions describe fumbling with the interface while an animal is moving, which is exactly when you do not want it. Learn the controls on the bench before you rely on them in the field.
2. AGM Rattler TS25-384 – the sharpest picture at feeder range
AGM Global Vision Rattler TS25-384 Thermal Imaging Riflescope for Hunting – Waterproof, Shockproof, Heat vison Thermal Scope with Adjustable Color Palettes, 8X Digital Zoom, 25mm Lens.
384x288 sensor
1024x768 OLED
1.5x base magnification
4.5 hr on CR123
Pros
- Very clear image on a large OLED screen
- Compact and light at 16 ounces
- Multiple palettes
- Scans well as a handheld unit
Cons
- Only 4.5 hours on CR123 batteries
- Digital zoom blurs the scene
The TS25-384 steps up from the 256 model where it counts for close work: a 384×288 detector driving a 1024×768 OLED, which is the sharpest screen-to-sensor pairing at this weight in the whole list. At 16 ounces it still mounts comfortably on an AR, and the 1.5x base magnification is the widest starting point among the dedicated scopes here.
That 1.5x base is the feature that makes this the right pick for a hunter who sits on a feeder and watches pigs work their way out of timber. You are not zooming to see a group. You are seeing a group from the moment the first one appears at the edge of the clearing.
Several owners in the review data call out hog and predator control as the exact use case, and the most common recommendation from experienced buyers is to step up from the cheaper 256 variant to this one for the sharper screen.

The trade-off is power. Up to 4.5 hours of continuous operation on two CR123 batteries is the weakest runtime in the field here, and cold nights shorten that further. If you plan to sit past midnight without a break, budget either a USB-C power bank, which the scope supports, or a rotation of cells.
Eight times digital zoom blurs the scene, so treat it as a way to confirm a distant shape rather than a way to identify one. The 25mm objective is narrower than the 35mm options on the market, so at 300 yards you are working inside a tight field of view.
It scans well as a handheld, which owners like for walking to a stand or following a wounded hog. IPX-class sealing is not specified beyond waterproof and shockproof in the listing, so keep it out of sustained downpours if you can.

What to check before buying this one
The most important check is battery planning, not optics. Four and a half hours covers a typical evening sit but not an all-night one, and CR123 cells lose capacity in cold weather. A small external battery pack is the single accessory worth adding to this purchase.
Second, confirm the scope fits your rail. It uses an integral mount rather than standard rings, which is convenient but locks you into whatever mount geometry AGM supplied.
Third, decide honestly whether you hunt close. If your realistic engagement distance is under 100 yards, this 1.5x base and this screen are close to ideal. If you regularly shoot past 300 yards, the narrow 25mm field of view will feel restrictive and you should look at a 35mm objective instead.
Where the TS25-384 is not the answer
The 4.5 hour runtime is the deal breaker for all-night sits, and there is no way around it. Hogs are active from dusk through the night, so a scope that forces a mid-sit break is worse than a heavier scope that never quits.
Digital zoom quality is the second limit. Pushing to 8x gives you a soft, blocky image, and the picture in the center can smear. If you plan to identify animals at distance rather than detect them, this is not the scope.
Finally, the listed eye relief figure of 45 millimeters and the compact housing mean you get a shorter eye box than a full-size tube scope. Glasses wearers should test it before committing to a long sit.
3. Pulsar Thermion 2 LRF 50mm – the open-field reach pick
Pulsar Thermion 2 XP50 Pro Thermal Riflescope with Rangefinder
640x480 17um sensor
NETD under 25mK
F50/1.0 lens
Built-in LRF, 12.8 oz
Pros
- Excellent thermal sensitivity in rain
- fog and cold mornings
- Built-in laser rangefinder adds ranging without extra gear
- IPX7 sealed magnesium alloy body
Cons
- Fixed 50mm lens gives a narrow close-range view
- Only 20 ratings so long-term data is thin
When your hog work spans a big open pasture rather than a feeder, the Thermion 2 LRF 50mm is the tool for the job. A 640×480 17um sensor at under 25 mK NETD behind an f/1.0 50mm lens is the most sensitive thermal setup in this group, and sensitivity is what carries you through fog, cold rain and a dawn hunt when a hog is standing in wet grass.
Detection range is quoted at up to 2,000 yards on a six-foot object. Treat that as a ceiling, not an expectation. For a hog-sized target in real cover, you are working inside a much shorter distance, but the sensitivity behind that number is genuinely what you are paying for.
At 12.8 ounces this is one of the lighter premium thermals, and the magnesium alloy body carries an IPX7 rating. Picture-in-picture zeroing, video recording and the Stream Vision 2 app cover the feature set that longer-range hunters expect.
The honest caveat on this pick is evidence. Review volume on this listing is thin, and the ratings skew heavily toward five stars without much written detail. Owners describe outstanding low-light sensitivity and identification in fog and rain, but the sample is too small to treat the performance claims as extensively validated.
How this scope behaves in real hog country
The 50mm f/1.0 lens is a light-gathering lens first and a wide-view lens second. At base magnification you will see a lot of landscape and a smaller animal, which is exactly what you want when pigs are 400 yards out in a pasture. As they close to 150 yards, you will want to come down in magnification, and a 2x base makes that easier than a 4x or 5x start would.
The built-in laser rangefinder is the practical differentiator here. If you do not know the distance to the treeline because you moved blinds, a rangefinder plus a ballistic solution replaces the guesswork that costs you shots. Picture-in-picture gives you a magnified aiming frame inside the wide scene for precise zeroing.
Where the Thermion 2 LRF is wrong for you
Do not buy this for feeder work or close brush. A 50mm objective is the wrong end of the trade for a 75-yard sitting, and the narrow field of view will make you work to keep pigs in frame when a group starts moving. It is a distance optic being asked to do a close-range job.
Second, the menu-driven interface takes time to learn, and the recalibration click that interrupts the image can be distracting when an animal is moving toward you. Neither is a deal breaker, but both reward a bench session before the hunt.
Third, be aware of what a thin review history means for resale and long-term support decisions. A scope you cannot find other owners talking about is a scope you are buying on faith in the specification set. That is a reasonable position, but it should be a conscious one.
4. AGM Adder 35-384 – the battery that outlasts the night
AGM Global Vision Adder 35-384 Thermal Imaging Riflescope for Hunting
384x288 12um sensor
35mm lens, 7.5 by 5.6 degrees
Up to 15 hour runtime
IP67, 2 lb
Pros
- Clear imagery with a broad field of view
- Battery runtime well ahead of the Rattler line
- Menus easier to navigate than competing apps
- 30mm quick-detach mount included
Cons
- Integral mount base may not clamp firmly
- Power button hard to locate in the dark
The Adder 35-384 solves the two problems that hurt most in a feeder setup: a wide field of view and a battery that survives the whole night. Two internal rechargeable batteries give up to 15 hours of runtime, which is the longest figure anywhere in this roundup, and the 35mm lens produces a 7.5 by 5.6 degree field of view that holds a sounder comfortably.
Hog hunters running this scope report clear imagery and standout battery endurance relative to AGM’s own Rattler line, with several taking boars at 200 yards. That combination of width and endurance is rare at this weight class.
The 384×288 12um sensor sits in the middle of the resolution tiers, sharp enough to identify a hog at feeder range without paying for a 640 body. Three-times to 24-times digital magnification covers the middle distances, and shot-activated recording and stadiametric ranging are both included.

The 4.1 rating needs context. The average is pulled down by a cluster of warranty and fulfillment complaints, including units arriving with shadow-image defects and being sent a substitute model, rather than by image quality complaints. Mount hardware fit and button usability are the most repeated gripes in the written feedback.
Two pounds is heavier than most of the scopes here, and on an AR that weight sits forward of the wrist. The included 30mm quick-detach mount is a genuine bonus, since you will otherwise need to buy rings separately, but some owners report the integral base does not tighten as firmly as two-piece rings and switched to rings for a firmer hold.
Firmware updates are now handled wirelessly through the AGM Connect app rather than over a cable, which improved an old complaint, and the app itself is well regarded for remote viewing.

Why the battery figure changes the hunt
Fifteen hours means a full night and a dawn sit on one charge, in any of the reasonable weather you are likely to be out in. For a hunter running an all-night hog campaign on a tight budget, that removes the single most common failure point: a dead scope at two in the morning.
It also removes the need to carry spare cells or a power bank, which is more than a convenience on a stand where you cannot easily return to the truck. Combine that with a 35mm lens and you have a setup built around the actual hours hogs are active.
What to watch out for
The mount and the buttons are the practical issues. Plan to check the base torque in daylight before you rely on the optic, and take a moment in the dark to learn the position of the power control rather than finding it by feel for the first time at midnight.
QC on arrival matters for this model specifically. Owners who report shadow-image defects describe a contrast problem where part of the image stays dark. If you see it out of the box, document it immediately and use the warranty, because that resolution has been the frustrating part in the feedback.
At two pounds, this is one of the heavier entries, and balance on an AR platform is a real consideration. If your rifle is already heavy at the muzzle, this may be the scope that tips it past comfortable for a long sit.
5. ATN Thor LTV 256 – the lightest optic for a light rifle
ATN Thor LTV Ultra-Light Weight Thermal Scope. The Thor LTVs are Premium Thermal Scopes for Hunting That utilize Advanced Thermal Vision. Easy to use Advanced Thermal Scopes
256x192 12um sensor
1.5x-4.5x magnification
60Hz refresh
1.4 lb with rings
Pros
- Very light at 1.4 lb including rings
- Wide 1.5x-4.5x range suits close hog work
- 90mm eye relief is genuinely comfortable
- Simple menu and One Shot Zero
Cons
- 256x192 limits detail at longer range
- Basic feature set versus costlier ATN models
The Thor LTV is built around one idea: put a usable thermal on a rifle without wrecking the balance. At 1.4 pounds including the ring-mounted package, and with 90mm of eye relief, it is the most comfortable optic here for a long sit on an AR-style hog rifle.
Reviewers frame it as the best-value lightweight thermal in ATN’s lineup, with the 1.5x to 4.5x zoom and 256×192 sensor proving adequate for close-range hog and predator work out to roughly 100 yards. Multiple owners bought a second unit, which is about as strong an endorsement as product feedback gets.
The 60Hz refresh rate gives a smoother image than the 50Hz and 30Hz units elsewhere in this roundup, and that smoothness matters when pigs move. SharpIR processing and One Shot Zero handle the image cleanup and alignment respectively.
Why the refresh rate matters here
A moving hog in a 256×192 sensor is a small, fast-changing object. A 60Hz refresh updates the image more often per second, so the pig tracks smoothly across the display instead of stepping in discrete jumps. If your hunting involves reacting to pigs that break and run rather than sitting on a feeder, that is a genuine advantage.
The 1.5x base does the other half of the job. You start wide, find the group, and only then zoom toward 4.5x. Scopes that start at 4x force the opposite order, and that is the mistake experienced hog hunters most often call out in the buying discussions.
Where the Thor LTV falls short
Resolution is the limit, and it is a real one. The 256×192 sensor will show you a hog with no hesitation at 100 yards, but it cannot separate fine features, which is why owners who wanted species detail or antler identification regret not stepping up a resolution tier.
Feature set is the second limit. Compared with the costlier ATN models there is no built-in laser rangefinder or advanced ballistic calculator on this variant. You are buying weight savings and simplicity, and that is a coherent package, but it is a package.
Standard 30mm ring mounting is a plus rather than a limitation here, because it lets you choose rings with a lower height and a better cantilever position for your rail. Just confirm the tube and ring height clear your rear sight or backup sight on an AR.
6. ATN Thor 5 LRF 4-16x – most features in one optic
ATN Thor 5 LRF Smart HD Thermal Scope w/Ultra Sensative Gen 5 Sensor, Video Rec, Built in LRF, Ballistic Calculator, RAV
320x240 12um Gen 5 sensor
4x-16x
LRF and ballistic calculator
2.1 lb
Pros
- Clear
- crisp image owners rate a step up from the Thor 4
- Laser rangefinder helps first-time thermal users
- Scope
- rangefinder
- ballistics and recording in one unit
- Responsive ATN customer support
Cons
- 320x240 resolution is modest for the price
- Only 11 ratings so the long-term record is limited
The Thor 5 LRF is the scope for someone who wants ranging, ballistics and recording built in rather than assembled from separate accessories. The built-in laser rangefinder, advanced ballistic calculator, recoil activated video and a custom reticle editor are all in the box, and the smartphone app adds smooth remote zoom.
Owners coming from the Thor 4 report visibly better picture and clarity, and hog hunters note that it zeroes quickly and holds up well in use. All eleven ratings on this listing are four stars or better, with no negative write-ups at all.
ATN builds and tests in its own Doral, Florida facility, which matters for warranty service on a scope you will be relying on at night in the woods rather than in a repair queue across an ocean.
The clearest criticism of this pick is that 320×240 is a modest sensor for what this scope costs. You are paying for the processing, the sensors and the software stack rather than for resolution, and for a hunter who wants clean video and a rangefinder that is a fair trade. For a hunter who simply wants to see hogs, the resolution is where the money went.

Who benefits from a built-in rangefinder
A rangefinder earns its place when you do not know the distance. If you shoot a known feeder with marked trees and a rangefinder card, an LRF adds little. If you walk into new timber every weekend, or hunt a ranch where the pigs come from more than one direction, the rangefinder plus a ballistic solution removes the guess that decides whether a shot connects.
First-time thermal users in particular find that an LRF builds confidence fast. Rather than estimating distance by eye in a picture they are still learning to read, they get a number and a hold solution, and they start taking shots instead of waiting for perfect conditions.
Where this Thor 5 variant is the wrong call
The 4x base is high for hogs. Any scope starting at 4x makes you work harder to find and hold a group, and it is the exact complaint experienced hog hunters raise about many budget units. If your hunting is feeders and close brush, look at a lower base magnification model instead.
Eleven ratings is a very small sample, and the review data itself flags the limited long-term record. Treat the strong owner sentiment as encouraging rather than proven, and confirm the warranty terms with the manufacturer before mounting.
At 2.1 pounds this is a substantial optic. On a heavy-barreled hog rifle that is fine. On a light AR setup it will change how the rifle carries, so account for it in your setup.
7. Pulsar Talion XQ35 – a proven scope with its mount included
Pulsar Talion XQ35 Pro Thermal Riflescope, 384×288 Sensor
384x288 17um sensor
NETD under 25mK
2.5x-10x
Prism mount included, 1.5 lb
Pros
- Feels solidly built with a magnesium housing
- Included prism mount praised as very durable
- Clear sight picture and good detection in total darkness
- Long runtime on the APS5 pack
- Light enough not to upset rifle balance
Cons
- One report of menu buttons failing within 30 minutes
- Some owners wish the mounting system were different
- Small rating pool of 10
- Uses proprietary APS battery packs
The Talion XQ35 has been in the lineup long enough that owners tend to already own several Pulsar thermals, and they rate it as one of their favorites. At 1.5 pounds with a magnesium alloy body and an IPX7 rating, it is built like a tool rather than a gadget, and it is recoil rated for 12 gauge, 9.3×64 and .375 H&H.
The 384×288 17um sensor at under 25 mK NETD is a proven combination, and detection is quoted up to 1,475 yards. For hog work that number is largely irrelevant, but the sensitivity behind it shows up in the dark brush and heavy timber where pigs actually bed.
The included multi-point prism mount is the quietly valuable part. Owners describe it as the most durable mount they have used, and it means you can set the scope forward on the rail for eye relief and cheek weld without buying rings first.
Photo and video recording, picture-in-picture aiming and ten reticle shapes in nine color modes cover the feature set. The housing mounts as a prism, which gives it a shorter, rounder profile than a tube scope and keeps it compact for pack-out.

One substantive negative review in the data describes menu buttons failing within about 30 minutes of use, which Pulsar tech support resolved under warranty. It is worth knowing that failure mode exists, and worth keeping your purchase documentation in the field bag rather than at home.
The battery pack design is another practical constraint. It runs on rechargeable APS packs rather than conventional cells, so you need a way to recharge overnight unless you carry a spare pack. A second APS5 pack is the accessory to buy with this scope.
A small rating pool means limited peer feedback, and several owners would prefer a different mounting system. If you are particular about rail position or run a forward-mounted red dot, check prism clearance before you commit.

What the prism mount actually solves
Eye relief on a hog rifle is a comfort issue that turns into an accuracy issue over a four-hour sit. The prism mount lets you push the scope forward, which lengthens eye relief without sacrificing cheek weld, and it stays put under recoil because it is a rigid cradle rather than a ring pair.
For a hunter running the same rifle in the dark every week, that is a quieter advantage than a feature list suggests. It also means one less purchase and one less failure point, since a scope held by two rings can shift while a prism holds the tube in a fixed channel.
Where the Talion is not the best value
Buying a 2.5x to 10x prism scope in 2026 means you are buying a generation behind on magnification range. For hogs at 100 to 200 yards that ceiling is fine. If you ever want to stretch a thermal across varmint and open-country work, you will outgrow it sooner than the format suggests.
Second, the proprietary battery is a real ownership cost. You are tied to one charging ecosystem, and the packs are the most common consumable in cold weather use. If you already own Pulsar gear, this is a non-issue. If you are starting fresh, factor the spare pack into the purchase.
Third, the menu button failure report, while isolated, happened early enough to be a warranty matter. That is a reminder to register the scope and keep the receipt, not a reason to skip the model.
8. Burris BTS35 V3 – the scope with a real control knob
Burris Optics BTS35 V3 Thermal Imaging RifleScope, 400×300 Screen Resolution, 50hz Refresh Rate, Video and Photo Recording, WiFi, Thermal Vision, Thermal Scope
400x300 VOX sensor, 12um
50Hz refresh
35mm F1.0, 7.8 by 5.9 degrees
1.7 lb magnesium
Pros
- F1.0 35mm lens gathers heavy light for a bright picture
- Rotary knob menu control allows fast field changes
- Nine color palettes for different cover and weather
- Hot track and stadiametric ranging assist with moving hogs
- 1.7 lb magnesium body
- Mounts to Picatinny or Dovetail
Cons
- 400x300 resolution is low for the price tier
- Only 2 ratings so the 5.0 average is not meaningful
- No written customer reviews to verify field performance
- Smaller reticle ecosystem than ATN
The Burris BTS35 V3 is interesting for one reason above the others: a rotary knob instead of a button cluster. Every menu-driven thermal we recommend in this roundup has a control interface that experienced hunters describe as clunky, and a physical knob with tactile feedback is the straightforward fix. You can change palettes and settings without looking at the display.
Behind that control, the hardware is strong. A 400×300 VOX sensor at 12um and 50Hz sits behind a 35mm f/1.0 lens producing a 7.8 by 5.6 degree class field of view, one of the wider picture windows at this resolution. The 1024×768 color OLED is bright, and the fast lens collects enough light to hold a usable image in the last minutes of dawn light.
Nine color palettes including iron, sepia and inferno let you match the display to conditions rather than living with one setting. Hot track and stadiametric ranging are the features that help with a moving group, and the mounting accepts both Picatinny and Dovetail rails.
Now the honest part. This listing has two ratings, both five stars, and no written review text. The 5.0 average carries essentially no evidential weight, and our assessment rests on the published specification set rather than on owner reports. Performance claims from the manufacturer should be treated as such until more feedback accumulates.
Why the lens matters more than the sensor here
An f/1.0 aperture is a light-gathering decision. In a hog blind at last light, or in fog with a cold front moving through, the difference between f/1.0 and a slower lens is the difference between a usable image and a dim one. That is why this scope pairs a 35mm fast lens with a sensor that is not the highest resolution available.
For identification work, resolution would be the better place to spend. For detection and sustained observation in poor conditions, the aperture is the more valuable of the two, and for a hunter sitting a feeder through a wet night that is the scenario that matters.
What to verify before you buy
Check the physical length. The listed dimensions run to 11.7 inches, which is long for a thermal and may need ring clearance on a compact AR upper. Measure before ordering rather than after.
Second, accept that you are buying a specification sheet rather than a track record. Two ratings is not evidence of field performance, and the custom reticle ecosystem is smaller than ATN’s, so if you like building your own reticles that is a limitation worth weighing.
Third, note that 400×300 is an unusual resolution that sits between the 384 and 512 tiers. It gives a slightly wider image than a 384 sensor, but the underlying detail per pixel does not jump. Judge it on the lens, the field of view and the control knob, not the resolution number.
9. ATN Thor 5 XD 3-30x – the highest resolution option
ATN Thor 5 XD Smart HD Thermal Scope w/ 1280×1024 Xtreme Definition Gen 5 Sensor, Video Rec, Built in LRF, Ballistic Calculator, RAV
1280x1024 Gen 5 12um sensor
3x-30x
LRF and advanced ballistics
2.7 lb
Pros
- 1280x1024 sensor gives true high-definition thermal detail
- 3x-30x zoom covers close hogs to long range
- LRF and advanced ballistic calculator for precise holdover
- Feature set includes One Shot Zero and Recoil Activated Video
- Three year manufacturer warranty
Cons
- Very heavy at 2.7 lb for a mounted optic
- Only 2 ratings so the 5.0 average rests on a negligible sample
- No written customer reviews on this listing
- Cost sits well beyond casual hog-hunting budgets
The Thor 5 XD is the only scope here with a genuinely high-definition thermal sensor: 1280×1024 at 12um, which is roughly four times the pixel count of a 384×288 panel. If you have ever been frustrated by a 256 or 320 sensor refusing to show you a hog standing behind grass, this is the resolution tier that removes the ceiling.
At 3x to 30x with a built-in laser rangefinder and an advanced ballistic calculator that compensates for temperature and environmental factors, it covers everything from a hog at 30 yards to an animal at several hundred. One Shot Zero, Profile Manager, Recoil Activated Video and a custom reticle editor round out a very complete feature set.
It also weighs 2.7 pounds. That is the heaviest optic in this roundup by a wide margin, and on an AR it changes how the rifle sits in your hands for an entire night. On a bolt-action hog rifle with a heavy barrel, the number matters much less.
Two ratings, both five stars, and no written review text. As with the Burris, the rating carries almost no weight. The specification set is genuinely impressive, and the evidence base for real-world field performance on this listing is effectively empty.
What high resolution actually changes
Resolution shows up in the situations where you need to be certain of what you are looking at. When a sow and piglets are stacked in brush, a higher-resolution sensor separates the individual animals instead of merging them into one bright shape. When you are deciding whether to take a shot at a partially obscured animal, detail reduces the guess.
It also matters for video review and for any scenario where you are identifying a specific individual. For general hog eradication, where the goal is a clean shot on an animal at 150 yards, a 384 sensor does the same job. High resolution is a capability you may not use every trip.
Where this scope is the wrong answer
Weight is the first honest objection. Two point seven pounds forward of the action on a semi-automatic rifle is a lot of optic for a job that is usually done at a feeder. If you are already fighting a heavy barrel, this will be the setup that ends an early night.
Second, cost. This sits at the top of the range by a wide margin, and most hog hunters will recover more practical value from a mid-tier 384 or 640 scope and a second battery. Buy this if you also shoot predators, do long-range work, or simply want the best available sensor.
Third, the evidence problem. You would be early on a model with very little owner feedback. That is a legitimate reason to wait a season, not a reason to dismiss the scope.
10. Athlon Cronus ATS PRO – ultralight, with a hardware caveat
Athlon Cronus ATS PRO 25 P-250 Thermal Scope, 3.6-14.4X Magnification, 256×192 Sensor, 25mm Lens, 7 Color Palettes, Pick Mount (210145)
256x192 12um sensor
OLED display
3.6x-14.4x
5.5 oz, 10+ hour battery
Pros
- Exceptionally light at 5.5 oz
- close to a conventional day scope
- Good thermal detection in dense cover
- Seven palettes with adjustable brightness and contrast
- Long battery life
- Usable as a scope or a handheld monocular
Cons
- Included rail mount too narrow for some rails with no replacement
- One owner reports it will not hold zero with .223 ammunition
- Fidelity is lower than higher-resolution sights
- Serial number sits inside the objective lens cover
The Cronus ATS PRO is the lightest optic in this roundup by a wide margin at 5.5 ounces, which is close to the weight of a conventional day scope. If weight is your binding constraint, no other pick here comes close, and the 10+ hour battery means the light weight does not come with an endurance penalty.
It is also the most polarizing scope here, at 3.9 stars from 38 ratings, a rating pool large enough to show real patterns in either direction. Owners love the weight class, the seven color palettes, the accessible menus and the ability to scan handheld. Image fidelity is lower than higher-resolution sights, which is expected from a 256×192 panel.
A built-in ballistic calculator, WiFi, auto-shot recording and a 3.6x to 14.4x magnification range cover the feature set. A Picatinny mount is included, and the 25p-250 model carries a seven degree field of view.
The 12 percent one-star rate is not about imaging. Both recurring complaints concern hardware: the included Picatinny mount is reported as too narrow for certain rails with no replacement offered, and one owner says it will not hold zero on .223 ammunition. Those are fixable in different ways, but only one of them is fixable by the seller.

The serial number sits inside the objective lens cover, which is an awkward detail when registering the warranty. Note it down when the scope arrives rather than digging for it later, because warranty service is exactly the situation where you do not want to be fumbling with a scope that will not hold a zero.
Like all thermal units, it shows only objects with a heat signature. It will not see through glass, and it will not image a cold-blooded target, which matters little for hogs but shapes expectations if you plan to use it for other work.
Scanning handheld is a genuinely useful habit with this scope. At 5.5 ounces you can carry it on a neck strap to glass a field, then transition to the rifle when pigs commit.

When the weight saving actually pays off
On an AR platform, a thermal scope is competing with an offset red dot, a magnifier and a sling. Five and a half ounces leaves room for all of them. Every other pick in this roundup pushes you toward choosing between the thermal and the daytime optic, and on a fast-moving hog rifle that is a real constraint.
The 10+ hour battery compounds the benefit. On a light rifle you are not adding a power bank or a second battery to your kit to cover a long sit, which is a meaningful saving when you are walking a ridgeline to reach the stand.
What to confirm before mounting
Verify rail width before you commit. The narrow included mount is the most common complaint in the feedback, and several owners had to solve the problem themselves because no replacement hardware was offered. Check your rail and be prepared to use a different mount if it does not match.
Zero retention is the second question. If you shoot .223, the single report of a zero that would not hold is worth taking seriously, and a quick-detach mount plus a witness mark on the rail makes re-zeroing trivial. Confirm you can return it if it will not hold on your ammunition.
Lastly, set expectations on image quality. A 256×192 sensor will find hogs in dense cover, which is the job. It will not give you the crisp picture of the 640 or 1280 tiers, and paying more for the Athlon would mean buying a different scope.
How we picked these 10 thermal scopes
Every scope here was judged against the same five questions, which we applied to the published specification set, the owner review patterns, and the recurring complaints in hunting forum discussions. We did not claim hands-on field testing on this page, and the per-product write-ups reflect published data rather than measured performance.
Can it hold a group? We weighted base magnification and field of view more heavily than maximum magnification, because hogs are shot in groups inside a few hundred yards.
Will it last the night? Battery runtime, weather sealing and the availability of spare cells or power bank input carried real weight, and cold-night performance was treated as the deciding factor in ties.
Does it return to zero? Mount type, included hardware and quick-detach capability matter on a hog rifle that moves between guns and calibers.
Is the interface usable at midnight? Menu complexity is a safety issue in the field, not an inconvenience, and scopes with physical controls scored better.
Is the evidence base real? Where a listing has two ratings, we said so plainly and rested the assessment on specifications rather than owner reports.
The gap in current published roundups is that they are either field-tested for coyotes or written for hogs with no measured testing behind them. This list tries to sit in the middle: hog-specific decision logic, with spec honesty about what has and has not been validated.
Buying guide: 384 vs 640 vs 256 for hog hunting
The right answer depends on the distance you actually shoot, not on which tier sounds most advanced. Here is how the three main sensor classes map to hog work.
256×192 sensors detect and identify a hog at close and medium range reliably. Owners of the units in this list report taking animals from 10 to 100 yards without difficulty. What they cannot do is resolve fine detail, which is why several reviewers recommend stepping up a tier if you shoot past 150 yards.
384×288 is the sweet spot for most hog hunters. It gives a noticeably sharper image than a 256, a wider usable picture, and it costs less than a 640 body. Several owners in this roundup explicitly recommend the 384 over the 256 for the screen quality difference alone.
640×480 and larger earns its cost when you have fog, rain, a cold front, or a long shot. The NETD figures are lower, meaning higher sensitivity, and that is what carries you through poor conditions. For open fields and mixed weather, a 640 is the right call. For a feeder in dry October weather, you are paying for reach you may never use.
For our own money on feeder work, a 384 is the correct buy. On big ranch ground with weather that changes, step up to 640.
Objective lens: 19mm, 25mm, 35mm and 50mm
The objective lens diameter drives field of view more than any other spec, and for hogs it is arguably more important than resolution. A larger lens gathers more light and produces a wider picture, which is what keeps a moving sounder in frame.
A 19mm objective gives the widest view and is the right choice in extremely tight cover or when you glass with the scope at very close range. A 25mm sits in the middle and handles most feeder and creek-bottom situations. A 35mm is the best compromise for mixed terrain, which is why it appears in two of the picks here. A 50mm gives you reach and a bright picture at distance, at the cost of a narrow view up close.
Buyers in the forums describe picking a 50mm or 60mm objective for a feeder setup and immediately regretting the narrow field of view. That is the most common objective lens mistake we found, and it is entirely avoidable.
Base magnification and field of view with a sounder
Base magnification is the power you start at, and it decides whether you see a group or a single animal. A scope that starts at 1.5x or 2x lets you acquire a sounder and then zoom to the individual. A scope that starts at 4x or 5x forces you to zoom out digitally, which softens the image exactly when animals are moving.
The complaint that shows up repeatedly in hog hunting discussions is simple: you look impressive while one animal is standing still, and then the whole group bolts and you lose them. That is a field of view problem, and the fix is a low base magnification and a large objective, not a better sensor.
For hog work, we would take a 1.5x or 2x base over a 4x base every time, even at the same resolution tier.
NETD, refresh rate and detection vs identification range
NETD is noise equivalent temperature difference, measured in millikelvin, and it describes how small a temperature difference the sensor can resolve. Lower is better. A scope under 25 mK is the current practical benchmark, and the difference becomes obvious in fog, rain and at long range rather than on a clear night.
Refresh rate in hertz determines how often the image updates. 50Hz is the common standard, and 60Hz is smoother. When pigs run, the higher refresh means they track across the display rather than jumping in steps.
Detection, recognition and identification range are three different things. Detection means you see something warm. Recognition means you can tell it is an animal. Identification means you can tell what it is. The advertised detection range is almost always the first of those, measured against a large warm object on a clear day. Your identification range for a hog in brush is a fraction of it, which is why we do not rank by that number.
Reading a spec sheet correctly matters more than the number itself. When a scope quotes 2,000 yards, the honest question is not how far can you see a hog, but how far can you tell a hog from a deer at 400 yards.
When you actually need a laser rangefinder
You need a rangefinder when you do not know the distance. If you shoot a known feeder with marked trees, a stadiametric rangefinder or a rangefinder card is enough. If you walk into new timber, hunt land with pigs coming from multiple directions, or set up in a spot you have never sat before, a laser rangefinder earns its place.
A rangefinder also builds confidence for first-time thermal users, because it replaces distance guesswork with a number. Paired with a ballistic calculator, it also means environmental factors are compensated for automatically rather than through memory.
The value here is situational. A hunter with one feeder never pays off the cost. A hunter who moves the blind twice a season gets it back in the first season.
Thermal vs night vision for hog hunting
Thermal wins for hogs, and the reason is physical rather than brand-driven. Hogs are large, dark-coated animals that hold a strong heat signature, and thermal reads that heat directly rather than amplifying available light. Night vision amplifies starlight and moonlight, which means it struggles in heavy cover and on an overcast night with no ambient light at all.
Night vision has two real advantages. Depth perception is better, because you are still looking at a normal image, and it typically costs less. Night vision also produces a more natural-looking picture at very close range.
For hogs specifically, a large warm target in low light is close to the ideal thermal use case, which is why thermal is the right answer for the majority of hog hunters. If you also hunt in heavy daytime brush, where thermal depth perception is weak, night vision is worth considering as a second optic. Our picks for spotting scopes for hunters cover the glassing side of that workflow.
Do hogs see infrared? Light discipline and spooking
Hogs are not known for reacting to infrared the way some predators reportedly are, but they are not comfortable animals, and the practical answer is that you should assume they can detect your presence. Wild hogs have excellent smell, sound night vision and a strong tendency to spook from movement and from lights they have learned to associate with danger.
The practical guidance is the same for any hog hunt: approach downwind, move slowly, avoid white light near the bedding area, and treat a thermal as a detection tool rather than a license to be careless. Most hunters in the discussions we reviewed run a red-filtered or dimmable light and turn it off entirely when animals settle, rather than lighting the scene for the whole sit.
Many hogs are active well before full dark, which means a decent portion of hog work happens in the last hour of light. A thermal works in daylight, so the same optic covers the approach and the night portion of the hunt.
Scope, clip-on or handheld: what experienced hog hunters carry
Experienced hog hunters in the buying discussions converge on a three-part kit, and the reasons are practical rather than enthusiast-driven.
A handheld thermal or monocular handles the walking. Glassing all night on the rifle is tiring, and vehicle-mounted scanning lets you cover more ground faster before committing to a stand. Several owners in the data recommend buying a monocular alongside the scope for exactly this reason.
A wide-view close-range unit covers the last 50 yards in brush, where a 4x scope is useless. Users pair a low-power unit for close-range awareness rather than trying to make a 4x-plus scope do that job.
A clip-on thermal answers a different question: if your hog rifle is also your daytime deer rifle, a clip-on lets you keep a conventional daytime scope and add thermal capability in the field. The trade is added weight on the front end, heavier glass, and a less balanced rifle, which is why many hunters eventually move to a dedicated thermal.
Our recommendation is a dedicated thermal for the night optic plus a handheld for scanning, and to treat a clip-on as the answer only if one rifle must do both jobs.
Mounting a thermal on an AR-15 hog rifle
Two things decide whether an AR works with a thermal: rail space and weight. A 1.4 to 2.7 pound optic forward of the action changes the balance of the rifle, and on a semi-automatic platform that front weight can make the rifle feel like it wants to tip.
Rail space is the second issue. Scopes with a cantilever mount need more rail behind them than a compact tube design, and if you run a backup red dot you need to confirm both clear. The lighter picks here, the Athlon at 5.5 ounces and the AGM Rattler V2 at 6.34 ounces, are the ones that pair most easily with a full AR setup.
Whatever you mount, mark your rings or use witness marks so the scope returns to the same position after every removal. Quick-detach mounts and a grease pencil line are the cheapest insurance against re-zeroing in the dark, and it is a genuine problem on a multi-gun hog setup.
Our broader notes on daytime rifle scopes are in our guide to rifle scopes for deer hunting, and pack-out for long sits is covered in our hunting backpacks for elk hunting picks, which apply equally to an all-night hog camp.
Cold-night battery life and weather sealing
Published runtime figures are measured at room temperature, and cold nights shorten them, sometimes noticeably. For planning, treat a published figure as an upper bound rather than a promise, and prioritize scopes with removable or dual internal batteries so you can swap without losing your zero.
Weather sealing matters more than most buyers expect. Hog hunters work in the wettest conditions of the year, and IPX7 means the scope is rated for submersion, which is a meaningful difference from IPX4 splash resistance when you are sitting in a leaking blind in a downpour.
The scopes here run from 4.5 hours on CR123 cells up to 15 hours on dual internal rechargeable batteries. For an all-night sit, anything under six hours needs a power plan.
Two categories we did not include
Handheld monoculars and binocular-only products. These are excellent tools and several hunters in the discussions pair one with a scope, but they are not riflescopes and they do not belong in a ranked list of scopes for hog hunting. We mention them as accessories where they fit into the workflow.
Scopes where the evidence is thinner than the price. Where a listing had only two ratings and no written review text, we flagged it in the write-up rather than quietly ranking it on its spec sheet. Two of the entries in this list fall into that category, and we would rather tell you than pretend the owner feedback exists.
Frequently Asked Questions
What is the best thermal scope for hog hunting?
The AGM Rattler V2 25-256 is the best all-round choice for most hog hunters. It combines a wide 25mm field of view, a 3.5x base magnification, an 11.5 hour runtime and IP67 sealing at only 6.34 ounces. For open fields, a 640×480 model with a laser rangefinder gives you more reach and sensitivity.
Is night vision or thermal better for hog hunting?
Thermal is better for hogs. Hogs are large animals with strong heat signatures, and thermal reads that heat directly instead of amplifying available light, so it works in heavy cover, on overcast nights and through light fog where night vision struggles. Night vision holds advantages in depth perception and daytime-capable setups, but for identifying hogs at feeder range thermal is the stronger tool.
Do hogs see infrared light?
Hogs are not widely documented as reacting to infrared specifically, but they have excellent smell and hearing and they spook readily from movement, sound and bright light. The practical answer is to assume they can sense your presence, approach downwind, move slowly, and use a dim or red-filtered light only when necessary rather than lighting the whole scene.
Can you hunt with a thermal scope during the day?
Yes. A thermal scope works in daylight and does no damage to the sensor in daylight. Many hogs are active well before full dark, so many hunters start with a thermal at last light and continue after dark with the same optic. Thermal cannot see through glass and only images warm objects, so daytime use is best aimed at live animals rather than general scouting.
What are the disadvantages of a thermal scope?
The main drawbacks are weight, which typically runs 1.4 to 2.7 pounds and affects rifle balance, especially on an AR platform; battery life, which is reduced in cold weather; a learning curve for menu-driven controls; depth perception that is worse than night vision; and the fact that entry-level 256 sensors cannot resolve fine detail. Thermal-only optics also cannot double as a daytime scope, so a clip-on may be a better choice for a dual-purpose rifle.
Which thermal scope should you buy for hogs?
Start with the distance and the group size, not the brand. If you hunt a feeder inside 150 yards, the AGM Rattler V2 25-256 is our pick in 2026 for the wide picture, the long runtime and the light weight. If you want the sharper screen at the same distance, the AGM Rattler TS25-384 is the step up, with a battery budget attached.
If your pigs come out of thick cover and you need to last the whole night on one charge, the AGM Adder 35-384 gives you both the 35mm field of view and up to 15 hours. If your rifle is a light AR and weight is the constraint, the ATN Thor LTV 256 is the comfortable answer, and the Athlon Cronus ATS PRO is the ultralight one if you can verify the rail fit first.
For open fields, changing weather and a need to range targets, the Pulsar Thermion 2 LRF 50mm brings the sensitivity and the reach. For the highest resolution available, the ATN Thor 5 XD 3-30x is the top of the list, and for a durable proven scope with its mount in the box, the Pulsar Talion XQ35 remains a sensible buy.
Whatever you choose, spend an evening with the controls on the bench before you need them, mark your mount so the scope returns to position, and confirm your state and federal rules on night hunting and artificial light before the season starts. Hogs are shot late, often after legal sunset and sometimes illegally, so check the current regulations for the ground you hunt rather than assuming.
