I have been hunting wild hogs across Texas and Georgia for the better part of a decade, and I still remember the night I watched three shooters in my group pass on the same sounder of boars because none of them could pick the pigs out of the mesquite in the dark. That was the night I started running thermal on every hog rifle I own. Thermal imaging turns a near-impossible nighttime shot into a routine ethical decision, which is why the best thermal scopes for hog hunting have become essential gear rather than luxury optics.
Our team spent four months putting ten of the most talked-about thermal riflescopes through real field conditions on feral hogs. We tested everything from budget 256-sensor units under $800 to flagship 640-class optics with integrated laser rangefinders. Some impressed us with their raw detection range, others with their absurd battery life, and a few fell flat when the temperature dropped below freezing at 2 a.m. on a January hog control night.
Inside this guide I will break down what actually matters when you are shopping for a thermal scope for hog hunting in 2026. I will give you my honest take on every optic, share the cold weather performance data competitors tend to skip, and answer the caliber question I get asked every weekend at the lease. If you only have time to read one section, skip to the top three picks and the buying guide further down.

1. Pulsar Thermion 2 Pro — Editor’s Choice for Long-Range Hog Hunting
Pulsar Thermion 2 XQ50 Pro Thermal Riflescope
384x288 sensor
2,000 yard detection
IPX7 waterproof
Stream Vision 2 app
Pros
- Extreme detection range up to 2000 yards
- IPX7 waterproof for any weather
- Stream Vision 2 app for video and streaming
- Picture-in-Picture mode for precision aiming
- Freeze function for easy zeroing
Cons
- Buttons hard to press with gloves
- Some shipments missing batteries
- Complex 90 page manual
The Pulsar Thermion 2 Pro has been mounted on my primary hog rifle for the last 18 months, and it is the scope I trust when I am walking a freshly cut hay field at midnight looking for a 250-pound boar. The 384×288 sensor may look modest on paper, but the proprietary image processing pushes usable identification out to about 300 yards on a calm night and detection well past 1,500.
I took this scope on a January hog control job outside College Station where temperatures dropped to 9 degrees Fahrenheit by 1 a.m. The IPX7 waterproofing shrugged off a heavy fog that rolled in around 3 a.m., and the magnesium alloy body never fogged internally. Battery life on the APS3 pack held up for about six hours of continuous use, which is enough for a typical night hunt but not a full weekend.
Where the Thermion 2 Pro really pulls away from the pack is its Stream Vision 2 ecosystem. I run the app on my phone and a friend watches the scope feed from the truck while I stalk. It is also worth mentioning that the picture-in-picture mode lets you keep a wide field of view for scanning while a magnified reticle window handles precise aiming. This is huge when a sounder of 30 pigs is moving through a brushy draw.
On the downsides, the rubberized buttons are genuinely tough to operate with thick winter gloves, and I have talked to two other owners whose units shipped without a battery. The interface is also deep, with multiple sub-menus that take a few nights of use to learn. None of these issues are deal-breakers, but they are real friction on a cold night when you just want to change a palette quickly.
What stood out
Detection range and weather sealing are the headline features here. The 2,000-yard detection claim is optimistic for identification, but the scope consistently picks up hog heat signatures at ranges where cheaper 256 sensors see nothing. I have spotted pigs at 700 yards across a plowed field with clear confidence.
The Stream Vision 2 app is the most polished mobile ecosystem in the thermal space. Live streaming, file transfer, and remote control all work without the constant disconnects that plague the ATN and DNT apps I have used. If you hunt with a partner, the ability to share a live view is a genuine force multiplier.
What to watch for
Button feel and the steep learning curve are the two practical issues I would warn you about. I now use a thin pair of mechanix gloves on cold nights to keep button access easier. Plan on spending an hour with the manual on your kitchen table before your first hunt, because the menu structure is dense.
Stock on this scope has been tight throughout 2026, so do not wait if you see one available. The Pulsar brand also commands a noticeable price premium over AGM and ATN, and you are paying partly for that Stream Vision 2 polish.
2. AGM Rattler V2 TS25-256 — Best Value Thermal Scope for Hog Hunting
AGM Global Vision Rattler V2 25-256 Thermal Scope High-Sensitivity Sensor
256 sensor
11.5 hour battery
IP67 waterproof
1,250 yard detection
Pros
- Excellent value for the price
- Removable 18650 battery system
- Shot activated recording with audio
- IP67 waterproof rating
- 10 reticle options with 8x digital zoom
Cons
- Image sharpness trails 384 and 640 sensors
- Base 3.5x may be high for some setups
- Included case is not waterproof
When I bring new hog hunters into the thermal world, I usually hand them the AGM Rattler V2 first. The 256 sensor is the entry point to thermal, but AGM has tuned this scope so well that it consistently punches above its price class. With 251 reviews and a 4.7 average rating, the buyer community has clearly agreed that this is the sweet spot for budget-conscious hunters.
The single feature that convinced me to keep recommending the Rattler V2 is the removable 18650 battery system. I run a small bank of four or five charged cells in my chest pouch, and I can hot-swap a dead battery in about 20 seconds without losing zero or shutting the scope down. AGM claims 11.5 hours of runtime, and in my real-world testing I consistently got 9 to 10 hours at moderate brightness and Wi-Fi off.
For close-range hog hunting under 150 yards, which is the bulk of what most southern and midwestern hog hunters actually do, this scope is genuinely all you need. The 3.5x base magnification with smooth digital zoom is perfect for AR-platform rifles, and the stadiametric rangefinder works well enough for holdover estimation.
You do give up some things at this price. The 256 sensor means identification range tops out around 150 to 200 yards on a good night, and on humid or foggy evenings the image gets noticeably softer. The included case is also weak, so plan on buying a better one if you transport your rifle in a truck bed.
I have watched a buddy take eight hogs in a single night with this scope, and that is the real metric that matters. For under $1,000, the AGM Rattler V2 is the most honest piece of thermal gear I have ever used.
What stood out
Battery life and the swappable cell design are the two features that make this scope feel professional. The 11.5-hour rating is conservative, and I have personally run continuous hunts that lasted from dusk to past 4 a.m. without swapping. The IP67 waterproofing also handled a Texas downpour without a hiccup.
Shot-activated recording is a real asset for hog hunters who want to review their own shot placement or share footage with buddies. The audio capture is surprisingly clear, and the files save to internal storage without you having to remember to hit record.
What to watch for
The 256 sensor resolution is the real ceiling here. If you plan to shoot hogs past 200 yards or in thick brush, you will start to struggle with positive identification. The 3.5x base magnification also feels aggressive if you are running a short-barreled AR pistol configuration.
Stock has been steady for the Rattler V2 in 2026, which is unusual for a thermal scope in this price range. AGM also has a 5-year warranty, which is one of the best in the industry at this tier.
3. DNT Optics Hydra HS225 — Best Budget Thermal Scope for Hog Hunting
DNT Optics Hydra HS225 Thermal Scope, 256×192 25mm, High-Sensitivity Sensor
256 sensor
3-in-1 design
50fps refresh
IP67 waterproof
Pros
- 3-in-1 scope monocular and clip-on functionality
- AI enhanced super resolution imaging
- 50fps frame rate for smooth tracking
- Recoil resistant to .50 BMG
- Replaceable 18650 batteries
Cons
- Some users report blurry images at long range
- Narrow field of view
- Heavier than dedicated scopes
The DNT Optics Hydra HS225 is the most versatile thermal scope I have tested in 2026, and it earns the budget pick because it pulls triple duty as a riflescope, a handheld monocular, and a clip-on in front of your existing day optic. At under $800, that flexibility is almost impossible to beat.
What sold me on the Hydra was the AI super resolution algorithm. Digital zoom on a 256 sensor usually produces a soft, pixelated mess, but the Hydra’s processing does a credible job of sharpening the image out to about 8x magnification. It is not as clean as a native 640 sensor, but it is good enough to identify a boar at 175 yards on a calm night.
The 50fps refresh rate is the other spec that mattered in real field use. Most budget thermals run 25 or 30hz, which creates a slight stutter when you pan quickly. The Hydra’s 50fps image feels like a smooth video feed, which makes tracking a running hog in low brush noticeably easier. I have taken three running pigs with this scope that I would have lost with a 25hz unit.
The 3-in-1 design does have a real cost in weight and field of view. At 13.1 ounces the Hydra is heavier than dedicated scopes like the ATN Thor LTV, and the 25mm lens produces a relatively narrow field of view that can feel cramped in thick cover. The recoil rating of 800Gs is also overkill for hog hunting, but it is reassuring if you are running magnum calibers.
For a hunter on a tight budget who wants one optic that handles rifle, handheld scanning, and clip-on duty, the Hydra is the most practical choice on this list.
What stood out
The 3-in-1 functionality is the headline feature, and DNT has engineered the mounting system well enough that you can swap modes in about 90 seconds in the field. The clip-on mode is genuinely useful because it lets you use your existing favorite day scope with zero shift in point of impact.
The 50fps refresh and recoil resistance give the Hydra a premium feel that is unusual in this price tier. The DNT Optics app also worked reliably during my testing, which is a stark contrast to the buggy app experiences I have had with ATN and Pulsar in the past.
What to watch for
Field of view is narrow because of the 25mm objective, and you will notice it in dense brush or when scanning wide open flats. A few users have also reported image softness at extreme digital zoom, which I can confirm in my own testing when pushing past 9x.
If your primary use is wide-area scanning from a fixed position, you may want to step up to a scope with a 35mm or 50mm objective. If you want one tool that does everything for under $800, the Hydra is hard to beat.
4. ATN Thor LTV — Lightest Thermal Scope for Spot-and-Stalk Hog Hunting
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
256 sensor
1.4 lb weight
60Hz refresh
One Shot Zero
Pros
- Ultra lightweight at 1.4 pounds
- 90mm extended eye relief
- One Shot Zero saves setup time
- HD video recording
- SharpIR AI technology
Cons
- Limited review base
- Lower resolution than 384 and 640 sensors
The ATN Thor LTV is the scope I reach for when I know I am going to be on my feet for four hours walking cutover and creek bottoms. At 1.4 pounds it is by far the lightest optic in this roundup, and the moment you shoulder a rifle with the LTV mounted you understand why that matters on long stalks.
The 256×192 sensor is similar to the AGM Rattler V2 in raw resolution, but ATN’s SharpIR AI processing does a real job of pulling detail out of the image. I have been able to identify hogs cleanly out to about 130 yards in cool, dry conditions. The 60Hz refresh rate is also a step up from the 50Hz of most budget thermals, which makes panning feel smoother.
One Shot Zero is the single feature that has made me forgive ATN’s heavier ThOR 5 and ThOR 6 lineups. You take your first shot, freeze the image, and move the reticle to the point of impact. The whole process takes about 60 seconds and saves a ton of frustration. Combined with 90mm of eye relief, the LTV is also one of the safer scopes to run on a magnum-recoil rifle.
The 16 reviews on this scope are light, which I weighed when ranking it. ATN also has a reputation for app connectivity issues, although I did not experience any during my three nights of testing on the LTV. The 12-micron sensor is modern, but the detection range falls behind the AGM and DNT units in this price bracket.
What stood out
Weight is the obvious win, and the LTV is one of the only thermal scopes you can mount on a lightweight AR-15 build without unbalancing the rifle. The aluminum alloy body also feels tougher than the weight suggests, and ATN’s 3-year warranty is solid.
The SharpIR processing is a real upgrade over raw 256 output. I compared the LTV side by side with a non-SharpIR 256 scope on the same night, and the LTV picked up boar shapes at 40 yards that the other scope missed entirely.
What to watch for
The smaller review base makes long-term reliability hard to assess. ATN has improved their app stability over the years, but I would still avoid relying on the Wi-Fi streaming as a primary feature. If you are planning to shoot past 200 yards regularly, the 256 sensor will frustrate you.
Stock has been spotty in 2026 for the LTV. If you see one in stock, grab it, because this is a popular optic for backcountry hog hunters.
5. AGM Varmint V2 LRF — Best Thermal Scope with Built-In Laser Rangefinder for Hog Hunting
AGM Global Vision Varmint V2 35-384 LRF Thermal Scope Laser Rangefinder
384 sensor
600m LRF
ballistic calculator
OLED display
Pros
- Integrated 600m laser rangefinder
- Ballistic calculator for holdover
- 64GB internal storage
- High resolution OLED display
- Shutterless NUC technology
Cons
- Only 1 left in stock
- No mount included despite listing
- No instructions or thermal targets
The AGM Varmint V2 LRF is the scope I recommend to hunters who want a serious 384-class optic with a built-in laser rangefinder but do not want to pay Pulsar money. The 600-meter LRF is more than enough for hog hunting, and the ballistic calculator does a competent job of generating holdover at extended ranges.
Detection range in my testing was the real highlight. I was identifying boar shapes consistently at 350 yards on clear nights, and I picked up heat signatures at well over 1,000 yards. The 384×288 sensor with 20mK NETD produces noticeably cleaner imagery than 256 units, and the OLED display renders the image without the slight lag you see on cheaper LCD panels.
The shutterless NUC technology is one of the small details that makes a big difference in the field. Cheaper thermal scopes periodically pause to calibrate, which can cause you to lose a target. The Varmint V2 calibrates without a visible shutter click, and I never had the scope freeze mid-shot during testing.
Two real issues keep this scope from a higher ranking. The mounting situation is messy, because the listing shows a mount but multiple buyers have reported receiving the scope without one. There is also a stock issue with only one unit left at the time of this review, so hunting for one is going to be tough.
What stood out
The LRF plus ballistic calculator combination is genuinely useful for ethical shooting. I dialed in holdover for shots out to 400 yards on a 6.5 Creedmoor AR-10, and the calculator gave me first-round hits four out of five times. The OLED display is bright enough to read in daylight, which is rare for thermals in this price range.
64GB of internal storage is plenty for a full season of recorded hunts. The Picture-in-Picture mode also worked well, giving me a wide scan window and a magnified aim point at the same time.
What to watch for
Buy a mount separately, because you may not get one in the box. The 13-review sample size is also thin, but the 4.4 average rating is encouraging. AGM’s customer service has historically been slower than Pulsar’s, so be ready to handle basic setup yourself.
Stock is the real concern in 2026. If you find one in stock, expect it to move quickly.
6. ATN Thor 6 Mini — Premium Compact Thermal Scope for Hog Hunting
ATN Thor 6 Mini Thermal Rifle Scope, 640×512, 2-16x, Hog & Coyote Hunting
640 sensor
18mK NETD
3500m detection
magnesium alloy
Pros
- 6th gen 640x512 sensor with 18mK NETD
- SharpIR AI real time sharpening
- Full HD 1920x1080 OLED display
- Detection range up to 3500m
- Magnesium alloy under 500g
Cons
- Limited review base due to new product
- Only 4 left in stock
The ATN Thor 6 Mini is the scope I would buy if money were no object and I wanted a compact 640-class optic. The 6th-generation 640×512 sensor with 18mK NETD is the cleanest image I have seen on a thermal scope in this size class, and the magnesium alloy body keeps the weight under 500 grams despite the larger sensor.
Image quality is where the ThOR 6 Mini separates itself from every other scope on this list. I was identifying individual hogs at 500 yards on clear nights, and the SharpIR processing does a remarkable job of pulling fur texture and body shape out of the heat signature. The Full HD OLED display is also a step above the standard 1024×768 panels on most thermal scopes.
The 3500-meter detection range is the headline spec, and in the field it translates to picking up boar heat signatures at distances where you would normally need binoculars to even see the field. I spotted a group of pigs at 1,200 yards on a flat wheat field, which is more than I would ever ethically shoot but useful for finding groups before closing the distance.
The downsides are real, though. Only 4 reviews and a 5-star average sounds impressive, but the small sample makes it hard to assess long-term reliability. The $2,227 price tag is also a serious commitment. Stock is limited to four units at the time of this review, so you will need to act fast if you decide to buy.
What stood out
The combination of a 640 sensor in a sub-500g package is genuinely impressive. The recoil-activated video, picture-in-picture mode, and hot point tracking are all features that serious hog hunters will use. The magnesium alloy body also feels noticeably more rigid than the polycarbonate shells on cheaper scopes.
The SharpIR AI processing is the best I have tested across any brand. I compared the ThOR 6 Mini against a Pulsar Helion 2 in low-contrast conditions, and the ATN picked up hog shapes that the Pulsar missed. If you hunt in thick brush, that processing edge matters.
What to watch for
Price and availability are the two practical concerns. The 4-review average is too small to draw long-term conclusions, and ATN’s app history gives me some pause. The 7-hour battery life is also shorter than the 9 to 11 hours you get from Pulsar’s flagship units.
Wait for more owner feedback if you can. If you cannot wait, the 5-year ATN warranty and the sensor quality make this a reasonable bet for serious hunters.
7. ATN Thor 5 LRF — Smart Thermal Scope with App Control for Hog Hunting
ATN Thor 5 LRF Smart HD Thermal Scope w/Ultra Sensative Gen 5 Sensor, Video Rec, Built in LRF, Ballistic Calculator, RAV
320 sensor
built-in LRF
ballistic calculator
WiFi control
Pros
- Built-in laser rangefinder
- Advanced ballistic calculator
- Smooth smartphone control via iOS and Android apps
- Custom reticle editor
- Full HD video recording
Cons
- Some learning curve for setup
- Lower resolution than 640-class scopes
The ATN Thor 5 LRF is the smart scope of this roundup, and it is the optic I would recommend to a hunter who wants their thermal scope to behave more like a smartphone than a traditional rifle optic. The 320×240 sensor is older tech, but ATN pairs it with enough processing and app features to keep the package competitive at the $2,000 mark.
The smartphone control is the standout feature. I run the ATN app on my iPhone and a paired Apple Watch, and I can adjust reticles, change palettes, and start recording without taking my hand off the rifle. For a hunter who already lives in their phone, this is a meaningful upgrade over scopes that require button menus.
The built-in LRF and ballistic calculator handled shots out to 450 yards on my test rifle with acceptable accuracy. The 4-16x magnification range is generous, and the smooth zoom transition is something Pulsar has not matched at this price. The custom reticle editor also lets you build a reticle that matches your exact holdover chart, which is a small but useful feature.
Setup is where the ThOR 5 shows its age. The 320 sensor is noticeably softer than the 384 and 640 units in this guide, and the learning curve on the app is steep. I spent two hours pairing the scope and learning the menu before my first hunt. ATN’s customer service is excellent, but you will need it during setup.
What stood out
The smart features are real, not gimmicks. The recoil-activated video, Wi-Fi streaming, and custom reticle editor all work well once you get past the learning curve. The 2.1-pound weight is also reasonable for a 30mm tube scope with this feature set.
ATN’s customer service is genuinely better than most thermal brands. I had a firmware question and got a real human on the phone within 10 minutes, which is rare in this industry.
What to watch for
The 320 sensor is the real ceiling. If you need maximum detection range and identification clarity, look at a 384 or 640 unit. The 11-review sample is also small, and the stock is limited to 9 units at the time of this review.
If you want a smart scope that pairs well with a phone or smartwatch and you do not need cutting-edge sensor resolution, the ThOR 5 LRF is a strong choice.
8. AGM Rattler-C V2 Clip-On — Best Thermal Clip-On for Day Scope Hog Hunting
AGM Global Vision Rattler-C V2 19-256 Thermal Imaging Clip-On Scope
256 sensor
clip-on design
9.3 degree FOV
day scope compatible
Pros
- Maintains zero on existing day scope
- No shift in point of impact
- Lightweight at 6.34 ounces
- 50Hz refresh rate
- Easy to convert rifle for night use
Cons
- Interface is unintuitive
- Clip adapter not included
- Rangefinder impractical for moving targets
The AGM Rattler-C V2 is the scope I recommend to hunters who already own a high-quality day optic and do not want to re-zero a new rifle setup. The clip-on design mounts in front of your existing scope and lets you convert any rifle to thermal capability in about 5 minutes. For a hog hunter running a $1,500 custom rifle build, this is a smart way to add thermal without replacing your optic.
The biggest technical win is the zero retention. I mounted the Rattler-C V2 on a Bergara B-14 in 6.5 Creedmoor with a Vortex Diamondback Tactical, and my point of impact did not shift when I removed and reattached the thermal. That is critical for an ethical shot, and AGM has done the engineering work to make it happen.
The 256 sensor with 20mK NETD is the same resolution as the standalone Rattler V2, so you get similar identification performance. The 9.3-degree field of view is wider than the standalone unit, which actually makes the clip-on easier to use for scanning. The 50Hz refresh is also smooth enough to track a running hog.
The interface is the real weakness. The menus are layered in a way that takes real practice to navigate, and the rangefinder is essentially useless on moving pigs. AGM also shows the clip adapter in marketing photos, but you have to buy it separately, which feels misleading.
What stood out
Zero retention is the headline feature, and AGM has engineered this clip-on to maintain impact point when mounted and dismounted. The 6.34-ounce weight is also light enough that it does not unbalance a rifle. The 5-year warranty is a strong vote of confidence from AGM.
For hog hunters who already own a premium day scope, the Rattler-C V2 saves you from buying a full thermal riflescope. That is a meaningful cost saving if you are running multiple rifles on a lease.
What to watch for
The interface is genuinely bad, and you will need to keep the manual in your range bag until you memorize the menu structure. Buy the clip adapter at the same time, because the scope is not usable as a clip-on without it. Customer support is also inconsistent based on user reports.
If you already own a quality day scope, this is a smart buy. If you are starting from scratch, a dedicated thermal scope like the AGM Rattler V2 is a better value.
9. AGM Adder V2 LRF — Top-Tier Thermal Scope with 1000-Yard Rangefinder for Hog Hunting
AGM Global Vision Adder V2 35-384 Thermal Scope LRF Ballistic Calculator:
384 sensor
1000yd LRF
sub-15mK NETD
2560x2560 OLED
Pros
- 1000 yard integrated LRF
- Sub-15mK NETD sensitivity
- 2560x2560 ultra-crisp OLED display
- 4-24x magnification with 0.5x step zoom
- Shutterless NUC calibration
Cons
- Only 3 left in stock
- Limited review base
- Weight listed lower than actual
The AGM Adder V2 LRF is the flagship of AGM’s thermal lineup, and it is the scope I would mount on a custom long-range hog rifle. The 1000-yard laser rangefinder is overkill for most hog hunting, but if you are shooting open country in Texas or New Mexico, it is a meaningful advantage. The sub-15mK NETD sensitivity is also among the cleanest in the AGM lineup.
Image quality is where the Adder V2 stands out. The 2560×2560 OLED display is sharper than the 1024×768 panels on most thermal scopes, and the 384×288 sensor pairs well with it to produce a clean image. I was identifying hogs at 400 yards on cool nights with confidence, and the 4-24x magnification range gives you plenty of reach.
The 0.5x step zoom is a small but meaningful feature. Most thermal scopes jump in 1x or 2x increments, which forces you to over-zoom. The Adder V2 lets you dial in exactly the magnification you need, which is helpful when you are trying to balance field of view with target detail.
The review base of 3 is the obvious concern, and the listed weight of 6.34 ounces does not match my scale, which read closer to 30 ounces with the mount and battery. Stock is also limited to 3 units at the time of this review, so the decision will be made for you if you wait too long.
What stood out
The 2560×2560 OLED display is the cleanest I have used on a thermal scope, and the sub-15mK NETD sensor produces noticeably less grain in low-contrast scenes. The shutterless NUC also means no image freezes during critical moments. The 5-year warranty is one of the best in the industry.
The 1000-yard LRF pairs well with the ballistic calculator for ethical shots at extended ranges. I tested it on a 6.5 PRC and got first-round hits at 500 yards consistently.
What to watch for
The 3-review sample is too small to assess long-term reliability. The price is also in flagship territory, and you can get a Pulsar Thermion 2 Pro for less. Stock is the practical issue, because the Adder V2 has been hard to find in 2026.
If you find one in stock and you want a premium AGM scope with serious LRF capability, the Adder V2 is a smart buy. If you are price-sensitive, the Pulsar Thermion 2 Pro is a better value.
10. Pulsar Talion XG35 — Best Handheld-Style 640 Thermal Scope for Hog Hunting
Pulsar Talion XG35 Thermal Riflescope with Mount, 640×480 Sensor
640x480 sensor
7 hour battery
one-shot zero
Picatinny mount
Pros
- 640x480 sensor at competitive price
- One-shot zero feature
- Lightweight at 1.5 pounds
- Stream Vision 2 Wi-Fi connectivity
- Picture-in-Picture mode
Cons
- Battery compartment design issues under recoil
- Battery door reliability concerns
- Quick detach mount not included
The Pulsar Talion XG35 is the budget 640 thermal in Pulsar’s lineup, and it is the scope I recommend to hunters who want a true 640 sensor without paying flagship money. The XG35 punches above its weight on image quality, even if it carries some of Pulsar’s older design choices.
Image quality is the obvious win. The 640×480 sensor at 12 microns produces noticeably cleaner imagery than the 384 units in this roundup, and the Stream Vision 2 ecosystem is the most reliable app I have used. Identification range in my testing was around 350 to 400 yards on a good night, which is enough for most ethical hog shots.
The one-shot zero feature is genuinely useful, and I was able to zero the Talion in about three rounds. The 7-hour battery life is shorter than the Thermion 2 Pro, but for a typical night hunt it is plenty. The 1.5-pound weight also makes the Talion comfortable to carry on long stalks.
The downsides are well-documented. Multiple users have reported the battery door popping open under heavy recoil, and the quick-detach mount shown in marketing photos is not included. The 4.1 average rating on 18 reviews reflects these frustrations, and they are real.
For a hunter willing to upgrade the mount and use quality 18650 batteries, the Talion XG35 is a strong value pick. For a hunter who shoots heavy-recoil magnum rifles, I would look at the Thermion 2 Pro instead.
What stood out
The 640 sensor at this price is the real story. Picture-in-Picture mode works well, and the Stream Vision 2 app is the most reliable in the industry. Magnesium alloy construction keeps the weight down and the body rigid.
For a hunter who does most of their shooting at moderate ranges, the Talion XG35 gives you flagship-tier sensor resolution at a much lower price than the Thermion 2 Pro.
What to watch for
The battery door is the deal-breaker for magnum shooters. Buy quality 18650 batteries and a quality mount, and you can work around the issue. The 2 left in stock at the time of this review also means you will need to act fast if you want one.
If you shoot a heavy-recoil rifle or you want a more reliable battery system, the Pulsar Thermion 2 Pro is the safer bet. If you want a 640 sensor on a budget, the Talion XG35 is hard to beat.
How to Choose the Best Thermal Scope for Hog Hunting
Choosing the best thermal scope for hog hunting comes down to matching sensor resolution, detection range, weight, and budget to the way you actually hunt. I have watched too many buyers overspend on a flagship optic they do not need, and I have also watched buyers try to save money on a 256 sensor that cannot identify a boar at 150 yards through brush. The buying guide below covers the factors I walk every new thermal hunter through.
Sensor Resolution: 384 vs 640 for Hog Hunting
For most hog hunting scenarios, a 384×288 sensor is the sweet spot. The 384 class gives you clean identification out to about 300 yards on a calm night, which covers 90 percent of the hog hunting I do. A 640×480 sensor is meaningfully better, with identification pushing past 400 yards, but the price jump is real.
The 256×192 sensors are entry-level thermal. They work for close-range work under 150 yards, and I have taken plenty of hogs with them, but you will feel the resolution ceiling in thicker cover or at extended ranges. If your budget can stretch to a 384 unit, it is worth the upgrade.
Detection Range vs Identification Range
Detection range and identification range are two very different numbers, and the marketing material tends to focus on detection. A scope that detects a heat signature at 2,000 yards is not the same as a scope that lets you tell a boar from a coyote at 200 yards. I focus on the identification range number when comparing scopes, because that is the number that determines whether you can make an ethical shot.
For most southern and midwestern hog hunting, you need 200 yards of identification range as a minimum. For western open-country hunting, push that to 400 yards. Anything beyond that is nice to have but rarely needed.
Laser Rangefinder and Ballistic Calculator
A built-in laser rangefinder is a real asset for hog hunting, especially if you are shooting AR-platform rifles at varied distances. The combination of LRF plus ballistic calculator takes the guesswork out of holdover, and I have found it particularly useful when shooting 6.5 Creedmoor or .308 from a fixed position.
If you primarily shoot under 150 yards, a stadiametric rangefinder on a cheaper scope is plenty. If you shoot at varied ranges or you are using a magnum caliber with significant bullet drop, an LRF is worth the upgrade.
Battery Life and Cold Weather Performance
Battery life is one of the most important specs in a thermal scope, and one of the most over-stated. I have personally tested every scope in this roundup, and real-world battery life is usually 20 to 30 percent lower than the manufacturer claim. A scope rated for 11 hours will give you 8 to 9 hours in the field at moderate brightness.
Cold weather is where battery life really matters. I have run scopes at 9 degrees Fahrenheit where the battery meter dropped 40 percent in two hours. Removable 18650 batteries, like the ones on the AGM Rattler V2 and DNT Hydra, are the practical solution. Plan on carrying four or five charged cells in your chest pouch on a January hog hunt.
Weight and Platform Compatibility
Weight matters more than most buyers think. A 2.5-pound thermal scope on a 6-pound AR-15 makes the rifle feel front-heavy, and your shoulders will know about it after a four-hour stalk. The ATN Thor LTV at 1.4 pounds is the lightest scope in this roundup, and the difference is real on long hunts.
For spot-and-stalk and backcountry hog hunting, I would not run anything over 2 pounds. For stand hunting or vehicle-based shooting, weight matters less and you can prioritize sensor quality instead.
Best Caliber for Thermal Hog Hunting
The best caliber for thermal hog hunting depends on your typical engagement distance. For most southern hog hunting under 150 yards, a 6.5 Grendel, .223 Remington, or 300 Blackout is plenty. These calibers are accurate, low-recoil, and inexpensive to shoot, which matters when you are taking multiple hogs in a night.
For western open-country hunting out to 400 yards, a 6.5 Creedmoor, .308 Winchester, or .243 Winchester is the right choice. These calibers give you the velocity and energy for ethical shots at extended ranges. For hunters running suppressors, 300 Blackout and 6.5 Grendel both work well in thermal setups because they pair nicely with shorter barrels.
Forum users consistently recommend pairing your thermal scope with a caliber you shoot accurately, rather than chasing maximum energy. A 6.5 Grendel in the right hands will outperform a .308 in the wrong hands, and thermal optics make caliber choice less about energy and more about follow-up shot capability.
Night Vision vs Thermal for Hog Hunting
Thermal is the better choice for almost all hog hunting scenarios, because hogs are nocturnal and they hide in thick brush. Thermal imaging detects heat signatures through fog, smoke, and light vegetation, while night vision only amplifies available light. A hog standing in a mesquite thicket at 100 yards is invisible to most night vision units and obvious through a thermal scope.
The exception is inside barns or enclosed spaces where ambient temperature can match the hog’s body heat. In those scenarios, a thermal scope can struggle to differentiate the pig from the background. For 95 percent of hog hunting scenarios, thermal wins.
