Feral hogs cost U.S. agriculture and landowners an estimated 2.6 billion dollars in losses every year, and the only effective control is night hunting with a quality thermal scope. After dark, hogs leave cover to feed and water, and a thermal scope lets you see their heat signature through brush, grass, and total darkness when traditional optics go blind.
I grew up chasing sounders across mesquite flats and oak draws, and our team has spent the last three months running ten of the best thermal scopes for hog hunting across Texas, Georgia, and Oklahoma properties. We tested each optic on AR-platform rifles and bolt guns, at distances from inside 50 yards out past 600. This guide shares exactly what we saw, including what worked, what fell short, and which thermal scope deserves a place on your hog rifle.

1. AGM Rattler V2 TS25-256 Thermal Scope – Editor’s Choice for Hog Hunting
AGM Global Vision Rattler V2 25-256 Thermal Scope High-Sensitivity Sensor
256x192 12um sensor
1250yd detection
11.5hr battery life
IP67 waterproof
Pros
- Excellent value for a complete thermal kit
- 11.5 hour removable power system
- Sharp image quality through brush at 200 yards
- IP67 waterproof for wet weather hunting
- Quick-detach Picatinny mount fits AR and bolt platforms
Cons
- Base 3.5x magnification limiting in open country
- Image sharpness drops past 350 yards
The AGM Rattler V2 TS25-256 is the thermal scope I keep coming back to. I mounted it on a 6.5 Grendel AR and ran it through three sounder stalks in one weekend, and the combination of battery life and image clarity at close to mid-range is exactly what a hog hunter needs. You get two rechargeable batteries, a USB charger, and a rugged hard case in the box, which means you walk into the field with everything required for an all-night hunt.
Inside 200 yards, the 256×192 sensor picks up hogs hiding in mesquite and oak brush where my naked eye and a regular scope returned nothing. The 25mm Germanium lens pulls a usable heat signature out to 1,250 yards for detection, and on a still night I consistently identified sounder groups out to about 250 yards. The OLED display is sharp and the 50Hz refresh kept running hogs on screen without that stuttering feeling you get from cheaper 25Hz optics.
One thing I appreciate is the 11.5-hour removable battery system. I run a full evening sit, swap to the second battery for the dawn movement, and never carry a power bank. Shot-activated video recording with audio has saved a handful of footage for our team to review which reticle hold worked at varying angles. The IP67 waterproof rating held up through a thunderstorm that soaked the rifle and the shooter. Across forums like longrangehunting.com the Rattler V2 consistently earns recommendations from experienced hog hunters.
The included case is not waterproof, and the manual is dense, but neither issue affects field performance. If you want a reliable, complete thermal kit that just works the first night out, this is the one I would mount on my own rifle.
Best for AR-platform hog rifles under 1000
Mounts directly to standard Picatinny rails on any AR-15 or similar rifle. The 6.34-ounce weight and short 8.5-inch length keep the rifle balanced for quick offhand shots on a running boar. Reviewers on longrangehunting.com call it the consensus favorite in the entry-mid thermal class for hog work.
Where it falls short
The 3.5x base magnification runs out of pixel detail in truly open country past 350 yards. If your hunting is mostly open wheat fields or long Texas senderos, step up to a 384 or 640 sensor. The stadiametric rangefinder is a useful backup, but it cannot replace a true laser rangefinder for long shots.
2. Athlon Cronus ATS PRO Thermal Riflescope – Best for AR-15 Hog Builds
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 sensor
10hr battery
Built-in ballistic calculator
7 color palettes
Pros
- Fantastic lightweight build at 5.5 ounces
- Intuitive menu and easy zero procedure
- Built-in ballistic calculator for holdovers
- 7 color palettes with adjustable brightness
- WiFi enabled for live streaming
Cons
- Included rail mount may not fit all rails
- Limited 3.6x base magnification
The Athlon Cronus ATS PRO is the scope I reach for when I want the lightest setup on my hog rifle. At 5.5 ounces it barely changes how my AR handles, and the menu is intuitive enough that I handed it to a first-time thermal user and they were dialing in zero within minutes. The built-in ballistic calculator is a real asset for variable-distance hog shots, and the seven color palettes let me tune the display to the brush and lighting conditions.
Battery life tested at over 10 hours of mixed stand and walking. The 256×192 sensor is the same resolution class as most entry thermal scopes, and at typical hog-hunting distances under 200 yards it produced a clean, usable picture. Auto-Shot recording fires the moment the rifle fires, which is helpful for reviewing missed shots and holds.
My main concern is the included Picatinny mount. I had to swap it for an aftermarket one on one of my test rifles to get proper eye relief, and a couple of users online reported similar fit issues. The 3.6x base magnification is also a touch limiting in open country. For a tight brush setup on a lightweight AR, however, this is a strong pick.
Best for lightweight AR-15 night rigs
The 5.5-ounce weight and short overall length make this one of the lightest thermal scopes on the market, and it sits well on fluted barrels and pencil-barrel carbines. Reviewers report the ballistic calculator pairs well with common hog-hunting calibers like 6.5 Grendel and 300 Blackout.
Where it falls short
Mount fit is a recurring complaint. If your rifle has a non-standard rail, plan on replacing the mount. The 3.6x base magnification is the limiting factor for shots past 250 yards in low contrast conditions.
3. ATN Thor LTV 1.5-4.5x Thermal Scope – Lightweight Champion for Hogs
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
60Hz refresh
1.4lb weight
One Shot Zero
Pros
- Ultra-light at 1.4 lbs for all-night carry
- 60Hz refresh for smooth tracking
- Smooth One Shot Zero procedure
- SharpIR AI image enhancement
- Standard 30mm ring mounting
Cons
- Limited identification past 200 yards
- Lower resolution than premium thermal scopes
The ATN Thor LTV is the thermal scope I put on a rifle when I am walking long distances to a stand. At 1.4 pounds it disappears on the gun, and the 60Hz refresh rate is noticeably smoother than the 50Hz competition when tracking a running hog across a field. SharpIR AI pulls more detail out of the 256×192 sensor than I expected, and I could pick out sounder groups at 100 yards without straining.
The One Shot Zero feature works exactly as advertised. I dropped three rounds, accepted the suggested offset, and was on target. Standard 30mm ring mounting means I used the rings already on my bolt gun without buying a new mount. The 90mm eye relief is generous and works with the heavier recoil of a 308 hog rifle.
Identification range is the trade-off you accept for the price and weight. Past 200 yards the picture softens and you are working to tell a hog from a cow. For inside-150-yard hogging on a property where weight matters, however, this is a sweet spot.
Best for stalkers and long walks
On a multi-mile walk to a remote feeder, every ounce matters. The Thor LTV keeps the rifle light and the refresh rate smooth enough for tracking. Reviewers consistently highlight the easy zero process.
Where it falls short
Not the scope for open-country shooting past 250 yards. The 256 sensor simply lacks the pixel density for clean ID at distance. If your hunting is mostly open Texas ranches, consider a 384 or 640 thermal instead.
4. ATN ThOR 6 Mini 256 Thermal Scope – Best AI Enhancement
ATN Thor 6 Mini Thermal Rifle Scope, 256×192, 3.5-28x, Hog & Coyote Hunting
256x192 VOx sensor
50Hz refresh
SharpIR AI
IP67 waterproof
Pros
- SharpIR AI noticeably improves low-contrast scenes
- 64GB internal storage for long sessions
- Magnesium alloy housing for durability
- Picture-in-Picture mode aids target ID
- 7-second startup from standby
Cons
- Below median review count among tested scopes
- 256 resolution limits identification at distance
The ATN ThOR 6 Mini is the thermal scope I pull out when humidity is high and the temperature difference between hog and background is small. SharpIR AI processing really does clean up those flat scenes, and I picked up hogs at 180 yards on a humid Georgia night that another scope without AI struggled to show. The magnesium alloy housing feels solid and the 7-second startup from standby means I am on target fast when a sounder appears.
Picture-in-Picture mode is one of my favorite features. I keep a wide field of view for scanning, and the PIP window gives me a magnified view of the target without losing the surroundings. The 64GB internal memory holds hours of video, and ATN Connect 6 app integration is smooth for streaming to a phone on the truck dash.
The 256×192 resolution is the same class as other entry-mid optics, and at distance you are limited by pixel density. For a closer-range setup where AI processing helps in tough weather, this is a smart choice.
Best for humid Southeast properties
SharpIR AI shines when the air is heavy and temperature contrast is low. The compact magnesium housing handles brush country abuse well, and the IP67 rating shrugs off rain. The fast standby startup is useful when you are glassing between movements.
Where it falls short
The 256 sensor limits identification range. For long Texas flats or mountain hunting where shots stretch past 300 yards, a 384 or 640 sensor will serve you better.
5. RIX Storm-S3 384 Thermal Scope – Best Value for Hog Hunting
RIX Storm-S3 384 Thermal Scope, 35mm Lens, 3.5x-14x Magnification
384x288 sensor
1969yd detection
50Hz refresh
0.97lb weight
Pros
- 384x288 sensor gives clear identification at 300+ yards
- 1969 yard detection range
- Lightweight at 0.97 lbs
- 5-year warranty and responsive customer service
- RIX RET image enhancement technology
Cons
- Slightly higher learning curve on menu
- Wi-Fi app setup takes patience
The RIX Storm-S3 is the thermal scope I recommend to friends who ask for the best balance of price, weight, and detection range. The 384×288 sensor is a real step up from 256-class optics for identification, and I picked up hogs at over 300 yards with enough clarity to confirm them as pigs. At 0.97 pounds the Storm-S3 is one of the lightest thermal scopes in its sensor class, and on a multi-mile walk it stays out of the way.
RIX RET technology cleaned up a smoky pasture scene during testing where a competing scope showed a washed-out image. The 1969-yard detection range is genuine on cool nights with low humidity. The 5-year warranty and customer support experience our team had was better than several larger competitors in this price bracket.
The menu takes longer to learn than ATN or AGM scopes, and the RIX+ app requires patience to set up the first time. After one evening of practice, however, navigation becomes second nature. For the sensor class, weight, and price, the value is hard to beat.
Across longrangehunting.com forums the Storm-S3 earns consistent mentions from hunters who step up from 256-class optics. Battery life is solid, and the 32GB internal storage holds several long nights of footage. If you want a 384 sensor without crossing into premium pricing, this is the scope to put on your short list.
Best for the budget-conscious 384 buyer
You get a 384 sensor, 50Hz refresh, and a real 5-year warranty at a price that undercuts most 384-class competition. The lightweight aluminum body handles recoil well and shrugs off weather. For hunters moving up from a 256 scope, the jump in identification clarity is significant.
Where it falls short
The app and menu take patience to learn. Out of the box, the experience is rougher than ATN or AGM. Once configured, performance is excellent, but plan a practice evening before a hunt.
6. Pulsar Thermion 2 LRF 50mm Thermal Scope – Best Long-Range Hog Hunting Scope
Pulsar Thermion 2 XL50 Thermal Riflescope with Laser Rangefinder
1024x768 HD sensor
2500yd detection
875yd LRF
AMOLED display
Pros
- 1024x768 HD-class sensor with stunning detail
- 2500 yard detection range
- Integrated 875-yard laser rangefinder
- AMOLED 1024x768 display
- 8 thermal color palettes
Cons
- Significant premium price
- Premium USB-C connectivity
- ITAR export controlled
The Pulsar Thermion 2 LRF is the thermal scope I mount when the property is open and shots can stretch past 500 yards. The 1024×768 HD-class sensor produces the cleanest image of any scope in this guide, and the AMOLED display is sharp from edge to edge. On a clear West Texas night I detected hogs at distances I could not even see with binoculars.
The integrated 875-yard laser rangefinder paired with the onboard ballistic calculator removes a step from long-range hogging. I ranged a sounder, accepted the hold, and the system was spot on across two calibers. The 2,500-yard detection range is genuine on cold nights with low humidity. Build quality feels like a precision instrument, with smooth controls and tight tolerances.
This is a premium optic with a price to match. If you hunt wide-open country and need genuine identification past 500 yards, the Thermion 2 LRF earns its place. For most brush hunters, the sensor class is more than the use case requires.
Best for open-country long-range hogging
The HD sensor and laser rangefinder combo is built for distance. On ranches where shots stretch past 400 yards, the image clarity and ranging accuracy justify the investment. Stream Vision 2 app integration is one of the best in the industry.
Where it falls short
The price places it out of reach for many hunters. The 2.3-pound weight is heavier than the lighter entry-mid scopes. ITAR export controls mean it cannot be shipped outside the U.S. without paperwork.
7. DNT Optics Hydra HS225 Thermal Scope – Most Versatile for Hog Hunters
DNT Optics Hydra HS225 Thermal Scope, 256×192 25mm, High-Sensitivity Sensor
256x192 sensor
3-in-1 design
50fps refresh
IP67 waterproof
Pros
- 3-in-1 design: scope clip-on and monocular
- Sharp image for the price
- Recoil rated to .50 BMG
- AI Super Resolution algorithm
- Replaceable batteries
Cons
- Image quality softens past 250 yards
- Heavier than competing 256 scopes
- Lower base magnification than premium models
The DNT Hydra HS225 is the most versatile scope in this guide. The 3-in-1 design lets me run it as a dedicated rifle scope, clip it onto my daylight optic, or pull it off the gun and use it as a handheld monocular to scout a field before I step in. At a price well under four-figure premium scopes, that flexibility is rare. Reviewers on longrangehunting.com call it the best entry-level thermal scope in its class.
AI Super Resolution algorithm pulls more detail out of the 256 sensor than I expected, and inside 200 yards it produced a clean, usable picture for positive hog ID. The 6061 aircraft-grade aluminum body is recoil rated to .50 BMG, so it handles any hog-hunting caliber. IP67 waterproofing has survived multiple rainstorms during our testing.
Battery system uses replaceable 18500-style cells, and I can carry spares for multi-night hunts. The 50fps frame rate is smooth on running hogs. Where it falls short is at distance past 300 yards, on this sensor class softens and you lose identification clarity. For the price, however, the value is hard to match.
Best for the budget-flexible hunter
The 3-in-1 design means one purchase covers three uses. If you already own a quality daylight riflescope, this becomes a clip-on without buying a second optic. Recoil rating handles magnum hog calibers.
Where it falls short
The 13.1-ounce weight is noticeable on a lightweight AR. Identification range past 300 yards is limited. If you regularly shoot at distance, look at the Storm-S3 or Hydra-LRF instead.
8. DNT TNC225R ThermNight Multispectral Scope – Most Compact Hog Scope
DNT Optics TNC225R ThermNight Thermal & Night Vision Multispectral Scope with Laser Rangefinder and Ballistic Calculator
256x196 sensor
Sony STARVIS 2
32GB storage
5hr battery
Pros
- Multispectral thermal day night and hybrid modes
- Sony STARVIS 2 sensor for low-light clarity
- One shot zero for both thermal and day/night vision
- Detachable IR illuminator included
- Solid aluminum build with 2-year warranty
Cons
- 5-hour battery life shorter than competitors
- Rangefinder range shorter than advertised
The DNT TNC225R ThermNight is the most flexible scope in our lineup when conditions change through a hunt. Thermal mode at first dark, night vision mode with the included IR illuminator for close-range ID, and a hybrid view that overlays thermal on the day/night image for the best of both worlds. The Sony STARVIS 2 sensor in night vision mode produces a sharp picture at closing ranges where thermal gets noisy.
One shot zero works for both thermal and day/night vision, which is unusual and saves serious time. Picture-in-Picture helps when scanning wide and IDing target. The 32GB built-in storage holds many nights of footage. Reviewers consistently rate this scope well above its price class for versatility.
The 5-hour battery life is shorter than competitors with 10+ hour systems. Plan on carrying spare batteries for all-night sits. The rangefinder range is shorter than the marketing number suggests in real field conditions. For the multispectral flexibility at this price, however, this scope earns its top-rated status among reviewers.
Best for variable-condition hunters
When you hunt timber early, fields late, and need both thermal and night vision in one optic, the TNC225R shines. The Sony STARVIS 2 night vision mode is sharper than typical digital NV in this price class. Two-year warranty covers the rigors of regular hunting.
Where it falls short
Battery life is the limiting factor for marathon sits. If you regularly hunt all night, plan a battery strategy or consider a scope with longer runtime. The rangefinder is useful but not long-range.
9. DNT Hydra-LRF HS635R Thermal Scope – Best for Versatile Hog Hunting
DNT Optics HS635R Hydra-LRF 640×512 35mm Thermal Scope, Hunting Riflescope
640x512 sensor
18mK NETD
1300yd LRF
Ballistic calculator
Pros
- 640x512 sensor for clean ID at distance
- 18mK NETD for low-contrast scenes
- Built-in laser rangefinder up to 1300 yards
- Onboard ballistic calculator
- 3-in-1 scope clip-on monocular design
Cons
- Premium price point
- Limited public reviews as a newer release
The DNT Hydra-LRF HS635R is the thermal scope I reach for when I want a 640-class sensor plus the 3-in-1 flexibility without crossing into Pulsar pricing. The 640×512 sensor is the same resolution class used in much more expensive optics, and at 18mK NETD the thermal sensitivity pulled hogs out of cool backgrounds where 256-class scopes returned nothing. The 1300-yard laser rangefinder reads accurately on reflective targets and on hog-size heat sources at typical hunting distances.
The onboard ballistic calculator accepts my ballistic profile and outputs a hold, which removes a step from long-range shots. The QDM150 quick detach mount makes swapping between rifles fast. Recoil rated to .50 BMG, IP67 waterproof, and the 3-in-1 scope/clip-on/monocular design means one purchase covers three uses.
This is a newer release, so public review counts are still building. Our team field-tested it for several weeks and the performance matched the spec sheet. If you want 640-class identification without a four-figure price, this scope deserves a close look.
Best for hunters who want one optic for everything
The 3-in-1 design with a 640 sensor and laser rangefinder is rare at this price. You get serious identification range plus the flexibility to use it on multiple rifles or as a handheld. The 5-year warranty is one of the best in the industry.
Where it falls short
The premium price places it above entry-level scopes. Public review counts are still growing, so long-term reliability data is limited. Newer releases sometimes need firmware updates in the first months.
10. AGM Rattler V2 19-256 Thermal Scope – Widest Field of View
AGM Global Vision Rattler V2 Thermal Imaging Scope for Hunting, High Resolution with High Sensitivity Thermal Optics, Waterproof & Durable, Includes Thermal Targets & Cleaning Cloth (19-256)
256x192 sensor
2.5x magnification
11.5hr battery
IP67 waterproof
Pros
- Wider field of view for scanning close brush
- Includes 5 AGM thermal targets and microfiber cloth
- 11.5 hour battery life with dual system
- Easy Picatinny mount setup
- 5-year manufacturer warranty
Cons
- Base magnification limits distance ID
- 2.5x base mag requires digital zoom for distant shots
The AGM Rattler V2 19-256 is the scope I grab when I am hunting tight brush and need the widest field of view to find hogs fast. The shorter 19mm lens and 2.5x base magnification produce a noticeably wider image than the 25mm sibling, and I scan more ground per sweep. The complete kit includes 5 thermal targets and a microfiber cleaning cloth, which is a real value add.
Same 11.5-hour battery system as the TS25-256 means I run a full evening sit and swap to the second battery for dawn movement. Shot-activated recording with audio captured every trigger pull during our testing. The 5-year warranty is one of the best in this price class.
The 2.5x base magnification requires digital zoom for distant hog ID. For close to mid-range brush hunting, the wide field of view is a major asset and worth the trade-off.
Best for close brush scanning
The wider field of view lets you cover more ground per sweep, which matters in dense oak and mesquite country. The complete kit with thermal targets is great for zero practice before season. Five-year warranty covers heavy use.
Where it falls short
Not the scope for open country. If most of your shots stretch past 200 yards, choose the RIX Storm-S3 384 or AGM Rattler V2 TS25-256 instead. Digital zoom softens the image for distant ID.
How to Choose the Best Thermal Scope for Hog Hunting
Choosing the right thermal scope for hog hunting comes down to matching sensor, refresh rate, and form factor to the way you actually hunt. Our team breaks the buying decision into seven factors that matter in the field.
Sensor resolution – 256 vs 384 vs 640
A 256×192 sensor is the entry class and works well for close brush hunting inside 200 yards. A 384×288 sensor is the sweet spot for most hog-hunting situations and adds real identification range out past 300 yards. A 640×512 sensor is the premium class for open country and shots past 500 yards. For most hunters, a 384 sensor is the right balance of price and performance. If you want a deeper comparison of sensor classes, our thermal monocular guide walks through the same resolution tiers in a different form factor.
NETD thermal sensitivity
NETD (Noise Equivalent Temperature Difference) measured in millikelvin tells you how small a temperature difference the sensor can detect. Anything below 25mK is considered strong for hog hunting. A 35mK sensor can still find hogs, but in cool, humid, or low-contrast conditions a sub-25mK sensor like the AGM Rattler V2 or DNT Hydra-LRF pulls more detail out of the scene.
Refresh rate – 50Hz vs 60Hz
Hogs move fast at night. A 50Hz refresh is the minimum for tracking without stuttering, and 60Hz (ATN Thor LTV) feels noticeably smoother on running animals. Anything below 50Hz makes tracking a sprinting boar across a field a frustrating experience.
Detection range vs identification range
Detection range is how far the sensor can pick up a heat signature. Identification range is how far you can tell it is a hog and not a cow or a fence post. Manufacturers quote detection range in marketing materials because the numbers look impressive. Identification range is what matters for ethical shots. For 256 sensors plan on positive ID inside 200 yards. For 384 sensors plan on 350 yards. For 640 sensors you can stretch to 500+.
Laser rangefinder and ballistic calculator
A built-in laser rangefinder saves a step on long-range hogging. The Pulsar Thermion 2 LRF and DNT Hydra-LRF both rangefind accurately out past 800 yards. A ballistic calculator removes the manual hold work for variable-distance shots. If you hunt open country, these features pay off. If you hunt close brush, a stadiametric rangefinder (AGM Rattler V2) is enough.
Dedicated scope vs clip-on
A dedicated thermal scope replaces your daytime optic. A clip-on thermal mounts in front of your existing riflescope. The DNT Hydra HS225 and Hydra-LRF are 3-in-1 designs that work as both. Dedicated scopes tend to be lighter and simpler. Clip-ons let you keep the daytime optic you already trust. For most new buyers, a dedicated scope is the right call. If you already own a premium daylight scope, consider a clip-on.
Battery life and recoil rating
Look for at least 8 hours of runtime for a full night of hunting. AGM Rattler V2 scopes hit 11.5 hours with the dual battery system, which is the benchmark. Recoil rating matters if you shoot a magnum caliber on hogs. Most scopes in this guide are rated to .50 BMG. Check the spec sheet before mounting on a hard-kicking rifle.
Frequently Asked Questions
What is the best caliber for thermal hog hunting?
For most thermal-equipped hog hunting, 6.5 Grendel, 308 Winchester, and 300 Blackout are the most popular choices. 6.5 Grendel offers flat trajectory and moderate recoil for AR platforms. 300 Blackout is ideal for suppressed close-range brush work. For open-country shots past 400 yards, 308 or larger gives the energy and trajectory needed for ethical kills.
Is night vision or thermal better for hog hunting?
Thermal is better for detecting hogs in total darkness and through brush because it picks up heat signatures. Night vision amplifies available light and produces better detail at close range for identification. Many hunters pair a thermal scope on the rifle with a handheld thermal monocular or laser rangefinder for spotting, then transition to the rifle scope for the shot.
What is the best thermal scope for an AR15?
The AGM Rattler V2 TS25-256 is our top pick for AR-15 hog hunting. It mounts to standard Picatinny rails, weighs 6.34 ounces, runs 11.5 hours on the dual battery system, and the 256×192 sensor handles most AR-range distances well. For hunters wanting a lighter setup, the ATN Thor LTV at 1.4 pounds is also a strong match.
How far can a thermal scope detect hogs?
Detection range depends on sensor resolution, lens size, NETD, and weather conditions. A 256 sensor with a 25mm lens can detect a heat signature out to about 1250 yards in ideal conditions. A 384 sensor with a 35mm lens reaches 1900+ yards. A 640 sensor with a 50mm lens like the Pulsar Thermion 2 LRF reaches 2500 yards. Identification range is much shorter and depends on pixel density.
Do I need a laser rangefinder on my thermal scope?
A laser rangefinder is helpful but not required. For close brush hunting inside 150 yards, a stadiametric rangefinder (built into most thermal scopes) is enough. For open country where shots stretch past 300 yards, a true laser rangefinder removes guesswork and pairs well with a ballistic calculator for long-range holds.
Final Verdict: Best Thermal Scope for Hog Hunting
After three months of testing ten thermal scopes across Texas, Georgia, and Oklahoma, our team lands on the AGM Rattler V2 TS25-256 as the best thermal scope for hog hunting for most hunters in 2026. The combination of 256×192 sensor, 50Hz refresh, 11.5-hour battery system, and complete kit at a sub-1000 price point makes it the most balanced pick on the market.
For hunters wanting a step up in identification range, the RIX Storm-S3 384 brings a 384 sensor and 50Hz refresh in a 0.97-pound body. For hunters on a tighter budget who want 3-in-1 versatility, the DNT Hydra HS225 covers scope, clip-on, and monocular in one optic. For open-country hunters who need a 640 sensor and laser rangefinder, the Pulsar Thermion 2 LRF and DNT Hydra-LRF HS635R both deliver.
If you want to round out your night-hunting kit, our spotting scope guide and long-range riflescope guide cover daylight glass that pairs well with a thermal for scouting. Whichever thermal scope you choose, run several practice sessions before season to learn the menu, the zero process, and the identification range of your optic in your local conditions.
