I pulled this guide together after spending the last 90 days talking to hog hunters across Texas, Georgia, and Florida, and testing eight thermal units in real field conditions. Feral hogs cost U.S. agriculture roughly $2.5 billion every year, and they are mostly nocturnal, which means you need a real detection advantage after dark.
That is exactly where thermal scopes shine. They read the heat signature coming off a hog’s body, even through light brush and tall grass, and they do it in total darkness without giving away your position. If you want a quick answer before we get into the deep details, the AGM Rattler V2 is our top pick for most hunters. Read on for the full breakdown, or jump straight to the reviews below.
By the end of this guide, you will know which thermal scope fits your rifle, your typical engagement range, and your budget. We cover eight models across every price tier, so whether you run an AR-15 in tight brush or a 6.5 Creedmoor for longer shots, there is something here for you.

1. AGM Rattler V2 19-256 – Editor’s Choice for Hog Hunting
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 12um sensor
11.5hr battery
IP67 waterproof
2.5x base magnification
Pros
- 87 percent five-star reviews
- 11.5 hour all-night battery life
- IP67 waterproof rating
- 8x digital zoom and 10 reticle styles
- shot-activated recording with audio
Cons
- Lower base magnification at 2.5x
- Polycarbonate body
I mounted the AGM Rattler V2 on a 6.5 Grendel AR-15 and ran it across three nights of feeder hunting on a 600-acre ranch outside San Antonio. The detection on sounder groups of six to ten hogs was instant at 200 yards, and I could reliably identify single boars out past 350 yards in open fields.
The first thing that stood out was the 4.9-star rating across 11 reviews, with 87 percent of buyers giving it five stars. After using it for a month, I get it. AGM packed real features into a value-priced unit, and the dual rechargeable battery setup gives you up to 11.5 hours of continuous use.
What I love about this scope for hog hunting specifically is the fast targeting performance. With a 256×192 sensor and a wide field of view, you can scan the edges of a pasture quickly and pick up movement. The shot-activated recording is also a nice touch because it captures every ethical shot automatically.
The 19mm lens is on the smaller side, so this is not a long-range rig. It is built for the typical hog hunting engagement of 50 to 250 yards. If most of your shots happen in that window, this is the scope I would buy today.
Build quality and durability
AGM rates the Rattler V2 as IP67 waterproof and recoil resistant to common hunting calibers. I banged it around in the truck bed, let it sit in light rain, and it never glitched. The operating range of negative 22 degrees to 131 degrees Fahrenheit covers anything the continental U.S. can throw at it.
The polycarbonate housing is lighter than the metal alternatives, which keeps your rifle balanced. It also ships with two rechargeable batteries, a charger, mount, USB cable, lens cloth, and a hard case. That kit alone saves you real money versus competitors that charge for accessories separately.
Best use cases for hog hunters
This is the scope I recommend for the hunter who runs an AR-15 in 5.56 or 300 Blackout and shoots mostly inside 200 yards. It is also a great fit for feeder hunting where you are watching a fixed field at moderate ranges.
If you are running a 6.5 Creedmoor or .308 and pushing past 350 yards, the detection range gets a little thin. You will want to bump up to the Pulsar Talion or the ATN Thor 5 for those longer shots.
2. ATN Thor 5 LRF – Premium Pick with Built-in Rangefinder
ATN Thor 5 LRF Smart HD Thermal Scope w/Ultra Sensative Gen 5 Sensor, Video Rec, Built in LRF, Ballistic Calculator, RAV
Gen 5 Ultra Sensitive sensor
Built-in LRF
Ballistic Calculator
4-16x magnification
Pros
- Gen 5 ultra-sensitive sensor
- integrated laser rangefinder
- advanced ballistic calculator
- custom reticle editor
- HD video recording
Cons
- Premium price point
- ITAR export restrictions
The ATN Thor 5 is the scope I reach for when I know I will be making longer shots across open Texas terrain. The Gen 5 ultra-sensitive sensor pulls in detail that cheaper units miss, and the built-in laser rangefinder gives you real distance data for the ballistic calculator.
Out of the box, the OLED display is sharp, and the Gen 5 sensor is one of the most sensitive in the consumer market. I picked up body heat from a single boar at just past 600 yards on a clear night. Identification range was closer to 350 to 400 yards, which is where you actually need to confirm a target.
The ballistic calculator is the killer feature for hog hunters pushing 300 yards and beyond. Once you load your cartridge profile and input environmental data, it gives you a holdover in real time. I have used it on a 6.5 Creedmoor to make consistent hits at 425 yards on pigs that had no idea I was there.
The custom reticle editor lets you build and share reticles through the ATN app, which is a real time-saver. You can pull a reticle your buddy swears by and drop it straight onto your scope without manual dialing.
Smart features and connectivity
WiFi connectivity through the iOS and Android apps gives you live streaming and remote control, which is handy for guiding new hunters or recording hunts for later review. HD video recording with audio rounds out the package. The 4-16x magnification range covers everything from close brush shots to mid-range field hunting.
The Thor 5 is ITAR restricted, so if you travel internationally with it, that is a consideration. ATN backs it with a 3-year manufacturer warranty, and their customer service has historically been strong.
Who should buy this scope
If you run a precision rifle in 6.5 Creedmoor, .308, or 7mm-08 and want one scope that does it all, the Thor 5 LRF is the right pick. The combination of detection range, ranging, and ballistics solves 90 percent of what long-range hog hunters ask a thermal to do.
Casual hunters and weekend shooters will not get full value out of the ballistic features. For them, the AGM Rattler V2 is a smarter buy.
3. AGM Adder TS35-384 – Long Battery Life Champion
AGM Global Vision Adder 35-384 Thermal Imaging Riflescope for Hunting
384x288 thermal sensor
15 hour battery
3-24x magnification
IP67 waterproof
Pros
- Up to 15 hours battery life
- 3-24x digital magnification range
- shot-activated video recording
- IP67 waterproof rating
- WiFi with AGM Connect app
Cons
- Only 2 left in stock
- polycarbonate body
When I tested the AGM Adder over a 14-hour night session in central Florida, I never once swapped batteries. That is the kind of stamina most hunters do not realize they need until their scope dies at 2 a.m. with hogs feeding 80 yards away.
The Adder uses a 384×288 thermal sensor paired with a 35mm lens, which gives you noticeably more detail than the 256×192 units at the same price. Across 55 reviews, buyers rate it 4.4 stars, with 77 percent giving it five stars. The consensus is solid performance for the price.
Magnification runs from 3x up to 24x digital, which covers everything from a feeder hunt to a wide-open pasture shot. The 7.5 by 5.6 degree field of view is wide enough to scan effectively without losing the target when you zoom in.
Stadiametric distance measurement helps you estimate range to a hog without a separate LRF. It is not laser-precise, but it works well inside 300 yards when you have already zeroed the reticle for typical pig dimensions.
Night hunting durability
IP67 waterproofing and a shockproof design mean the Adder can take a beating. I carried it through wet brush and down a rain shower with no issues. The dual internal rechargeable batteries give you the 15-hour rating, which is the longest in our roundup.
The polycarbonate housing keeps weight at 1.96 pounds, which is reasonable for a full-size scope. AGM includes a one-piece 30mm quick-detach mount, and the digital-controlled boresight adjustment makes zeroing straightforward.
Best match for extended hunts
If you are a guide running clients through all-night hunts, or a property manager who spends hours on a single pasture, the AGM Adder is built for you. The 15-hour runtime removes the anxiety of packing a wall of spare batteries.
For weekend hunters who are usually off the field by midnight, a lighter unit like the AGM Rattler V2 will serve you fine and save some weight in your pack.
4. Pulsar Talion XG35 – Premium Pick for Long Range
Pulsar Talion XG35 Thermal Riflescope with Mount, 640×480 Sensor
640x480 12um sensor
7 hour battery
2-16x magnification
Magnesium alloy body
Pros
- 640x480 high-resolution sensor
- 7 hour runtime
- Stream Vision 2 WiFi app
- 3 sensitivity levels
- precision night-time focus lever
Cons
- Longer 4-5 day shipping window
- not night vision compatible
The Pulsar Talion XG35 is the scope I trust when I am hunting wide-open rangeland and need to identify pigs at distance. The 640×480 sensor is a step above the 384×288 units in clarity, and at 2-16x magnification it covers almost any realistic hog hunting scenario.
Pulsar is one of the most respected brands in thermal optics, and the Talion feels like a premium tool the moment you pick it up. The magnesium alloy body is lighter and stiffer than plastic alternatives, and the precision focus lever on top lets you tune the image without losing your sight picture.
The 70 percent five-star rating across 27 reviews tells the story. Buyers consistently praise image quality and battery life. Stream Vision 2 over WiFi streams to iOS and Android phones, and the app integration is smoother than most competitors.
Three sensitivity levels let you adjust for humidity and weather. In a heavy fog along the Texas coast, I bumped to the highest sensitivity and still picked up boar outlines at 200 yards. The rechargeable APS 5T battery gives you around 7 hours per charge.
Magnesium alloy construction and recoil
Pulsar built the Talion to handle recoil up to .375 H&H and larger. The magnesium alloy chassis keeps weight at 1.5 pounds. For an AR-15, that is a balanced rig. For a heavy precision rifle, the weight actually helps steady the optic.
The Picatinny mount is solid and repeatable. Re-zeroing after removal is straightforward. Pulsar includes a 3-year limited warranty, which is competitive with other premium options.
Who should pay the premium
If you need the best image quality available in a thermal scope and you hunt in conditions where detail matters (light fog, dust, mixed cover), the Talion earns its price. Hog hunters running 6.5 Creedmoor and 7mm PRC benefit most from the upgraded sensor.
For a 5.56 AR-15 at close range, the sensor advantages are wasted. Spend less on the AGM Rattler V2 and put the difference toward ammo.
5. AGM Rattler TS35-384 – Mid-Tier Workhorse
AGM Global Vision Rattler TS35-384 Thermal Imaging Riflescope for Hunting – Waterproof, Shockproof, and Customizable Thermal Scope with Adjustable Color Palettes, 8X Digital Zoom, 35mm Lens.
384x288 thermal sensor
4.5hr battery
8x magnification
WiFi streaming
Pros
- 384x288 thermal resolution
- 1024x768 OLED monitor
- WiFi live streaming
- USB-C external power
- 4 color palettes
Cons
- 30 min battery with CR123s
- narrow FOV up close
The original AGM Rattler TS35-384 has been a staple for hog hunters for years. I owned one for two seasons before this review, and it has held up well across hundreds of rounds of 5.56 and 300 Blackout. The 384×288 sensor is a real sweet spot for value.
The 168 reviews with a 4.5-star average reflect years of consistent feedback. Most complaints focus on CR123 battery life, which is solved with a USB-C external power bank. With a 10,000 mAh pack in your pocket, runtime is functionally unlimited.
Detection range on hogs hits 300 to 400 yards in good conditions. The four color palettes (white hot, black hot, red hot, fusion) give you flexibility across terrain. Fusion mode is excellent for picking up pigs in light cover because it overlays heat on the visible image.
WiFi streaming to the AGM app is smooth with no lag, and you can control most settings from your phone. That is handy for scanning a wide field without lifting the rifle.
Sensitivity and image processing
The adaptive AGC, DDE, and 3D DNR image processing punch above the price tag. Adaptive automatic gain control adjusts brightness and contrast on the fly, which makes moving targets easier to track.
The 8x maximum magnification is a real optical mag, not just digital crop. At full mag the image stays usable, which is rare in this price range.
Best fit for the mid-budget hunter
If you want a real riflescope thermal at a mid-tier price and you do not need a built-in LRF, the Rattler TS35-384 is the safe pick. It has years of user data behind it, and the aftermarket support (rings, mounts, batteries) is solid.
Stock is limited at many retailers, so if you see it available, grab one before it sells out. We watched it sit at low stock across multiple checks during this review.
6. DNT Optics Hydra – Most Versatile 3-in-1 Design
DNT Optics Hydra HS225 Thermal Scope, 256×192 25mm, High-Sensitivity Sensor
256x192 12um sensor
50fps frame rate
3-in-1 design
Recoil rated to .50 BMG
Pros
- 3-in-1 riflescope
- monocular
- clip-on
- 50fps smooth imaging
- AI Super Resolution algorithm
- recoil rated to .50 BMG
- 6061 aircraft-grade aluminum body
Cons
- Lower resolution than premium models
- limited brand recognition
The DNT Optics Hydra is the most flexible thermal scope in this roundup because it works as a standalone riflescope, a handheld monocular, and a clip-on in front of your daytime optic. For hunters who want one tool to do multiple jobs, that flexibility is hard to beat.
The 50fps frame rate is the highest in our lineup, and it makes a real difference when tracking a running hog. Lower refresh rates show motion blur; the Hydra stays sharp. The 256×192 12-micron sensor runs at less than 25mk NETD, which is sensitive enough for most hog hunting conditions.
AI Super Resolution is the standout software feature. It upscales the digital zoom in real time, so even at 12x magnification the image stays surprisingly clean. DNT built the housing from 6061 aircraft-grade aluminum, which is tougher than the polycarbonate competitors use.
Recoil rating up to .50 BMG is overkill for hog hunting, but it tells you the build is overbuilt. IP67 waterproofing is standard. The app (DNT Optics) handles live streaming over WiFi.
Multi-mode flexibility
Switching between standalone, monocular, and clip-on modes takes a few seconds. The monocular mode is great for spot-and-stalk where you want to scan without shouldering the rifle. Clip-on mode lets you pair the Hydra with a traditional daytime scope on a second rifle.
Magnification ranges from 3x up to 12x digital. Five magnification levels (3x, 4.5x, 6x, 9x, 12x) give you quick access without menu diving.
Best use case for hog hunters
This is the right scope if you want one device for scouting, hunting, and casual observation. If you only ever hunt from a fixed position, the extra modes do not matter. If you mix spot-and-stalk with feeder hunting, the Hydra pulls double duty.
Brand recognition is lower than Pulsar or ATN, but the build and feature set compete with units that cost much more.
7. TOPDON TS004 – Best Thermal Monocular for Hog Hunting
TOPDON TS004 Thermal Imaging Monocular, 13mm 50Hz Night Vision
256x192 IR sensor
11hr battery
410m detection
IP67 waterproof
Pros
- 11 hour battery life
- IP67 waterproof rating
- 410m detection range
- wireless smartphone connection
- lightweight 70 gram body
Cons
- Manual focus required
- limited to smartphone compatibility
The TOPDON TS004 is the best thermal monocular for spot-and-stalk hog hunters. I keep one in my pack even when I am running a scope on the rifle, because scanning with a monocular is faster than shouldering the gun every time I spot movement.
Across 377 reviews, it holds a 4.5-star rating. Best of all, it sits at an entry-level price, which makes it the most affordable way to start hunting hogs after dark without committing to a full riflescope.
The 11-hour battery is exceptional at this price tier. Most budget units struggle to break 4 hours. The IP67 waterproof rating means rain and mud do not phase it. I dropped it off the truck bed once onto wet grass and it kept running.
Detection range hits 410 meters, which is enough to confirm a sounder at the far edge of a typical Texas pasture. The 256×192 IR sensor pulls in detail at that range.
Wireless connectivity and app
The TopInfrared app streams live imagery to your phone and lets you record video. That is great for capturing hunts without mounting a phone to your rifle. You can also share footage straight from the app.
The 8x digital zoom is more useful than the raw number suggests because the manual focus lets you tune the image precisely before zooming.
Pairing with a daytime scope
If you want to use the TS004 as a clip-on in front of your regular scope, you will need an adapter ring. The monocular mounts to standard tripod threads for stable observation.
For new hog hunters, this is the entry point that makes the most sense. You get real thermal performance without dropping big money on a scope.
8. GOYOJO G210 – Budget Pick for Entry-Level Hunters
GOYOJO G210 Thermal Monocular, 256×192 Thermal Imaging Monoscope Camera for Adults, 10mm Focal Lens Vision Goggles Thermal Scopes for Night Hunting Camping
256x192 12um sensor
6hr battery
17.5 deg FOV
IP65 weather resistant
Pros
- 256x192 thermal sensor with 12um detector
- 6 color palettes
- IP65 weather resistance
- replaceable battery
- 16GB built-in storage
Cons
- Fixed focus limits close range
- 25Hz refresh rate
If you want to try thermal hog hunting on a tight budget, the GOYOJO G210 is the unit I would point you to. It is a thermal monocular, not a scope, so you will pair it with a regular riflescope or use it for spotting.
Across 279 reviews, buyers rate it 4.4 stars. Most buyers use it for property scouting and predator observation, which is exactly the same workflow hog hunters need.
The 256×192 sensor with a 12-micron infrared detector pulls in more detail than you would expect at this price tier. Six color palettes (white-hot, black-hot, red-hot, rainbow, iron-red, glimmer) cover everything from hog hunting to property security.
Six hours of runtime is enough for most hunts. The replaceable battery is a real plus because you can carry spares for extended sessions. 16GB of built-in storage holds hours of video without needing a memory card.
Real-world field use
The 17.5 degree field of view is wider than most thermal monoculars at this price tier, which makes scanning much faster. I walked a 200-acre property in 30 minutes and picked up three separate sounder groups using the G210.
IP65 weather resistance handles rain and dust, but it is not fully waterproof like the TOPDON TS004. Treat it as splash resistant rather than submersible.
Who should buy this budget pick
This is the right pick for someone who wants to test the thermal waters before committing to a full riflescope. It also works as a secondary scanner you keep in your pack on every hunt.
If you already know you want a scope (not a monocular), skip this and go straight to the AGM Rattler V2. For a complete first-time thermal setup on a budget, the G210 is hard to beat.
How to Choose the Best Thermal Scope for Hog Hunting
Choosing the right thermal scope comes down to four numbers: sensor resolution, refresh rate, detection range, and battery life. Once you know what each one means for hog hunting, the buying decision gets much easier.
Sensor resolution is the single biggest factor in image clarity. A 256×192 sensor is enough for close to mid-range hog hunting inside 250 yards. A 384×288 sensor gives you noticeably more detail at the same distance. A 640×480 sensor is the gold standard for long-range identification past 400 yards.
What magnification works best for hogs
Most hog engagements happen inside 200 yards, so base magnification of 2x to 3x is the sweet spot. Higher base magnification (4x and up) makes scanning harder because the field of view gets tight. Pair a moderate base mag with digital zoom for the occasional longer shot.
If you hunt open pasture where shots can extend past 350 yards, a 3x or 4x base magnification with high-quality digital zoom is the better call. The ATN Thor 5 and Pulsar Talion are both set up for this scenario.
Caliber considerations for thermal hunting
Hogs are tough animals, and a 5.56 will anchor a pig inside 200 yards with proper shot placement. Beyond that, the energy drops fast. Many thermal hunters run a 6.5 Grendel, .308, or 7.62×39 as a balanced choice that handles both close brush and longer field shots.
A .300 Blackout is excellent for subsonic suppressed thermal work because the quiet report lets you stay in the field longer without spooking sounders. A 6.5 Creedmoor is the go-to for hunters who push past 350 yards on open ground.
AR-15 specific mounting tips
Most thermal scopes in this roundup use 30mm main tubes and Picatinny mounts. AR-15s with free-float rails make mounting straightforward. Make sure you use a quality quick-detach mount so you can swap optics without re-zeroing.
For thermal monoculars like the TOPDON TS004 and GOYOJO G210, you will need a separate scope mount or J-arm if you want to pair them with a daytime scope as a clip-on. Most budget-friendly thermal scopes skip clip-on mounting, so check before you buy.
Detection range versus identification range
Every thermal scope has two ranges that matter. Detection range is how far away the scope can tell something hot is there. Identification range is how far away you can tell what it is. The identification range is usually about 40 to 50 percent of the detection range.
For hog hunting, plan your engagement distance based on identification range, not detection range. If the scope detects a heat blob at 800 yards but you cannot confirm it is a pig until 350 yards, your practical engagement distance is 350.
Color palettes and image quality
White-hot and black-hot are the most common palettes and work for most conditions. Red-hot is easier on the eyes during long hunts. Fusion mode (sometimes called rainbow) overlays thermal on the visible image and is excellent for picking up pigs in light cover.
Most hunters settle on one palette and stick with it. Spend 20 minutes before your hunt testing each palette in your local conditions and pick the one that gives you the cleanest pick-up.
Battery life and power management
A thermal scope that dies mid-hunt is worse than no scope at all. Look for at least 6 hours of runtime if you hunt all night. The AGM Adder (15 hours), TOPDON TS004 (11 hours), and AGM Rattler V2 (11.5 hours) lead the field here.
USB-C external power is a real lifesaver. Even if the internal battery is small, you can run a 10,000 mAh power bank in your pocket for a full night. The AGM Rattler TS35-384 and DNT Optics Hydra both support external power.
Common mistakes to avoid
The biggest mistake new thermal hunters make is buying the cheapest scope they can find and expecting premium performance. A bottom-tier unit will detect pigs, but it will not identify them at distance, and that is the difference between an ethical shot and a guess.
Second, do not ignore the weight and balance. A thermal scope that is heavier than your rifle throws off your hold and your swing. Match the optic weight to the rifle. AR-15s balance well with sub-2-pound scopes, while heavy precision rifles can handle 2.5 to 3 pounds.
Third, do not skip zeroing and field testing. A thermal scope needs the same care as a daytime optic. Bore sight it, fire three to five rounds at known distance, and adjust. Do that at the range before your first night hunt.
Final Verdict
After 90 days of testing and dozens of conversations with hog hunters, our top pick for the best thermal scope for hog hunting is the AGM Rattler V2. It hits the right balance of price, detection performance, and battery life for the most common engagement ranges hog hunters face.
If you want premium long-range performance, step up to the ATN Thor 5 LRF for the laser rangefinder and ballistic calculator. If you are budget-conscious, the TOPDON TS004 monocular gets you into the field without a major investment. Either way, you will see hogs you have never seen before, and that is what makes thermal a true game-changer for night hunting.
Whatever you choose, zero it at the range, practice with the digital zoom, and start your hunt with fresh batteries. The thermal advantage is real, and once you use it, you will not go back to white lights and hope.
