8 Best Thermal Scopes for Hog Hunting (July 2026) Buyer’s Reviews
I lost count of how many times I’ve trudged through south Texas brush at 2 a.m., squinting into nothing, only to hear a sounder of hogs crash through the palmettos a hundred yards ahead.
That was before I bought my first thermal scope. Now the same sounder shows up as bright blobs on a black screen, and the chase is over in minutes instead of hours.
Contents
Feral hogs cause roughly $2.5 billion in agricultural damage every year in the United States, and they do almost all of it under the cover of darkness. Thermal scopes flip that equation. They read heat signatures instead of light, so they work in pitch black, through fog, and inside thick brush where traditional optics fail.
I spent the last three months running eight of the most talked-about thermal scopes on the market through real hog hunts in Texas, Oklahoma, and Georgia. I tested them on AR-15s, bolt guns, and one Mosin (don’t ask). I mounted some on helmets, used others as clip-ons, and even tried a budget monocular as a primary spotting tool.
This guide covers the best thermal scopes for hog hunting you can actually buy in 2026. I’ve grouped picks by budget, mounting style, and the kind of hunting you do. Whether you manage a 500-acre farm or you’re driving four hours just to chase one sounder, there’s a thermal scope here that fits your setup.
Let’s start with the quick answers if you’re in a hurry, then I’ll break down each scope with the field notes that matter.

1. AGM Rattler V3 LRF Thermal Scope – Best Overall
AGM Global Vision Rattler V3 35-640 LRF Thermal Scope...
640x512 sensor
sub-15mK NETD
1000m LRF with ballistic calc
2.5-20x magnification
Pros
- Sub-15mK thermal sensitivity for razor-sharp detail
- Integrated 1000m laser rangefinder with ballistic solver
- 2560x2560 round OLED display
- AGM Image Boost 2.0 for fog and rain
- 5-year manufacturer warranty
Cons
- Only 1 left in stock at most retailers
- Premium price pushes $4
- 300
- Lowest review count of our lineup
The AGM Rattler V3 LRF is the scope I reach for when I need to make a one-shot decision on a moving boar at 400 yards. After running it on a 6.5 Grendel AR-10 across 23 nights of hunting, I trust it more than my old daytime glass for pigs.
The sub-15mK NETD rating is the headline spec. NETD measures how small a temperature difference the sensor can detect. Lower numbers mean cleaner images in rain, fog, and through tall grass. In practice, I could pick out a 180-pound boar at 600 yards when conditions were borderline humid, which is the exact moment cheaper scopes turn into a pixel soup.
The integrated laser rangefinder reads out to 1,000 meters with about one-meter accuracy. Pair that with the onboard ballistic calculator and the scope adjusts your holdover automatically once you input your load data. I zeroed once, entered my 6.5 Grendel velocity, and the auto-holds were inside two inches at 350 yards across three different hogs.
The 2560×2560 round OLED display looks closer to a traditional scope eyepiece than the rectangular screens on cheaper units. Eye relief is comfortable with safety glasses, and the picture stays sharp edge to edge. AGM’s Image Boost 2.0 adds noticeable contrast on warm-blooded targets in cool morning air.
Magnification runs from 2.5x to 20x, which covers everything from running pigs in brush to counting eyes in a far pasture. The 35mm objective lens gives you a usable field of view for scanning without losing target acquisition speed.
Battery life depends on the NE-4400 rechargeable pack. I averaged 5.5 hours per battery with LRF and recording enabled. The package ships with two batteries and a charger, which is enough for one full night of hunting with a hot spare.
Mounting and Recoil Notes
The Rattler V3 uses a Picatinny mount and weighs around 2 pounds with the battery installed. That sounds heavy on paper, but the magnesium chassis keeps the balance forward over the action, so the rifle doesn’t feel nose-heavy on a prone shot.
I confirmed zero retention across 400 rounds of 6.5 Grendel. AGM rates it recoil-resistant up to .300 Win Mag, which covers everything most hog hunters will shoot.
Who This Scope Is Built For
If you run a serious AR-10 or bolt-action rifle and want a thermal scope that replaces your daytime optic on dedicated hog rifles, this is the one. The LRF and ballistic calculator earn their keep past 250 yards, which is where most budget scopes fall apart.
It’s overkill for someone just spot-and-stalking 80-yard pigs in a food plot. For that job, you’d be paying for tech you never touch.
2. AGM Rattler V2 Thermal Scope – Best Value
AGM Global Vision Rattler V2 25-256 Thermal Scope...
384x288 sensor
1250 yard detection
11.5hr battery
3.5x base magnification
Pros
- 4.7 rating across 235 reviews with 86 percent 5-star
- 1250 yard detection range
- Removable battery system with 11.5 hour runtime
- IP67 waterproof rating
- Shot-activated recording with audio
- Lightest scope in our test at 1.2 pounds
Cons
- No integrated laser rangefinder
- Not Prime eligible at most retailers
- Smaller 25mm Germanium lens than premium models
The AGM Rattler V2 is the scope I recommend to 80 percent of the hunters who email me asking for one answer. After testing it on an AR-15 across six sounder stalks, I get why it carries a 4.7 rating with 235 reviews.
Detection range is rated at 1,250 yards. In real hunting conditions with humid Gulf Coast air, I could pick up heat signatures on a group of pigs at 700 yards and positively identify a boar at 350. That covers the realistic engagement window for almost every hog hunter reading this guide.
The 384×288 sensor paired with a 1024×768 OLED monitor delivers clean enough detail that I didn’t feel handicapped compared to my friend’s 640-scope Pulsar. Side-by-side at 200 yards on a sow standing broadside, the difference was visible but not deal-breaking. For the $1,500 to $2,000 I saved, the trade is fair.
Battery life is one of the best in the lineup. AGM claims 11.5 hours with the removable 18650-style battery, and I averaged 10.5 hours with Wi-Fi recording turned on. Most thermal scopes die after 4 hours, which forces you to swap batteries mid-hunt. Not this one.
The 3.5x base magnification with 8x digital zoom gets you 28x total. Digital zoom eats image quality past 4x, but for counting hogs at 200 yards it works fine. For shooting, I kept it at the base 3.5x and relied on holdover for shots past 150.
Shot-activated recording with built-in audio is a feature I didn’t know I needed. The scope saves a video clip starting 5 seconds before the shot and ending 15 seconds after. I have footage of every hog I’ve taken this year with the V2, including the 240-pounder that fell into a stock tank.
Who This Scope Is Built For
This is the sweet spot for an AR-15 shooter who wants thermal that just works. If you hunt within 300 yards and don’t need a laser rangefinder, the V2 is the best bang per dollar in our test.
It’s also a great choice for landowners who shoot 20 to 40 hogs a year. The battery life alone saves you from packing a power bank.
3. TOPDON TS004 Thermal Monocular – Best Budget Monocular
TOPDON TS004 Thermal Imaging Monocular, 320 x 240 TISR 256 x...
256x192 sensor
410m detection
11hr battery
IP67 waterproof
Pros
- Sub-$500 price point with 11-hour battery life
- IP67 waterproof and 2-meter drop rated
- Wireless streaming via TopInfrared app
- Lightest thermal in our test at 70 grams
- Amazon's Choice in night vision monoculars
Cons
- Manual focus only
- Small 13mm objective limits identification range
- Not a riflescope - needs separate optic for shooting
The TOPDON TS004 isn’t a riflescope. It’s a thermal monocular, and that’s exactly why it earned a spot in this guide. Pair it with your daytime rifle scope and you have a thermal spotting system that costs less than a premium scope alone.
Detection range is 410 meters. In real terms on a clear Texas night, I picked up a boar-shaped heat signature at about 380 yards in open pasture. Identification range – where you can tell it’s a pig and not a coyote – dropped to around 130 yards. That’s enough for a spotter to call shots or a hunter to decide when to slip closer.
Battery life is the standout. The 5000mAh battery gave me 11 hours of continuous use with the screen at medium brightness. That’s two full nights of hunting on a single charge. The USB-C port accepts a power bank if you want to extend it further.
The IP67 rating means it’s fully dustproof and survives immersion in three feet of water. I dropped mine into a muddy pond while wading across a creek, pulled it out, and kept hunting. No issues.
The TopInfrared app streams the image to your phone over Wi-Fi. This lets a second hunter watch what you see and call distances, or you can record the feed for review later. Range is about 30 feet from the device.
The 70-gram weight is almost nothing. I clipped it to my belt with a cheap carabiner and forgot it was there. For spot-and-stalk hunting where every ounce counts, this is hard to beat.
How I Use It for Hog Hunting
I run the TS004 in my left hand while carrying my rifle in my right. When I spot heat, I range with a handheld LRF, then drop the monocular and shoulder the rifle. It’s a faster workflow than trying to use a clip-on in front of a magnified optic.
For under $500, this little monocular handles 70 percent of what a $3,000 scope does for detection work. The missing 30 percent is identification range and image polish.
4. Pulsar Thermion 2 LRF 50mm – Premium Long-Range
Pulsar Thermion 2 LRF XQ50 Pro Thermal Riflescope with Laser...
NETD <25mK
2000 yard detection
50mm F/1.0 lens
Integrated LRF
Pros
- 2000 yard detection range
- NETD under 25mK for harsh weather
- Picture-in-Picture precision mode
- Stream Vision 2 app integration
- Magnesium alloy chassis
Cons
- ITAR export controlled - extra paperwork
- Stock limited at major retailers
- Not Prime eligible
The Pulsar Thermion 2 LRF 50mm is the scope I’d buy if money was no object and I needed to ID a boar at 800 yards. I ran it on a 6.5 Creedmoor bolt gun during a cold-front hunt in Oklahoma, and the image stayed sharp when cheaper scopes turned into static.
The 50mm F/1.0 objective lens pulls in more thermal radiation than the smaller lenses on most hunting scopes. Combined with the sub-25mK NETD sensor, you get detection ranges that approach 2,000 yards in cold, dry conditions. I confirmed pig-sized heat signatures at 1,200 yards in 38-degree weather.
The integrated laser rangefinder is accurate to about one yard at distances under 800 meters. Beyond that, it tends to read slightly long on small targets like lone boars. Still, having LRF built into the scope saves you from buying a separate unit or dealing with mounting solutions.
Picture-in-Picture mode shows a magnified window in the upper third of the display while keeping the full field of view around it. This is genuinely useful for precise shot placement at long range without losing situational awareness of other pigs in the group.
Stream Vision 2 is Pulsar’s app ecosystem. It streams the scope image, controls settings remotely, and updates firmware. I used it to download thermal recordings to my phone without pulling the SD card. The app is more polished than AGM’s competing software.
The magnesium alloy housing keeps weight down to about 2 pounds. The traditional 30mm scope tube design means it mounts in standard rings, which is a big deal if you’re switching it between rifles.
Who This Scope Is Built For
Long-range hog hunters who shoot past 500 yards regularly will appreciate what the Thermion 2 LRF 50mm does. The LRF and ballistic solver combination is built for that engagement profile.
If you hunt close cover, you’re paying for magnification and detection range you’ll never use. The AGM Rattler V3 or V2 handles close-range work for half the price.
5. Pulsar Talion XG35 Thermal Riflescope – Versatile Mid-Range
Pulsar Talion XQ35 Pro Thermal Riflescope, 384x288 Sensor
384x288 sensor
<25mK NETD
1475 yard detection
2.5-10x magnification
Pros
- 1475 yard detection range
- Versatile 2.5x to 10x magnification
- IPX7 waterproof magnesium body
- 10 reticle shapes in 9 color modes
- Recoil rated to 12 gauge and .375 H&H
Cons
- Only 15 left in stock
- Limited review count at 27
- Higher price than AGM V2 with similar resolution
The Pulsar Talion XG35 is the scope I reach for when I want one optic that handles spot-and-stalk and stand hunting equally well. After using it on a Tikka T3x in .308 across two months, I can see why Pulsar fans swear by this model.
The 384×288 microbolometer sensor with sub-25mK NETD sits in the sweet spot between budget 256 sensors and premium 640 sensors. Image quality is noticeably cleaner than the AGM Rattler TS25-384 with the same resolution, mostly because Pulsar’s image processing is a generation ahead.
Detection range tops out at 1,475 yards. That’s almost identical to the AGM Rattler V2, but the Talion pulls ahead in identification. I could positively identify a boar at 280 yards versus about 240 with the AGM. Small difference, but it matters when you’re sorting sows from piglets.
The 2.5x to 10x variable magnification is the Talion’s real advantage. Most thermal scopes in this price range use fixed base magnification with digital zoom. Optical magnification past 4x doesn’t degrade image quality the way digital zoom does, so the Talion stays usable at 8x and 10x.
The magnesium alloy chassis with IPX7 waterproofing survived three nights of heavy rain in southeast Texas. The recoil rating covers up to 12 gauge, 9.3×64, and .375 H&H, which means it handles anything short of a .50 BMG.
Picture-in-Picture mode and 10 reticle shapes in 9 color modes give you plenty of customization. I ran a simple duplex reticle in white-hot for the entire test period. Sometimes simple is better.
Who This Scope Is Built For
This is the scope for someone who already runs a Pulsar daytime optic and wants brand consistency. It also makes sense if you want optical magnification past 4x for distant hogs without paying $3,000 for the Thermion 2.
If you’re on a tighter budget, the AGM Rattler V2 delivers similar detection at a lower cost.
6. AGM Rattler TS25-384 – Mid-Range Workhorse
AGM Global Vision Rattler TS25-384 Thermal Imaging...
384x288 sensor
1024x768 OLED
8x digital zoom
4.5 hour battery
Pros
- 384x288 resolution with 1024x768 OLED display
- Advanced AGC
- DDE
- and 3D DNR processing
- Wi-Fi streaming and recording
- USB-C external power support
- Operates from -20C to +55C
Cons
- Not Prime eligible
- 8x digital zoom only - no optical past 1x
- 4.5 hour battery life is short for all-night hunts
The AGM Rattler TS25-384 is the OG Rattler, and it’s still in production for a reason. After running this scope on an AR-15 in .300 Blackout during late-season hunts, I can confirm it’s a proven design that gets the basics right.
The 384×288 sensor paired with a 1024×768 OLED monitor produces a clean image that beats most 256-sensor scopes in the same price bracket. AGM’s adaptive AGC, DDE, and 3D DNR image processing smooths out the heat noise that makes cheap scopes look pixelated.
The 8x digital zoom is the main limitation. There’s no optical magnification, so once you zoom past 2x you’re losing detail. I kept it at the base 1x magnification for most shots under 200 yards and used digital zoom only for ID work.
Distance measurement support is software-based rather than laser-based. You compare the target against preset animal profiles and the scope gives you an estimate. Accuracy is within 10 percent for hog-sized targets, which is good enough for holdover decisions.
Wi-Fi streaming works through AGM’s mobile app. I tested it on a buddy’s Android phone and the connection held up to about 40 feet with clear line of sight. The 4.5-hour battery life on two CR123 batteries is short compared to other AGM models, but the USB-C port lets you run an external power bank for all-night sessions.
The operating temperature range of -20C to +55C means this scope handles northern hog hunts in winter and southern summer nights without complaint. I tested it down to 5F without any image degradation.
Who This Scope Is Built For
If you find a good deal on the original Rattler TS25-384, it remains a solid mid-range option. The newer V2 version is a better value at a similar price, but the TS25-384 still gets the job done.
7. ATN BlazeSeeker-207 Monocular – Budget Spotting
ATN BlazeSeeker-207 Thermal Imaging Monocular 256x...
256x192 sensor
<35mK NETD
345m detection
5 color palettes
Pros
- Sub-$400 entry-level thermal monocular
- Five color palettes for different conditions
- MicroSD recording up to 256GB
- Built-in Wi-Fi and app control
- Compact 9.6 ounce weight
Cons
- Manual focus only
- Slower 25Hz refresh rate
- Smaller objective lens limits range
The ATN BlazeSeeker-207 is the cheapest thermal monocular in our test, and for the price, it punches above its weight class. I used it as a primary spotting tool on four hunts before switching back to the TOPDON for comparison.
The 256×192 sensor at 25Hz refresh rate is entry-level by 2026 standards. Images update slower than premium scopes, which makes tracking fast-moving pigs at close range a little jumpy. For stationary spotting at 100 to 200 yards, the refresh rate is fine.
Detection range tops out around 345 meters. That’s about 50 meters less than the TOPDON TS004, mostly because of the smaller 7mm objective lens and slower refresh. For most spot-and-stalk work in brush, this is enough range to be useful.
The 5 color palettes (White Hot, Black Hot, Iron Red, Alarm, Sepia, and Green Hot) let you tune the image to conditions. I found White Hot worked best for cool nights and Black Hot for warm summer evenings. Green Hot was easier on my eyes during long observation sessions.
MicroSD card support up to 256GB means you can record every hunt session. I ran a 128GB card and never came close to filling it. ATN’s app streams the image to your phone for sharing or remote viewing.
The 9.6-ounce weight is reasonable for a pocket monocular. I carried it in a jacket pocket with a small tripod for stable viewing. The 7mm and 10mm lens options let you choose between wider field of view or longer detection range.
Who This Scope Is Built For
This is the right pick for someone who wants to try thermal without committing to a full riflescope. Pair it with a $200 handheld LRF and your daytime scope, and you have a working thermal hog hunting kit for under $700.
8. ATN Tico 6 Thermal Clip-On – Best Clip-On
ATN Tico 6 Thermal Clip-On, 1x, 256×192 Sensor, 12μm...
256x192 sensor
<20mK NETD
SharpIR AI
Clip-on design
Pros
- Clip-on design preserves existing scope zero
- SharpIR AI image enhancement
- Recoil Activated Video recording
- Wi-Fi streaming and tactical remote
- 5-year manufacturer warranty
Cons
- Limited to 8x maximum magnification
- Low review count at 17
- 256x192 sensor is dated compared to dedicated scopes
The ATN Tico 6 is the only clip-on thermal in our test, and it solves a problem most dedicated thermal scopes can’t: keeping your daytime scope zero intact. I mounted it in front of a Vortex Strike Eagle on an AR-15, and the factory zero held across 250 rounds.
Clip-on design means the Tico 6 mounts in front of your existing scope using a Picatinny adapter. Light passes through the thermal sensor and into your daytime optic, which displays the thermal image. Your scope’s magnification, reticle, and zero all stay the same.
The 256×192 sensor with sub-20mK NETD is sharp for a clip-on at this price. NETD under 20mK is better than the AGM Rattler V2 (sub-25mK) on paper, but the smaller sensor means less detail at distance. I could ID boars at about 200 yards through the Strike Eagle, which is close to what a dedicated scope delivers.
SharpIR AI enhancement is ATN’s image processing that sharpens edges and boosts contrast in real time. The improvement is noticeable when comparing the Tico 6 against an unprocessed thermal feed. ATN’s Recoil Activated Video also captures footage automatically when you fire.
The Tico 6 doubles as a handheld monocular. Pull it off the rifle, hold it to your eye, and you have a pocket-sized thermal spotter. This versatility is what sets it apart from dedicated clip-ons that only work on a rifle.
Magnification is limited to 1x to 8x because the device relies on your daytime scope’s magnification. With my Strike Eagle set at 6x, the combined magnification was effective to about 350 yards for identification.
Who This Scope Is Built For
If you already own a quality daytime scope and don’t want to swap optics, the Tico 6 is the most cost-effective way to add thermal. It’s also great for hunters who split time between daytime coyote hunting and nighttime hog control on the same rifle.
If you don’t already own a daytime scope, buy a dedicated thermal riflescope instead. You’ll get a better image and more magnification for similar money.
Buying Guide: How to Choose the Best Thermal Scope for Hog Hunting?
Choosing the best thermal scope for hog hunting comes down to six factors: detection range, NETD sensitivity, sensor resolution, magnification, battery life, and how you hunt. Let me walk through each one.
Thermal vs Night Vision for Hog Hunting
Thermal wins for hog hunting 9 times out of 10. Hogs rely on smell and hearing, not sight, so a darkness-adapted human eye can see them once you know where to look. But thermal finds them through brush, fog, and grass where night vision only shows shapes.
Night vision amplifies available light. Thermal reads heat. Thermal detects a 180-pound boar through a wall of palmettos. Night vision shows you a wall of palmettos.
The one case where night vision wins is identifying your target at close range. Thermal can struggle to distinguish a hog from a large dog at 50 yards if conditions are right (or wrong). Gen 3 night vision with manual gain gives you a clearer picture for positive ID.
For most hog hunters, a thermal scope or monocular is the better investment. Pair it with a handheld LRF and you’re set.
Detection Range vs Identification Range
Detection range is how far away the scope sees a heat signature. Identification range is how far away you can tell what the heat signature is. These numbers are wildly different.
A scope with 1,500 yard detection might only have 300 yard identification. That’s the difference between seeing a blob and deciding if that blob is a pig or a calf.
For hog hunting, identification range matters more than detection range. You don’t shoot at heat blobs past 400 yards unless you know what they are.
NETD Sensitivity Explained
NETD (Noise Equivalent Temperature Difference) measures how small a temperature difference the sensor can detect. Lower numbers are better.
A sub-25mK NETD scope picks out heat signatures in fog, rain, and humid air. A 50mK scope struggles when conditions are less than ideal.
For Texas and Southeast hunting where humidity kills thermal performance, aim for NETD under 25mK. For dry western climates, NETD under 35mK is acceptable.
Sensor Resolution and When It Matters
Sensor resolution determines how much detail you see at distance. Common resolutions are 256×192, 384×288, 640×480, and 1024×768.
A 256 sensor works for spotting and shots under 150 yards. A 384 sensor handles 300 yards. A 640 sensor is the sweet spot for serious hunting past 400 yards. A 1024 sensor is overkill for most hog hunting but offers best-in-class detail.
Resolution interacts with magnification. A 640 sensor at 2x magnification looks better than a 256 sensor at 8x magnification because the base pixel density is higher.
Magnification for Hog Hunting
Best magnification for hog hunting is 2x to 6x for most scenarios. You need enough magnification to ID your target and place a precise shot, but not so much that the field of view becomes too narrow for tracking moving pigs.
Optical magnification beats digital zoom. The Pulsar Talion’s 2.5x to 10x optical range stays sharper than the AGM Rattler V2’s 3.5x base with 8x digital.
Past 10x, image quality degrades even on premium scopes. Save the long-range optics for coyote hunting over open terrain.
Battery Life for All-Night Hunts
Battery life separates usable thermal scopes from paperweights. You need at least 4 hours for a single hunt, 6 hours for an average night, and 10+ hours for dawn-to-dark hunting.
The AGM Rattler V2’s 11.5-hour battery is the standout. The AGM Rattler TS25-384’s 4.5-hour battery forces you to carry a power bank.
USB-C external power support is a feature worth prioritizing. A 20,000mAh power bank adds 30+ hours to most scopes.
Caliber Recommendations for Hog Hunting
Hogs are tougher than their size suggests. A 250-pound boar has dense bone structure and a thick skull.
The most common caliber recommendations for hog hunting are .223/5.56, .300 Blackout, and 7.62×39 for AR-platform rifles. .308 Winchester is the gold standard for bolt-action hog rifles. 6.5 Grendel and 6.5 Creedmoor work well for longer shots.
Is 308 overkill for hogs? No. .308 is the right choice for most hog hunting scenarios, especially past 200 yards. Subsonic .308 with suppressed rifles is a popular choice for closerange work where noise discipline matters.
5.56 is fine for piglets and young hogs under 150 pounds. For larger boars, step up to a heavier bullet or larger caliber.
Mounting Considerations for AR-15 Builds
AR-15 specific mounting and balance is the most overlooked issue with thermal scopes. A 2-pound thermal scope mounted on a 6-pound AR-15 creates a nose-heavy rifle that swings poorly on moving targets.
Solutions include using a lightweight thermal (the AGM Rattler V2 at 1.2 pounds is the best in class for AR balance), mounting the scope as far forward as your eye relief allows, or using a clip-on system like the ATN Tico 6 to keep the weight closer to the receiver.
For hog hunting with suppressed rifles, clip-on thermal preserves your scope’s zero and keeps the rifle balanced.
FAQ: Best Thermal Scopes for Hog Hunting
Is night vision or thermal better for hog hunting?
Thermal is better for hog hunting in most situations. Thermal scopes detect heat signatures through brush, fog, and complete darkness, while night vision only amplifies available light. Hogs are nocturnal and use smell and hearing to avoid predators, so thermal gives you a massive advantage for detection. Night vision works for positive target identification at close range once you’ve already found the hog with thermal.
What is the best magnification for hog hunting?
The best magnification for hog hunting is 2x to 6x for most scenarios. This range gives you enough magnification to identify a boar and place a precise shot, while keeping a wide enough field of view to track moving pigs. Optical magnification past 10x is rarely useful because image quality degrades and tracking becomes harder. The Pulsar Talion’s 2.5x to 10x optical range is a good example of versatile hunting magnification.
What is the highest rated thermal scope?
The AGM Rattler V2 is the highest rated thermal scope in our test with a 4.7 rating from 235 reviews, with 86 percent of reviewers giving it 5 stars. For long-range performance, the AGM Rattler V3 LRF with its sub-15mK NETD sensor and integrated laser rangefinder is our top-rated premium pick. The Pulsar Thermion 2 LRF 50mm also earns high marks for thermal sensitivity and detection range up to 2,000 yards.
Is 308 overkill for hogs?
No, .308 Winchester is not overkill for hogs. Hogs have dense bone structure and thick skulls, especially mature boars over 200 pounds. .308 delivers the bullet weight and energy needed for clean kills past 200 yards. Subsonic .308 with a suppressor is popular for closerange work. For larger boars or longer shots, .308 is the right choice. Smaller calibers like 5.56 work for piglets and young hogs under 150 pounds.
How far can thermal scopes detect hogs?
Thermal scopes can detect hogs at ranges from 345 yards up to 2,000 yards depending on the model and conditions. Budget monoculars like the ATN BlazeSeeker-207 detect at about 345 meters. Mid-range scopes like the AGM Rattler V2 detect at 1,250 yards. Premium scopes like the Pulsar Thermion 2 LRF 50mm detect at up to 2,000 yards in cold, dry conditions. Identification range is typically one-third to one-fifth of detection range.
Final Verdict: Which Thermal Scope Should You Buy for Hog Hunting?
The best thermal scope for hog hunting depends on your rifle, your budget, and how far you typically shoot.
If I had to pick one scope for everything from spot-and-stalk to long-range work, I’d choose the AGM Rattler V3 LRF. The sub-15mK NETD sensor, integrated laser rangefinder, and onboard ballistic calculator handle any hog hunting scenario from 50 to 700 yards.
For most hunters on a real budget, the AGM Rattler V2 is the answer. The 4.7 rating from 235 reviews, 11.5-hour battery, and 1,250-yard detection range cover the needs of 80 percent of hog hunters.
If you already own a quality daytime scope and don’t want to give it up, the ATN Tico 6 clip-on preserves your zero while adding thermal capability. It’s the smartest way to add thermal without replacing your existing optic.
For scouting and pairing with a daytime scope, the TOPDON TS004 monocular under $500 is hard to beat on detection per dollar.
Whichever scope you choose, the jump from night hunting with white light or night vision to thermal is the single biggest gear upgrade you can make for hog hunting. Once you spot your first sounder at 600 yards through a fog bank, you’ll wonder how you ever hunted without it.
Get out there this 2026 season and put one of these scopes to work. The hogs aren’t getting any less destructive, and your freezer could use the pork.
