How to Hunt Hogs with a Thermal Scope at Night: ATN ThOR...

Hog hunting at night is one of the most effective ways to manage feral pig populations, and thermal imaging has completely changed the game. If you're running a quality hog hunting thermal scope, you're not just hunting in the dark — you're hunting with a decisive advantage. This field guide focuses specifically on the ATN ThOR 6 325, walks you through setup, zeroing, field tactics, and explains why it earns the title of best thermal scope for hog hunting in 2026.

Why Thermal Scopes Are Essential for Night Hog Hunting

Feral hogs are nocturnal by nature. They're smart, cautious, and increasingly pressured by daytime hunting. The moment you introduce thermal imaging into your setup, you neutralize their biggest survival advantage: darkness.

Traditional night vision relies on ambient light or IR illuminators. Thermal imaging detects heat signatures directly, which means dense brush, fog, and zero-light conditions become irrelevant. A sounder of hogs moving through a creek bottom at 2 AM glows as clearly as they would at noon, sometimes more so because the surrounding environment is cold by comparison.

For landowners managing crop damage, ranchers protecting livestock, or hunters controlling invasive populations, a purpose-built hog hunting thermal scope isn't optional — it's the most productive tool in the kit.

ATN ThOR 6 325 Review 2026: Why This Scope Leads the Pack

The ATN ThOR 6 325 review 2026 story starts with ATN's 6th Generation thermal engine. This isn't an incremental update — it's a ground-up redesign built around a 384×288 resolution, 12μm pixel pitch, VOx uncooled focal plane array sensor with a thermal sensitivity rating of ≤15mK NETD. That NETD number matters enormously in the field.

NETD, or Noise Equivalent Temperature Difference, measures how small a temperature difference the sensor can detect. At ≤15mK, the ThOR 6 325 can pick up heat signatures that cheaper sensors simply miss — a hog lying still in tall grass, a pig partially obscured behind a tree, a group bedded in thick brush that looks like a solid mass to a lesser scope.

Paired with ATN's proprietary SharpIR© AI-enhanced imaging, every pixel is processed in real time to sharpen edges, boost contrast, and improve target separation. You're not just seeing a heat blob — you're seeing defined shape, body posture, and movement that tells you exactly what you're looking at before you squeeze the trigger.

ATN ThOR 6 325 Specs: What the Numbers Mean in the Field

Here's a detailed breakdown of the ATN ThOR 6 325 specs and what each one means when you're actually running hogs at night:

• Sensor Resolution: 384×288 — delivers crisp, detailed imaging at mid-range and provides enough pixel density to confidently identify targets before engaging
• Thermal Sensitivity (NETD): ≤15mK — detects the faintest heat differences, essential when hogs are partially obscured or bedded in cover
• Lens System: 25mm Germanium, F/1.0 — fast aperture captures maximum thermal energy for brighter, cleaner imagery
• Magnification: 2.5–20× with step and smooth zoom — gives you wide scanning capability and tight engagement zoom in one package
• Field of View: 10.53° × 7.91° — wide enough to spot movement, scan fields, and track running hogs effectively
• Detection Range: 2,300 meters — more than enough for any realistic hog hunting scenario
• Display: 0.49-inch OLED, 1920×1080 resolution — premium image quality that reduces eye fatigue during long sessions
• Battery Life: ~9 hours with dual 18650 rechargeable batteries — covers all-night hunts on a single charge set
• Internal Storage: 64GB — records full hunts without managing SD cards
• Weight: 790g / 1.74 lbs — lightweight enough for extended carry without fatiguing your shooting platform
• IP Rating: IP67 — fully weatherproof, handles rain, dew, and the conditions you'll find on any serious hog hunt
• Operating Temperature: -30°C to +55°C — performs equally in cold northern winters and hot southern summers
• Recoil Rating: 6,000 joules / 1,000g acceleration over 0.4ms — rated for the hardest-hitting rifle platforms

The 325 designation in the ThOR 6 lineup refers to the 384×288 sensor paired with the 25mm lens. For most hog hunters, this configuration hits the ideal balance between wide field of view, strong detection range, manageable size, and competitive price point relative to the higher-resolution 640-series models.

Thermal Scope Setup Guide: Getting the ThOR 6 325 Hunt-Ready

A solid thermal scope setup guide covers everything from mounting to color palette selection. Do this right before you get to the field, not in the dark at your shooting lane.

Step 1: Mount Your Scope

The ThOR 6 325 requires 30mm rings, which are not included. Use quality, repeatable rings — Warne, Vortex, or Leupold rings on a solid base are all appropriate choices. The scope's magnesium alloy housing is tough, but poor mounting will introduce zero shift and defeats the purpose of all that internal precision. Torque your ring screws evenly to the manufacturer's specification — don't crank one side and forget the other.

Position the scope for comfortable eye relief. The ThOR 6 325 provides 50mm of eye relief, which gives you enough clearance to run it safely on hard-recoiling AR platforms and bolt guns alike.

Step 2: Adjust the Diopter

Before you ever fire a shot, dial in the diopter to match your eye. The ThOR 6 325 offers a -5 to +5 diopter range. Point the scope at a neutral background, look through it, and adjust until the reticle is sharp. Don't adjust for the image — adjust until the crosshair itself is crisp. This is a step many hunters skip, and it costs them clarity on every target they ever look at.

Step 3: Select Your Color Palette

The ThOR 6 325 offers six palettes: White Hot, Black Hot, Iron Red, Alarm, Green Hot, and Sepia. For hog hunting in most conditions, White Hot or Black Hot are the two most used options. White Hot renders warm objects as bright white, which makes hogs stand out vividly against a dark background. Black Hot inverts this, which some hunters prefer when working near heat sources like equipment or structures that can wash out a White Hot image. Experiment with both and know which you'll reach for when a group of hogs steps out at 150 yards.

Step 4: Configure Recoil Activated Video (RAV)

Before your first hunt, enable RAV in the menu. This feature automatically records 10 seconds before and after the shot, capturing the kill without any button pressing. It's not just a cool feature — it's a recovery tool. When you watch playback after a shot, you can confirm the hit, observe which direction the animal broke, and improve your recovery efficiency significantly.

Step 5: Enable Hot Point Tracking

Hot Point Tracking automatically highlights the hottest object in your field of view. During a scan, this instantly draws your attention to living animals rather than warm rocks, engine exhaust, or other ambient heat sources. Enable this feature for hunting, and your target acquisition time drops noticeably.

Step 6: Connect the ATN Connect 6 App

Download the ATN Connect 6 app on iOS or Android before your hunt. Connect via the built-in Wi-Fi hotspot. This gives you or a hunting partner a live view of everything you're seeing through the scope, streamed to a smartphone or tablet. It's invaluable for spotting and calling, allowing a spotter to watch the field on their phone while you stay eyes-on through the scope. It's also an excellent tool for coaching new hunters through the process without anyone having to switch positions mid-hunt.

How to Zero a Thermal Scope: ThOR 6 325 Step-by-Step

Knowing how to zero thermal scope correctly is the single most important technical step in your setup. The ThOR 6 325 makes this process significantly easier than traditional scopes through its Zeroing Freeze feature.

What You Need

• A solid shooting rest or bench
• A thermal target — ATN includes a heated zeroing target in the box specifically for this purpose
• A known distance — 100 yards is standard for most hog hunting applications
• Your zeroing ammunition — use the same load you'll hunt with

The Zeroing Process

Set up the heated zeroing target at your chosen distance. The target provides a clear thermal signature that the scope can use as a precise aiming reference. Fire one round from a solid rest. The moment of impact will be visible on the thermal image.

Immediately activate Zeroing Freeze — this pauses the image at the moment of impact so you can see exactly where the round hit without losing the reference point. Navigate to the zeroing menu and adjust your reticle to match the point of impact. The system lets you move the reticle to your point of impact rather than requiring you to move your hold point, which eliminates guesswork.

Confirm with a follow-up shot. If the scope is properly zeroed, that second round should hit precisely where the reticle sits. Three-shot groups give you the best confidence before hunting.

Using Picture-in-Picture for Precision Zeroing

Activate PIP mode during the zeroing process. The main image shows your wide field of view, while the PIP window zooms in on the target. This lets you see fine point-of-impact detail at the highest zoom level without giving up your overall sight picture — precision that traditional scopes simply cannot offer.

Saving Multiple Weapon Profiles

The ThOR 6 325 stores up to five custom weapon profiles. If you're running this scope on multiple rifles — say a .308 bolt gun for precision work and an AR-15 in 5.56 or .300 Blackout for close-range hog runs — zero each separately and save as distinct profiles. Swapping between them takes seconds and requires no re-zeroing, which is a massive practical advantage when you're changing setups between hunts.

Field Tactics: Hunting Hogs at Night with the ThOR 6 325

Equipment is only half of the equation. Successful night hog hunting with a hog hunting thermal scope comes down to reading the field, understanding pig behavior, and executing a well-planned approach.

Scout During the Day, Hunt at Night

Thermal won't replace scouting. Before your night hunt, identify active feeding areas, water sources, wallow locations, and the trails hogs use to move between them. Trail cameras help confirm timing and direction of travel. The ThOR 6 325's 2,300-meter detection range means you can set up farther back than you think necessary, reducing scent pressure on the approach routes hogs use.

Wind is Still King

Thermal eliminates the visibility problem. It does nothing for your scent cone. Hogs have exceptional noses, and a single whiff of human scent will send an entire sounder ghosting into the dark before you get a shot. Always position downwind of expected approach routes. Use the wind to your advantage exactly as you would during any hunting situation.

Scanning Technique

Start your scans at 2.5× — the ThOR 6 325's lowest magnification setting — to cover maximum ground. Systematic, slow sweeps from edge to edge of your field of view. With Hot Point Tracking enabled, any warm-blooded animal in that field will immediately draw the indicator. Once you locate animals, step up the magnification to confirm the target, count the group, and identify the largest animals before engaging.

The wide 10.53° × 7.91° field of view at base magnification is genuinely useful here. You're not scanning through a soda straw — you're covering real ground efficiently.

Shot Selection and Placement

Hogs are notoriously tough animals. A well-placed shot with a .308, .30-06, 6.5 Creedmoor, or larger caliber into the boiler room drops them efficiently. Use PIP mode to zoom into your target's vitals while keeping the wider view active. The OLED display's 1920×1080 resolution gives you the detail to see shoulder definition, head angle, and body position clearly enough to choose your exact aiming point — a capability that makes ethical, clean kills significantly more consistent.

Running Groups

Feral hogs often move in sounders ranging from a handful of animals to groups of 30 or more. After your first shot, the group will typically break and run. With the ThOR 6 325's smooth zoom and Hot Point Tracking, you can immediately acquire running targets for follow-up shots. The 2.5–20× magnification range gives you the versatility to engage targets from close-breaking hogs to animals pushing 200 yards in a single uninterrupted sequence. This is where having a reliable zero and a well-set profile pays real dividends.

Using the Live Feed for Coordinated Hunts

When hunting with a partner or guide, the ATN Connect 6 live Wi-Fi feed transforms the hunt into a coordinated operation. Your spotter watches the feed on a phone while you stay on the rifle. The spotter can call out additional animals, alert you to movement on the edges of your field of view, and help you prioritize targets in a large group — all without any verbal communication that would spook the hogs.

Recording Your Hunt: RAV, Internal Gallery, and 64GB Storage

The ThOR 6 325 includes 64GB of internal storage and a built-in microphone. Recoil Activated Video ensures that every trigger pull captures footage without any action from you. The 10 seconds of pre-shot footage and 10 seconds of post-shot footage create a complete picture of each engagement — the approach, the shot, and the immediate aftermath.

Access everything through the internal gallery directly on the scope, or transfer via USB-C when you're back at camp. There are no SD cards to lose, no adapters to forget, and no complicated file management. Footage is saved directly to the device and stays there until you choose to move it.

For hunters who document their hog control work for landowners or state agricultural programs, this built-in documentation capability has real practical value beyond just capturing great footage.

Battery Management on Long Hunts

The ThOR 6 325 runs on two 18650 rechargeable batteries — one internal and one replaceable external. Combined runtime is approximately 9 hours, which covers the majority of all-night hunts comfortably. The replaceable design means you can carry a second set of charged cells and swap in seconds without any tools, extending your hunt indefinitely.

The scope also supports external power via USB Type-C at 5VDC/2A, which means you can run it from a small power bank in a saddle bag or blind pouch if you're doing extended overnight setups from a fixed position. For landowners running feeders who spend multiple nights out, this is a legitimate option worth knowing about.

Use Standby Mode between active hunting periods — the ThOR 6 325 wakes instantly from standby in under 7 seconds, so you're never caught flat-footed when hogs appear unexpectedly.

The ATN ThOR 6 325 vs. Higher-Resolution ThOR 6 Models

ATN offers the ThOR 6 in 384×288 and 640×512 sensor configurations. The 640-series models provide higher pixel density, longer detection ranges, and even more fine detail at distance. They're also heavier and more expensive. For hog hunting — where most engagements happen inside 300 yards and speed of target acquisition matters more than extreme long-range precision — the 325's 384×288 sensor and 25mm lens configuration is an excellent match to the task.

The ThOR 6 325 weighs just 1.74 lbs, making it the lightest model in the ThOR 6 lineup. That matters when you're mounting it on a rifle you'll be carrying across fields, through creek bottoms, and over fences for hours at a stretch. The 640-series models step up to 1.83 lbs and above — not dramatically heavier, but noticeable over a long night on foot.

The 2,300-meter detection range of the 325 comfortably exceeds any realistic hog shooting distance, leaving substantial margin for pure surveillance, scanning, and locating work before you ever consider a shot.

The SharpIR© Advantage: AI-Enhanced Imaging in the Field

One of the most practically significant features of the ThOR 6 325 is SharpIR© AI-enhanced imaging. This isn't marketing language — it's a real-time processing system that works on every single frame the sensor captures.

In practice, this means that when you're scanning dense brush where hogs like to bed, the edges of those heat signatures are processed to be sharper and more distinct than the raw sensor output would produce. You can differentiate between a hog in cover and a warm rock. You can tell when a heat blob is multiple animals layered together versus a single large pig. You can pick out movement in tall grass because the contrast enhancement makes moving heat stand out against still surroundings.

This translates directly to faster, more confident target identification — which is exactly what you need when a sounder steps into your field and you have 30 seconds to decide who to shoot first.

Common Setup Mistakes to Avoid

Even with the best thermal scope setup guide, hunters make avoidable errors. Here are the most common ones when setting up the ThOR 6 325:

• Skipping the diopter adjustment: Every eye is different. Don't assume the factory setting is right for you. Dial it in every time the scope changes hands.
• Zeroing without a thermal target: A cardboard target at 100 yards won't produce a reliable thermal reference point. Use ATN's included heated zeroing target for clean, repeatable results.
• Not testing RAV before the hunt: Enable and confirm RAV is recording correctly at the range, not in the field after a missed capture.
• Running maximum magnification to scan: Start at 2.5× for area coverage. High magnification narrows your field of view dramatically and slows down target location significantly.
• Ignoring NUC: Non-Uniformity Correction calibrates the sensor periodically. The ThOR 6 325 offers Auto, Semi-Auto, and Manual NUC. In the field, Auto NUC keeps your image clean without intervention — enable it and let it work.
• Forgetting spare batteries: Nine hours is plenty for most hunts, but carry a charged spare set regardless. Cold weather reduces battery performance, and you don't want to lose your scope at 3 AM when the hogs finally move.

ATN ThOR 6 325 in the Broader Context of 2026 Thermal Optics

The ATN ThOR 6 325 review 2026 conversation has to acknowledge how competitive the thermal optics market has become. There are Chinese-manufactured options at lower price points and European alternatives with strong sensor specs. What ATN's ThOR 6 325 offers that distinguishes it in this landscape is the software ecosystem.

The combination of SharpIR© AI processing, RAV, Hot Point Tracking, Zeroing Freeze, PIP mode, built-in Wi-Fi with a full-featured mobile app, multiple weapon profiles, and 64GB internal storage represents a level of integrated functionality that few competitors match at any price point. You're not buying a sensor bolted into a housing. You're buying a system built specifically for the way hunters actually work in the field.

The 6,000-joule, 1,000g recoil rating means you can run this scope on your hardest-recoiling hunting rifles without concern for zero shift or housing damage. The IP67 waterproofing rating handles genuine submersion, not just splashes. The magnesium alloy body survives the abuse that a real hunting season delivers — drops, scrapes, extreme temperatures, and the general punishment of field use across multiple years.

Final Verdict: Is the ATN ThOR 6 325 the Best Thermal Scope for Hog Hunting in 2026?

For hunters whose primary mission is night hog control at realistic field distances — inside 300 yards the overwhelming majority of the time — the ATN ThOR 6 325 earns its position as the best thermal scope for hog hunting in 2026 based on a combination of sensor performance, software capability, build quality, practical weight, and complete field-ready feature set.

The ≤15mK NETD sensor with SharpIR© AI processing produces imagery that directly improves target identification in the brushy, cluttered environments where hogs live.
