Best Thermal Clip On Hog Hunting: The ATN TICO 6 640 Keeps Your Day Scope

Hogs move at night, they move in numbers, and they move fast once the first one bolts. The best thermal clip on hog hunting has to keep up with all three without making you rebuild your rifle. The ATN TICO 6 640 does exactly that: it clips in front of the day scope you already shoot, holds your zero, and turns a body-heat signature into a clear target across a dark field. You keep the rifle you know, add thermal in seconds, and you are ready when a sounder files out of the brush at last light. This roundup ranks ATN's 6th-gen TICO 6 clip-ons for the specific demands of chasing pigs after dark.

Why ATN's 6th-gen clip-ons suit hog hunting

Hog hunting punishes gear that is slow or fussy, and the TICO 6 line was built to survive it. Because a clip-on sits in front of your day scope instead of replacing it, you do not re-zero every time you switch from daylight scouting to a night sit — your rifle shoots the same. Pigs run in groups and scatter the instant one spooks, so the 50 Hz refresh matters: it keeps a bolting hog smooth in the frame instead of a smeared blur. Hot Point Tracking tags the warmest body in a milling sounder, which helps when six pigs overlap in the grass. Recoil Activated Video starts recording on the shot, so you can confirm a hit and review the sit later. And when you need to glass a field edge before setting up, the TICO 6 pops off and becomes a handheld thermal monocular. Every one of these is current 6th-gen hardware; older ATN clip-ons are not in this comparison because they lag on sensor, display, and processing.

Best for hogs overall: ATN TICO 6 640x512 1-15x

The ATN TICO 6 640 is the top pick for pigs because it shows you the whole picture across a wide, dark field. The 640x512 sensor carries more detail — more dots in the image, like stepping from standard definition to HD — so when a sounder is rooting at the far edge of a bean field, you can count bodies and read posture before you ever slip off the safety. Detection out to 3500m means the hogs are crisp long before they are in range.

Reading a sounder in the grass

Hogs pile up and overlap, and low-detail thermal turns that into a warm blob. The 640, feeding a Full-HD OLED display, keeps the pigs separated so you can pick the shot you want. Push your day scope to higher power and the image still holds together. That matters most on the big pig at the back of the group, the one you actually came for — with enough resolution you can single it out of the churn instead of guessing.

Built to take the pounding

Hog rigs live hard: mud, dew, dropped packs, and recoil night after night. The 640 is IP67 waterproof, so a river-bottom fog or a spilled sit does not end the hunt, and it runs SharpIR to hold the picture together when the air turns damp. Recoil Activated Video logs every shot to 64 GB of storage, which is handy for settling whether that was a clean hit before you go looking in the dark. When you need to relocate a scattered sounder, pull the clip-on and use it as a handheld scanner to find where they regrouped.

Who it is for, who it is not

It is for the hog hunter working open ground, food plots, and long field edges who wants to identify and count before committing. It is not the lightest option, so if you still-hunt thick creek bottoms where shots are close and quick, the 384 will serve you better and lighter. At 564 g it is the heavier of the two, the fair trade for the bigger lens and sensor.

Best value for hogs: ATN TICO 6 384x288 1-12x

The ATN TICO 6 384 is the hog hunter's value pick, especially where cover is close and shots come fast. The 384x288 sensor gives you a clean, readable picture with detection to 2710m — far more than you will ever need in a creek bottom or a brushy fence line — and it is a bit lighter on the rifle and a bit longer on the battery.

Built for close, brushy pigs

Paired with a 1-12x day scope, the 384 is quick to get on a pig that busts out of cover at fifty yards. You keep Hot Point Tracking, Recoil Activated Video, and the handheld scan mode, so you lose nothing but reach and a little resolution. In tight creek bottoms and brushy fence lines, where a hog might show for only a second or two, the lighter weight helps you swing on it fast, and the shorter engagement distances mean the 640's extra range would simply go unused.

A full night in the swamp

The 384 edges the 640 on runtime, and on the kind of long, still sit that hog hunting rewards, an extra bit of battery is welcome. The 18650 is replaceable, so a spare in a chest pocket keeps you hunting until the last group comes through. Everything else — the weatherproofing, the app, the storage — matches the flagship.

Who it is for, who it is not

It is for hunters who take most of their pigs inside a couple hundred yards and want to spend less to get there. It is not the pick for long, open fields where the 640's extra detail earns its place.

How to choose your hog clip-on

Pick by the ground you hunt hogs on, then match the hardware. Be honest about the distances you actually shoot pigs, not the ones you imagine — most hog kills happen closer than hunters expect, and buying more range than you use just adds weight and cost. Start with terrain, layer in how you hunt, and let those two answers point you to the right sensor. A hunter who sits open bean fields and one who slips creek bottoms in the dark are buying two different tools, even though both are chasing the same animal.

• Open fields — go 640 for the detail to count and separate pigs at distance.
• Thick cover — the 384 is lighter and quicker for close, fast shots.
• Refresh rate — both run 50 Hz, so a scattering sounder stays smooth in the frame.
• Keep your zero — both ship with a Quick Detach mount; clip on before the sit, pull it after, zero holds.
• Battery — replaceable 18650s on both; a spare in your pocket means an all-night sit.
• Confirm the shot — Recoil Activated Video on both records the moment you fire.

Whichever you choose, you are keeping the rifle you already trust. Both live in ATN's thermal clip-on family. For a wider look at the whole line, see our best thermal clip on 2026 roundup.

How we picked these ATN thermal clip-ons for hogs

We judged these clip-ons against the reality of night hog hunting: groups of fast, warm animals in fields and thick bottoms, shot with a rifle you do not want to re-zero. The criteria were sensor resolution (so overlapping pigs stay separate, not a blob), thermal sensitivity for humid Southern nights, detection range, 50 Hz refresh for scattering sounders, weight on a rifle you carry for hours, and battery life that finishes a sit. Only the current 6th-gen TICO 6 line was considered. The honest trade-off is reach versus weight: the 640 identifies and counts at distance but weighs more and runs a little shorter, while the 384 is quicker and lighter for close cover but gives up some range. Neither suits a hunter who only shoots pigs in daylight. This is an in-house comparison of ATN's own clip-ons, not an independent field test, so weigh the specs against the terrain you actually run pigs on.

Frequently Asked Questions

What is the best thermal clip on for hog hunting?

The ATN TICO 6 640x512 is the best pick for most hog hunters. Its high-resolution sensor separates overlapping pigs in a sounder and reaches out across open fields, while it clips in front of your zeroed day scope so nothing about your rifle changes. For close, brushy hunting the TICO 6 384 is the lighter value option.

Do I have to re-zero when I add a clip-on for hogs?

No. The TICO 6 mounts in front of your day scope and never touches its internals, so your zero holds. The included Quick Detach mount lets you clip it on for a night sit and pull it off afterward without losing point of aim.

Can a clip-on separate hogs in a tight sounder?

Yes, if the resolution is high enough. The 640 sensor keeps individual pigs distinct even when they overlap in the grass, so you can pick your shot instead of aiming at a warm blob. The 384 does this well at closer range.

Will it record my hog shots?

Yes. Both TICO 6 clip-ons include Recoil Activated Video, which starts recording when the rifle fires. You can confirm the hit and review the whole sit later on the 64 GB of on-board storage.

Can I scan for pigs before I set up?

Yes. Pop the TICO 6 off the rifle, attach the eyepiece, and it works as a handheld thermal monocular. That lets you glass a field edge or a fence line and locate a sounder before you ever settle in to shoot.

Is thermal better than night vision for hogs?

For finding hogs, thermal has the edge because it reads body heat and cuts straight through grass, brush, and darkness. A hot pig stands out even when it is bedded in cover, which is why a thermal clip-on is the popular choice for pressured, nocturnal hogs.
