Forget the sticker for a second and look at the features that actually kill hogs after dark. For a budget thermal clip on hog hunting decision, a handful of capabilities separate a clip-on that works from one that frustrates — and judged on those, the ATN TICO 6 640x512 leads ATN's current 6th-generation thermal clip-ons. This roundup ranks by the features that decide the night, not by ground or by price.
The features that actually matter on a clip-on
- Zero retention — it mounts ahead of your day scope and must not move your point of impact. All three TICO 6 models use an included Quick Detach mount built to hold zero.
- Detection range — how early you catch a hog's heat, from 1500 m up to 3500 m across the line.
- Sensor resolution — how cleanly a hog reads at distance, from 256x192 to a full 640x512.
- Dual use — a removable eyepiece turns any TICO 6 into a handheld scanning monocular.
- Recoil Activated Video — records the shot automatically, shared across the whole line.
Best resolution and reach: TICO 6 640x512
On the feature that matters most for confident hog shots — a clean picture at distance — the TICO 6 640x512 is the leader. Its 640x512 sensor shows a hog as a defined animal, not a warm smear, and detection to 3500 m through a 50 mm germanium lens gives you the earliest read on a sounder working across a field.
It sits in the flagship tier, but the payoff is that every other feature is uncompromised: it holds zero on the included mount, records on recoil, tracks the hottest point in frame, and pulls off to scan handheld. If you want the most capable clip-on and can meet the higher tier, this is it.
It is a touch heavier at 1.24 lbs, the honest cost of the bigger lens and sensor — a fair trade for the reach.

Best all-round balance: TICO 6 384x288
The TICO 6 384x288 is the feature sweet spot for hunters who do not need the absolute longest reach. It matches the flagship on NETD, zero retention, RAV and dual use, and gives up only some resolution and range for a lighter, mid-tier package. For most hog nights, no single feature holds it back.
Best light and value: TICO 6 256x192
The TICO 6 256x192 is the value-tier entry and the lightest at 1.12 lbs. It keeps the features that make a clip-on worth owning — zero retention, dual clip-on/monocular use, recoil-activated recording — while trimming resolution and range to hit the entry price. For closer-range hog work where you do not need to reach out, it delivers the essentials.
Matching features to your hunt
- Want the cleanest long-range picture — the 640x512's resolution and reach lead the line.
- Want a balanced clip-on with no glaring weakness — the 384x288 is the all-round pick.
- Want the lightest, lowest-tier entry — the 256x192 keeps the core features and trims the rest.
- Want it all regardless — every model retains zero, records on recoil and converts to a monocular; those never change.
Zero retention: the feature you cannot compromise
Of all the features on this list, zero retention is the one that decides whether a clip-on is usable at all. A clip-on sits ahead of your day scope, in the light path, so if it shifts your point of impact even slightly the whole setup is worthless for a clean shot. Every TICO 6 addresses this the same way: an included Quick Detach mount that indexes to the same spot on the rail every time, so the thermal image passes through your optic without moving where the rifle shoots.
In practice that means you sight in your day scope once, in daylight, and trust it after dark. Pull the clip-on off at first light and your zero is unchanged; clip it back on the next night and it is still true. For a hog hunter switching between day and night, that repeatability is the feature that makes the whole clip-on concept work — and it is why we treat it as non-negotiable rather than a bonus.
Dual use: two tools in one budget
The second feature that stretches a budget is the removable eyepiece shared across the TICO 6 line. With it off, the clip-on mounts to the rifle and works through your day scope. With it on, the same unit becomes a handheld thermal monocular you can scan with by hand. For a hog hunter that means one purchase does the job of a scanner and a shooting optic — you glass a field to locate a sounder, then clip the very same device onto the rifle to take the shot.
That flexibility is a real feature, not a gimmick: it saves you buying a separate handheld scanner, which is a meaningful part of what makes a clip-on the budget-smart route to thermal for hogs.
Getting the most out of the feature set
- Set your palette to the ground — White Hot is the default, but Black Hot or a colour palette can lift a hog off certain backgrounds; try each and keep the clearest.
- Let Hot Point Tracking do the work — it flags the warmest object in frame, which speeds up picking the lead animal in a moving sounder.
- Turn on Recoil Activated Video — it captures your shots automatically for confirming hits and reviewing later in the ATN Connect 6 app.
- Keep a spare 18650 — a swap takes seconds and turns a drained cell into a non-event on a long night.
- Check co-witness once — confirm the clip-on and day scope line up so the image stays centred through the optic.
What it looks like on a real night
Hogs slip into a field at the far tree line. Through the 640x512's crisp sensor they resolve as clear, countable bodies at a distance where a lower-resolution optic would show blobs; Hot Point Tracking marks the lead pig, Recoil Activated Video rolls on the shot, and your day-scope zero never budged. That is the feature stack working together — the reason we rank by capability, not by price.
The features that flatter a spec sheet but matter less
It is worth being honest that not every listed feature changes a hog night equally. Built-in Wi-Fi and the ATN Connect 6 app are genuinely useful for pulling footage and tweaking settings, but they do not help you find or shoot a hog — they are conveniences, not deciders. The Full-HD OLED display is a real quality-of-life upgrade over the entry model's smaller screen, sharpening what you see, yet it cannot add detail the sensor never captured.
We call this out because a budget buyer should weight the deciding features — zero retention, detection range and sensor resolution — above the nice-to-haves. A clip-on that nails the first three and skips a fancy app will out-hunt one that dazzles on the spec sheet but comes up short where it counts. That is exactly why our ranking leans on capability that changes the shot, not on the longest feature list. When you read any clip-on's spec sheet, separate the features that put a hog on the ground from the ones that merely look good in a bullet list, and spend your money on the former.
How we picked these ATN thermal clip-ons
This is an in-house comparison of ATN's own current 6th-generation TICO 6 line, not an independent review, so weigh each feature against your own hunting. We ranked by capability because a clip-on lives or dies on a few features: zero retention, detection range, sensor resolution, dual clip-on/monocular use and recoil-activated recording — all measured against real hog work.
We stick to value tiers rather than hard prices, and only the current line. The honest limit: a clip-on has no reticle of its own — it borrows your day scope's — so its magnification depends on the optic behind it. Who it is not for: if you want a fully standalone thermal sight with its own reticle and zoom, a dedicated thermal weapon sight fits better than any clip-on.
Frequently Asked Questions
What clip-on feature matters most for hog hunting?
Zero retention comes first — the clip-on must not shift your point of impact. After that, detection range and sensor resolution decide how early and how clearly you see hogs. The TICO 6 line is built around all three.
Why does the 640x512 lead this list?
It leads on the features that decide confident shots: the highest resolution for a clean picture, the longest 3500 m detection, and no compromise on zero retention, recoil recording or dual monocular use. It is the most capable of the three.
Is the 384x288 missing any important feature?
No — it matches the flagship on NETD, zero retention, recoil-activated video and dual use. It only gives up some resolution and range, which is why it is the balanced all-round pick at a lower tier.
Does every TICO 6 convert to a handheld scanner?
Yes. Each model has a removable eyepiece, so any TICO 6 becomes a thermal monocular for glassing a field before you mount it back on the rifle.
What is Recoil Activated Video good for on a hog hunt?
It automatically starts recording when the rifle fires, so your shots are captured without fumbling for a button — useful for confirming hits and reviewing the night afterward through the ATN Connect 6 app.
Will a heavier clip-on throw off a lightweight hog rifle?
The 640x512 is the heaviest at 1.24 lbs, still modest for a clip-on. On a lively carbine the 256x192 at 1.12 lbs balances best, but all three are designed to mount forward without upsetting a typical hog setup.
