The best thermal clip on for hunting is the one that lets you keep the rifle you already trust. Instead of buying a dedicated thermal scope and starting from scratch, a clip-on mounts in front of your zeroed day scope and turns it into a thermal setup after dark — then comes off in the morning and you are back to your normal rig. No re-zero, no second rifle, no learning a whole new optic. The ATN TICO 6 384x288 is our all-around pick because it balances a sharp picture, real reach and light weight for a full night in the field. Here is how ATN's current clip-ons stack up for hunting.
Best long-range: ATN TICO 6 640x512 1-15x — the highest resolution and 3500m detection for wide-open ground.
Why a clip-on at all: both mount in front of your zeroed day scope, so you hunt at night without swapping optics or re-zeroing.
Why ATN's 6th-gen TICO 6 clip-ons work so well for hunting
A thermal clip-on earns its place because it adds night capability to the rifle you already shoot well. The TICO 6 mounts ahead of your day scope with the included Quick Detach Mount, so your day optic and its zero stay exactly where they were. That is the whole point: you are not learning a new reticle or re-confirming a zero in the dark. Both TICO 6 models here share the traits that matter afield — a 50Hz refresh rate that keeps a trotting hog smooth instead of smeared, SharpIR image enhancement for a cleaner picture, six color palettes so you can switch to whatever contrast reads best that night, and IP67 waterproofing for dew, rain and creek crossings. They also double as handheld monoculars once you pull the eyepiece, so the same unit scouts a field before you ever settle behind the rifle. Only ATN's current 6th-gen clip-ons are considered here; older discontinued units are left out.
Best overall for hunting: ATN TICO 6 384x288
The ATN TICO 6 384x288 is the best all-around thermal clip on for hunting because it hits the middle of every trade-off. The picture is sharp enough to identify game at real hunting distances, the 2710m detection covers most fields and tree lines, and at 524 g it does not turn the front of your rifle into a fishing pole.
A picture that reads at hunting distance
The 384x288 sensor is like the jump from standard definition to HD — more dots in the frame, so a coyote at the far side of a field shows shape and movement instead of a fuzzy smear. Because it pairs cleanly with a 1-12x day scope, you can push a bit of magnification and still keep a usable image. A <=18mK NETD keeps faint heat visible when the air turns damp.
Keeps your zero, all night
Mount it in front of your day scope and your zero does not move — you aim with the same reticle you already know. The 50Hz refresh keeps running game smooth, and roughly 8 hours on a swappable 18650 battery covers a long sit or a walk-and-stalk night. Recoil Activated Video saves the shot automatically.
A night that plays to its strengths
Picture a typical hunt: you glass a field edge, catch a warm shape moving along the tree line, and switch palettes to whatever gives the cleanest contrast that night. The 384 reads the animal well enough to confirm it is a hog and not a stray dog, you settle behind your familiar day reticle, and the 50Hz refresh keeps the picture steady as it feeds toward you. That is the everyday job this model is tuned for — not a single hero distance, but the whole range of shots a real night throws at you. Twin its handheld-monocular mode with the rifle mount and you can scout the field first, then clip it back on and hunt with the same unit.
Who it's for: the hunter who wants one clip-on that handles hogs, coyotes and general night work without overthinking it. Who it's not for: someone who only ever shoots wide-open country at the far edge — the 640 reaches further.
Best long-range: ATN TICO 6 640x512
The ATN TICO 6 640x512 is the pick when your shots stretch across open ground. Its higher-resolution sensor and larger 50mm lens push detection to 3500m and pair with a 1-15x day scope, so you can reach out and still positively identify what you are looking at.
More resolution, more reach
The 640x512 sensor carries far more detail than the 384, which means you can pair it with a higher-power day scope and still read the picture at distance. On flat farmland or big pastures, that extra reach turns a guess at the tree line into a confident identification.
When the extra reach earns its keep
On a wide agricultural field, animals often show up far out and stay there, working the crop while they decide whether to close the distance. The 640's extra resolution lets you positively identify them at that range and follow them cleanly as they move, so you are ready when they finally step into your shooting lane. The step up in price and a few extra ounces on the muzzle buy you that early, confident read — worth it when your ground genuinely opens up, unnecessary when it does not. Like the 384, it runs a 50Hz refresh, doubles as a handheld monocular, and is fully waterproof.
Who it's for: open-country hunters who value maximum reach and detail. Who it's not for: tight timber and close work, where the 384 saves weight and cost for no real loss in performance.
How to choose a thermal clip on for hunting
Match the clip-on to your ground and your day scope. Because both units keep your zero and share the core feature set, the real decision is reach versus weight and cost. Work through these:
- Your typical distance — timber and short fields are comfortable for the 384; wide pastures reward the 640's extra reach.
- Day scope pairing — the 384 pairs best up to 1-12x, the 640 up to 1-15x, so match the clip-on to the magnification you actually run.
- Resolution — 640 lets you zoom further before the image turns blocky; 384 is plenty for most hunts.
- Weight — the 384 is lighter on the muzzle, which matters on a long walk-in or a lot of offhand shooting.
- Battery — both run most of a night; carry a spare 18650 either way.
- Mounting — both include the Quick Detach Mount, so you can pull the clip-on and be back to your day rifle in seconds.
How we picked these ATN thermal clip-ons for hunting
We judged only ATN's current 6th-gen TICO 6 clip-ons against what a hunting add-on actually has to do: keep your day-scope zero, show enough detail to identify game at your real distances, and last a full night. We weighed sensor resolution, NETD for damp-air performance, detection range, the 50Hz refresh that keeps moving animals smooth, weight on the muzzle, and battery life. The honest trade-off is reach versus weight and cost — the 640 sees further and holds more detail but rides heavier and costs more, while the 384 covers the vast majority of hunts for less. Neither is the right call for someone who wants a purpose-built dedicated thermal scope rather than an add-on. This is an in-house comparison of ATN's own line, not an independent lab review, so match the specs to your ground before you decide.
Frequently Asked Questions
What is the best thermal clip on for hunting?
The ATN TICO 6 384x288 is the best all-around pick. It clips in front of your zeroed day scope so you keep your zero, gives a clean thermal picture with 2710m detection, and runs about 8 hours on a swappable battery. Open-country hunters who need more reach should step up to the TICO 6 640x512.
Do I have to re-zero my rifle when I use a thermal clip-on?
No. A clip-on mounts in front of your existing day scope, so your day optic and its zero stay exactly where they were. You aim with the same reticle you already know, then pull the clip-on in the morning and your rifle is back to normal. That is the main reason hunters choose a clip-on over a separate thermal scope.
How far can the ATN TICO 6 detect game?
The TICO 6 384x288 has a detection range of about 2710m, while the higher-resolution 640x512 reaches around 3500m. Detection range is how far the sensor picks up heat, not your shooting distance, so both give you plenty of margin to spot and identify game well before it is in range.
Can the TICO 6 be used as a handheld monocular too?
Yes. Both TICO 6 models have a removable eyepiece, so you can pull the clip-on off the rifle and use it as a handheld thermal monocular to scan a field or tree line before you set up. That flexibility means one unit both scouts and mounts, which is handy on a walk-and-stalk hunt.
Which TICO 6 should I pick for timber versus open fields?
For tight timber and shorter fields, the 384x288 is the smart choice — lighter, easier to handle, and more than enough resolution for close work. For wide-open pastures and farmland where shots stretch out, the 640x512 gives you the extra reach and detail to identify game at the far edge.
Is a thermal clip-on tough enough for real hunting weather?
Yes. Both TICO 6 clip-ons are IP67 waterproof, so dew, rain and a creek crossing are not a problem. They also carry 64 GB of storage and Recoil Activated Video, which saves your shot automatically, and pair with the ATN Connect 6 app over Wi-Fi for reviewing footage in the field.
Want to hunt at night without giving up the rifle you already trust? The ATN TICO 6 384x288 clips in front of your day scope, keeps your zero, and turns your everyday setup into a thermal rig after dark. If your ground opens up and shots stretch out, compare it against the rest of ATN's thermal clip-ons and pick the reach that fits. Either way, you keep one rifle and gain a whole extra half of the day.
