The best thermal clip on hog hunting setup solves a problem every hunter with a nice day scope runs into: you do not want to give up the scope you already trust and zeroed, but you still need to see hogs in the dark. A clip-on fixes that. It mounts in front of your existing day scope, turns it thermal, and keeps your familiar reticle and zero. When the sun comes up, you pull it off and your rifle is back to normal. The ATN TICO 6 640x512 is the flagship of this line, and this roundup is organized around one idea: getting the most range and clarity out of a clip-on without ever touching your zero.
Best value: ATN TICO 6 384x288 1-12x - lighter, still Full-HD, plenty of range for most hog fields.
Best long-range: the 640 model again - its 50 mm lens and high-res sensor stretch a clip-on further than anything else in the line.
Why ATN's 6th-gen TICO 6 leads for hog clip-on setups?
The TICO 6 leads because it adds thermal to the rifle you already shoot without asking you to re-zero or learn a new reticle. A clip-on reads heat and projects that image through your day scope, so a warm hog appears right where your crosshair already lives. Your zero stays put because the clip-on sits ahead of the optic, not in place of it. The TICO 6 640 backs that with a big 50 mm lens and a 640x512 sensor - more dots in the picture, so pigs stay crisp when your day scope magnifies them - plus SharpIR AI enhancement, a Full-HD display, a 50 Hz refresh for smooth motion, and Recoil Activated Video to capture the shot. A clever bonus: pull the removable eyepiece back on and it becomes a handheld monocular for scanning before you settle in. Detection past 3500 m means you will spot hogs long before they are in range.
Best overall: ATN TICO 6 640x512 1-15x
The ATN TICO 6 640x512 1-15x is the best thermal clip on for hog hunting because it stretches a clip-on's reach and clarity to the top of the line while leaving your day scope untouched. The 640x512 sensor holds the most dots of any TICO, so when your day scope zooms in, the thermal image stays sharp instead of turning to mush. Its 50 mm lens gathers more heat detail, pushing detection past 3500 m - you will see pigs far beyond where you could shoot them, giving you time to set up.
Keep your zero, add thermal
Because the TICO 6 mounts ahead of your day optic on the included Quick Detach Mount, your rifle keeps the exact zero and reticle you already trust. Snap it on for a night hunt, pull it off for daylight, and nothing changes about your point of impact. That is the appeal for hog hunters who have already dialed in a favorite rifle.
One device, two jobs
The removable eyepiece is the feature hog hunters end up loving most. Before you settle behind the rifle, pull the eyepiece on and the TICO 6 becomes a handheld thermal monocular - walk the property, scan the field edges, and find where the pigs are working. Once you have a group located, take the eyepiece off, clip the unit onto your rifle, and you are ready to shoot through your own day scope. That means you are not carrying a separate spotter and a separate sight; one device covers the finding and the shooting. For a flagship, that flexibility is a genuinely practical touch, not just a spec-sheet bragging point.
Recoil Activated Video and the extras
The TICO 6 640 also records your hunt through Recoil Activated Video, which starts the clip automatically when the rifle fires, so you capture the shot without fumbling for a button. Add SharpIR AI enhancement for a cleaner picture, Hot Point Tracking to keep the warmest object marked, six palettes to dial in contrast, and the ATN Connect 6 app for reviewing footage on your phone. These are the touches that make the flagship feel finished rather than bare.
Who it is for - and who it is not
It is for the hunter with a quality day scope who wants the best long-range thermal clip-on and the flexibility of a handheld monocular in one device. It is not for someone starting from scratch with no day scope and a tight budget - that hunter may do better with an all-in-one thermal scope or the lighter 384 model.
Best value: ATN TICO 6 384x288 1-12x
The ATN TICO 6 384x288 1-12x is the value pick that covers most hog fields at a lighter weight and lower step in price. Its 384x288 sensor is still plenty sharp, it runs the same Full-HD display and 50 Hz refresh, and its 35 mm lens reaches about 2710 m - more than enough for typical hog ground. At 1.15 lbs it is the lighter clip-on, easier on the barrel of a slimmer rifle.
When the 384 is the smarter buy
If your shots stay inside a few hundred yards and you pair it with a day scope in the 1-12x range, the 384 gives you nearly all of the flagship experience for less. You give up some resolution and top-end range compared to the 640, but for most pig hunting that gap never shows up in the field. It also converts to a handheld monocular just like the flagship.
Same core, lighter package
It is easy to forget the 384 shares almost everything with the flagship: the same 18mK sensitivity, the same Full-HD OLED display, the same 50 Hz refresh, the same Recoil Activated Video and Quick Detach Mount. What changes is the sensor size and the lens, which is where the reach and top-end sharpness come from. So the 384 is not a stripped-down device - it is the same clip-on tuned for a lighter carry and a friendlier price, which is exactly what a lot of hog hunters actually need.
How does a thermal clip-on actually work on your rifle?
A thermal clip-on works by sitting on the rail ahead of your day scope and feeding a thermal image straight into it, so you aim through your normal scope but see heat instead of daylight. The clip-on has its own thermal sensor and display; your day scope simply magnifies and aims at that projected picture. Because the aiming optic never changes, your zero and reticle stay exactly where you set them - the clip-on does not move your point of impact. That is the whole reason clip-ons exist: you keep the rifle you already trust and just add night vision to it. With the TICO 6 you slide it on using the included Quick Detach Mount, confirm it is seated, and hunt; when daylight comes you pop it off and your rifle is a normal day gun again. Warm hogs appear right on your familiar crosshair, so there is no new reticle to learn and no re-zeroing in the field. Understanding this is what makes a clip-on so appealing to hunters who have invested in a good day scope and do not want to abandon it just to hunt after dark.
How to choose your hog thermal clip-on?
Choose by your day scope's magnification, how far you shoot, and how much weight you want up front. Both keep your zero and double as monoculars.
- Scope pairing - match the clip-on to your day scope's zoom: the 640 is built for 1-15x optics, the 384 for 1-12x.
- Resolution - the 640x512 stays sharpest as your day scope magnifies; 384x288 is still clean at normal ranges.
- Detection range - the 640 reaches past 3500 m for open ground; the 384's 2710 m covers most fields.
- Weight - the 384 is lighter on the muzzle; the 640 adds a little for its bigger lens and reach.
- Versatility - both detach and become handheld monoculars, so you can scan on foot before mounting up.
How we picked these ATN thermal clip-ons
We ranked these on what a hog hunter actually needs from a clip-on: sensor resolution so the picture holds up when the day scope magnifies it, NETD for a clean image in humid air, detection range for open fields, lens size for light-gathering, weight on the muzzle, and battery life for a full night. Only ATN's current 6th-gen TICO 6 line was considered. The honest trade-off: the flagship reaches farther and stays sharper but weighs a bit more and costs more, while the value model is lighter and cheaper with a touch less reach. This is an in-house comparison of ATN's own clip-ons, not an independent lab test, so match the pick to your day scope and your typical distances. Who it is not for: a hunter with no day scope on a tight budget, who is better served by an all-in-one thermal scope.
Frequently Asked Questions
What is the best thermal clip on for hog hunting?
The ATN TICO 6 640x512 1-15x is the best thermal clip on for hog hunting. It mounts ahead of your zeroed day scope, keeps your existing reticle, and adds a sharp 640 thermal sensor with detection past 3500 m. It also converts into a handheld monocular for scanning.
Do I have to re-zero my rifle with a thermal clip-on?
No. A clip-on like the TICO 6 mounts in front of your day scope rather than replacing it, so your existing zero and reticle stay exactly the same. You clip it on for night hunting and pull it off for daylight without touching your point of impact.
How far can the ATN TICO 6 detect a hog?
The TICO 6 640 detects heat out past 3500 m and the 384 model to about 2710 m. Both ranges let you spot pigs well beyond shooting distance, giving you time to set up before they get close.
What is the difference between the TICO 6 640 and 384?
The 640x512 model has a sharper sensor and a bigger 50 mm lens, reaching past 3500 m and staying crisp at high magnification. The 384x288 model is lighter and less expensive with about 2710 m of range, which suits most hog fields.
Can the ATN TICO 6 be used as a handheld monocular?
Yes. Both TICO 6 models have a removable eyepiece, so they convert from a clip-on into a handheld thermal monocular. That lets you scan on foot to locate hogs, then mount the device on your rifle when you close in.
What day scope magnification works best with the TICO 6?
Pair the 640 model with a day scope in the 1-15x range and the 384 with a 1-12x scope for the best image. Because thermal detail is fixed by the sensor, staying within these ranges keeps the picture clean rather than empty magnification.
Is the TICO 6 tough enough for rough hog hunting?
Yes. Both models are IP67 waterproof and include Recoil Activated Video, so they handle wet, muddy nights and capture your shots. The included Quick Detach Mount also lets you remove and remount without losing alignment.
Already trust your day scope? Keep it. The ATN TICO 6 640x512 clips on in front, turns your rifle thermal, and reaches hogs past 3500 m - then detaches into a handheld monocular for scanning. Want a lighter, more affordable option for closer fields? The 384 model has you covered. Browse the full range of ATN thermal clip-ons, match one to your optic, and start hunting hogs after dark without giving up the setup you already love.
