You have probably already searched thermal scope dealers near me, seen where you can buy, and realized the store list does not answer the only question that matters: which ATN ThOR 6 do you actually carry to the register? If you have narrowed it to ATN's 640-class scopes, it comes down to two models and one thing about your land - close cover or open ground. The ATN ThOR 6 640x512 2-16x and the 640x512 3-24x use the same excellent sensor, so this is not about image quality. It is about terrain. Sort that out here and you can order direct from ATN or ask an authorized dealer for the right model with zero guesswork.
For close cover and brush the ATN ThOR 6 640x512 2-16x wins on its wider base view and faster handling. For open ground and long lanes the 640x512 3-24x wins on reach, with a 3650 m detection range and higher magnification for positive ID. Same 640 sensor, different terrain - decide by your land before you buy anywhere.
ATN ThOR 6 2-16x and 3-24x compared before you buy
Both scopes use the same 640x512 sensor at NETD less than or equal to 15 mK, so they see equally well - the split is optics and reach. Here is how the two line up before you settle on which one to buy.
Why the 2-16x suits closer ground
The ThOR 6 640x512 2-16x earns its keep where sight lines are short and everything happens quickly. Starting at 2x, it shows you a broader slice of the woods than the 3-24x does, and that broader slice is the difference between finding a hog the instant it breaks a thicket and losing precious seconds panning around for it. The compact 35 mm lens keeps the barrel short, so the rifle points where you look without a fight. Down in brush, timber, and creek bottoms, a scope that gets on target fast beats one that sees a mile. If your shots arrive close and without warning, this is the glass that keeps up.
Why the 3-24x suits open country
Distance is the whole point of the ThOR 6 640x512 3-24x. The larger 50 mm objective gathers more of the scene's heat, and the 24x ceiling lets you actually make out what a signature is at 3650 m instead of just noting that something warm is out there. Across cut fields, pasture, and long lanes, that combination turns a faint smear into an animal you can name and range. You pay for it with a longer barrel and a tighter base view that feels sluggish up close. But on wide country, the alternative is creeping up on things that turn out to be cattle or a sun-warmed rock, and the 3-24x saves you those wasted stalks.
Reach for the 2-16x when cover closes in
Choose the 2-16x if most of your nights happen inside a couple hundred yards: working timber, walking brushy fence lines, hunting creek bottoms, or clearing a wooded property where targets appear close and you need the scope on them instantly. For that kind of ground, a broad view you can get on target fast beats top-end zoom you would seldom reach for, so it is the model most local buyers should ask an authorized dealer to show them first. The broader picture also makes scanning less tiring - you spend most of a night searching, not shooting, and fewer sweeps to cover the same ground means less chance of walking your eyes right past a bedded animal at close range. For mixed and tight terrain, this is the practical everyday buy. If you plan to buy in person, this is the one worth handling at a counter: shoulder it, sweep it across the shop, and you will feel how fast the wider view finds a target - a test that matters far more than any number a dealer can quote you.
Reach for the 3-24x when the land opens up
Choose the 3-24x when distance is the whole challenge - open agricultural fields, pasture flats, ridgelines, or any setup where you must identify a target before you move on it. The longer reach and finer detail at range justify the extra length and slightly slower swing. If you keep passing on shots because you could not tell what a heat signature was at distance, this is the scope that fixes it. That range confidence is the real payoff: when you can positively identify at distance, you stop wasting nights easing up on cattle, dogs, or a warm rock, and you take only the shots that count with a clear picture of what is in front of you. When you shop for it, ask to look through it at the farthest object in the store; even indoors you can judge how cleanly the higher magnification resolves detail, which is the whole reason to pay up for reach you will actually use on open ground.
Buying either model: what stays the same
Whichever way your ground points you, both ThOR 6 scopes give you the same core toolkit, so you never trade away features to pick a lens. Each runs the same 15 mK-class sensor, a 50 Hz refresh for smooth tracking of moving game, SharpIR image cleanup, Hot Point Tracking, Picture-in-Picture, and Recoil Activated Video that saves every shot. Both carry Wi-Fi and ATN Connect 6 for reviewing footage, a Full-HD OLED display, and about 9 hours of runtime on two swappable 18650 cells, so a spare pair covers a full night on either model. That shared foundation is why this really is a terrain decision and nothing more. That shared foundation also makes buying simpler: whether you order direct from ATN or pick one up from an authorized dealer, you are getting the same firmware, the same warranty support, and the same app ecosystem, so your decision stays about lens and reach rather than where the box came from.
Our recommendation
Most private land is a patchwork, so our default is the ATN ThOR 6 640x512 2-16x. It carries the full 640 image, gets on close targets in a hurry, and still reaches out plenty far for the mid-range shots a mixed property throws at you. Reserve the 3-24x for land that is honestly open and long, where you regularly need to identify before you move. Tighter budget and close shots only? The 384x288 2.5-20x runs the same feature set for pest work. Line all three up in the ThOR 6 thermal scope category, lock in your pick, and grab it wherever suits you - ATN direct or an authorized dealer both put the identical scope and warranty in your hands.
How we compared them
We judged these two ATN ThOR 6 scopes against the one variable that separates them - terrain - using base field of view and handling speed for close cover, and magnification plus detection range for open ground. Both were held to the same sensor resolution, NETD sensitivity, refresh rate, weight, and battery, so the comparison isolates optics rather than image quality. Only the current 6th-generation line was considered. This is an in-house comparison of ATN's own scopes, not an independent lab review; the honest caveat is that neither is ideal at both extremes, so match the choice to where you actually spend your nights - and confirm any seller is authorized before you buy.
Frequently Asked Questions
Should I buy from a local dealer or direct from ATN?
Either works, and when the dealer is authorized the product and warranty are identical. A local counter lets you handle the scope before you pay; buying direct from ATN is often simpler and keeps you close to the maker's own support. Decide on the 2-16x or 3-24x first, then choose whichever source is easiest.
Is the 2-16x or 3-24x the better buy for my land?
It depends on terrain, not price - both are current 640-class scopes. Pick the 2-16x for close, brushy, fast work and the 3-24x for open ground where you need to identify targets at distance. Settle that before you contact any dealer.
Do the two scopes see equally well?
They do. The same 640x512 core sits behind both at NETD less than or equal to 15 mK, so neither shows a warmer or cleaner picture than the other. Everything that separates them is glass: how wide the base view opens, how far the zoom climbs, and how far each reaches.
Which has the wider field of view?
That belongs to the 2-16x, which starts at 2x behind a 35 mm lens. The lower base zoom opens up the picture so you sweep more country per glance and land on nearby targets quickly - ideal for tight timber and heavy brush.
How much farther does the 3-24x reach?
About 3650 m for the 3-24x against roughly 3100 m for the 2-16x, and the 24x ceiling pulls far-off shapes into focus better than 16x can. In the field that extra reach means you can tell what a distant signature is, which matters far more than the headline distance figure.
Are they the same weight?
Both land right around 830 g on paper. What differs is the balance: the 3-24x hangs a bigger 50 mm objective out front, so it sits a little nose-heavy and comes around a touch slower than the trimmer 2-16x, despite matching on the scale.
Torn between reach and quickness? Wooded, close-in ground calls for the ATN ThOR 6 640x512 2-16x and its wide, fast-handling view; wide-open country calls for the 3-24x. Put them side by side on the ThOR 6 thermal scope page, weigh the base field of view against the land you hunt, and once you have chosen, buy that model from ATN directly or an authorized dealer near you. Settle the scope by terrain and where to buy sorts itself out.
