When a black friday thermal scope sale narrows your choice to ATN's two 640-class ThOR 6 scopes, you do not need another list of prices - you need to know which features actually differ and which are identical. The ATN ThOR 6 640x512 2-16x and the 640x512 3-24x share the same sensor and the same smart toolkit, so most of the spec sheet is a tie. This comparison walks the two feature by feature - SharpIR, Recoil Activated Video, Hot Point Tracking, Picture-in-Picture, battery, and magnification - so you can see exactly where they part ways and stop paying for a difference that is not there.
Feature for feature, the ATN ThOR 6 640x512 2-16x and 3-24x are identical on SharpIR, RAV, Hot Point Tracking, Picture-in-Picture, and battery - they share one 640 sensor and one software toolkit. The only real difference is optics: the 3-24x reaches farther and magnifies more; the 2-16x sees wider and swings faster. We lead with the 2-16x as the everyday pick, and step up only if you truly need reach.
ATN ThOR 6 2-16x vs 3-24x at a glance
Both scopes run the same 640x512 sensor at NETD 15 mK or lower, so they see equally well - the split is entirely optics and reach. Here is where the two line up and where they diverge, feature by feature.
How the ThOR 6 2-16x works, feature by feature
The ThOR 6 640x512 2-16x gives you the full ThOR 6 feature set built around a wider view. Its 2x base magnification and 35 mm lens open up the field of view - that is how much of the scene you see at once - so you find game faster and swing onto a moving target quicker. Every smart feature rides along: SharpIR AI enhancement sharpens the picture in low-contrast air, Hot Point Tracking marks the warmest object as it moves through cover, Picture-in-Picture floats a magnified aiming window over the wider scene, and Recoil Activated Video saves each shot automatically. The 50 Hz refresh keeps a running animal smooth. Nothing about the toolkit is trimmed - you simply get it in a package tuned for speed and a broad picture.
How the ThOR 6 3-24x works, feature by feature
The ThOR 6 640x512 3-24x runs the exact same features but wraps them around more glass. The 50 mm lens and 24x top magnification push detection to 3650 m and, more importantly, let you resolve what a distant heat signature actually is before you commit. SharpIR, RAV, Hot Point Tracking, Picture-in-Picture, and the 50 Hz refresh all behave identically to the 2-16x - the software is the same. What changes is that Picture-in-Picture and Hot Point Tracking now operate over a longer reach, so at distance the extra magnification turns a far warm dot into a shape you can identify and range. The trade is a longer front end and a narrower base view you feel the moment things get close and fast.
When to choose the 2-16x
Choose the 2-16x if the features that matter most to you are the wide base view and quick handling. On the vast majority of nights you are scanning, not reaching out to the edge of a section, and the broader picture means fewer sweeps to cover the same ground and less chance of walking your eyes right past a bedded animal up close. SharpIR and Hot Point Tracking do the same work here as on the bigger scope, so you give up nothing on image quality or tracking - you simply favor speed and field of view over maximum magnification. For most hunters this is the practical everyday pick, and it is the one we recommend by default.
When to choose the 3-24x
Choose the 3-24x when the single feature you truly need is reach. If you regularly pass on a target because you could not tell what it was at distance, the extra magnification and the 3650 m detection range are the fix. The rest of the toolkit is identical to the 2-16x, so you are paying purely for the longer optics - which is worth it on open ground where positive identification at range is the whole challenge, and wasted length if your nights stay close. Be honest about how often you actually dial past 16x before you step up; the difference is optics, not features.
The features both scopes share
Almost everything, and that is the point. Both ThOR 6 scopes carry the same 640x512 sensor at 15 mK or lower, the same SharpIR AI enhancement, the same Recoil Activated Video, the same Hot Point Tracking, the same Picture-in-Picture, the same 50 Hz refresh, and the same built-in Wi-Fi with ATN Connect 6 and a Full-HD OLED display. Both run about 9 hours on two swappable 18650 cells, so a spare pair covers a full night on either model. Because the entire feature set is shared, you are not trading away smart tools to pick a lens - the decision is optics only, which keeps it simple.
Our recommendation
For most hunters watching a sale, we lead with the ATN ThOR 6 640x512 2-16x as the everyday pick. It carries every feature the 3-24x does, adds a wider base view and faster handling, and covers the close and mid-range work that fills most nights. Step up to the 3-24x only if your ground is genuinely open and you regularly need to identify game past what 16x will resolve. Either way you are on ATN's current 640-class sensor with the identical toolkit. Compare both in the ThOR 6 thermal scope category, and if you buy during a sale, buy the reach you will actually use - not the longer number for its own sake.
How we compared them
We judged these two ATN ThOR 6 scopes feature by feature, holding the shared items constant - sensor resolution, NETD sensitivity, refresh rate, and battery are identical - so the comparison isolates the one thing that changes: optics. We weighed base field of view and handling for the 2-16x against magnification and detection range for the 3-24x, measured against the way real nights run. 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 the reach you genuinely need rather than to a sale price.
Frequently Asked Questions
Do the 2-16x and 3-24x have different features?
No - the smart features are identical. Both include SharpIR AI enhancement, Recoil Activated Video, Hot Point Tracking, Picture-in-Picture, a 50 Hz refresh, Wi-Fi with ATN Connect 6, and the same 640x512 sensor. The only real difference is optics: base magnification, maximum magnification, lens size, and detection range.
Which one should I buy in a thermal scope sale?
For most hunters the ATN ThOR 6 640x512 2-16x is the better everyday buy because it carries every feature the 3-24x has plus a wider, faster view. Step up to the 3-24x only if you truly need the extra reach on open ground. Buy the magnification you will actually use, not the bigger number.
What does SharpIR actually do?
SharpIR is ATN's AI image enhancement. It cleans up the thermal picture in low-contrast conditions so a warm body in damp or hazy air still reads as a clear, recognizable shape. It works identically on both the 2-16x and the 3-24x, since they share the same processing.
Is Hot Point Tracking on both scopes?
Yes. Hot Point Tracking keeps a marker on the warmest object in the scene as it moves, which helps when an animal slips behind cover and reappears. Both the 2-16x and the 3-24x include it; on the 3-24x it simply operates over a longer reach thanks to the higher magnification.
How much farther does the 3-24x reach?
The 3-24x detects out to about 3650 m versus roughly 3100 m for the 2-16x, and its 24x top magnification resolves distant shapes better. The practical gain is positive identification at long range. If your ground stays close, that extra reach mostly adds length you will not use.
Does one have better battery life?
No, battery is a tie. Both run about 9 hours on two swappable 18650 cells, so a charged spare pair covers a full night on either scope. Battery, refresh rate, and sensor are all identical, which is why the choice really comes down to optics.
Can I record shots on both?
Yes. Both include Recoil Activated Video, which senses recoil and automatically saves a clip of the shot, plus built-in Wi-Fi and ATN Connect 6 for reviewing and sharing footage. That feature is the same on the 2-16x and the 3-24x.
Still weighing reach against handling? If you want the full ThOR 6 feature set in a wider, faster package, mount the ATN ThOR 6 640x512 2-16x; if you genuinely need to identify game at long range, the 3-24x adds the optics without changing a single feature. Compare both on the ThOR 6 thermal scope page and line the specs up against the distances you actually hunt. If you are buying during a sale, put the savings toward the reach you will use and a spare pair of cells - not toward magnification your ground will never ask for.
