The best thermal optic rifle scope for you comes down to the job you bought it for. Nightly hog control on a working ranch asks for different things than the occasional predator call, and paying for a flagship you use twice a year makes no sense. This comparison puts two ATN 6th-gen ThOR 6 thermal scopes head to head by use case — the all-around 640x512 2-16x against the value 384x288 2.5-20x — so you match the scope to the work.
For a thermal optic rifle scope, the ATN ThOR 6 640x512 2-16x is the pick for regular, mixed-use hunting — its higher-resolution sensor and detection range cover hog control, predators and ID at distance. The ThOR 6 384x288 2.5-20x is the value choice for lighter, close-range use. Choose the 640 if you hunt often, the 384 if you hunt occasionally and close.
How the ThOR 6 640x512 2-16x works
The ATN ThOR 6 640x512 2-16x pairs a high-resolution 640 sensor with a low 2x base and a roughly 3100 m detection range. The extra pixels mean an animal stays sharp as you zoom to identify it, and the wide base helps you scan and swing on moving hogs. For someone out several nights a week, that resolution is the difference between confidently calling a target and second-guessing it in low contrast.
How the ThOR 6 384x288 2.5-20x works
The ThOR 6 384x288 2.5-20x runs a 384 sensor with a slightly higher 2.5x base and detection to about 2300 m. It carries the same 6th-gen features — SharpIR, Recoil Activated Video, Picture-in-Picture, six palettes — at the value tier and the lightest weight of the pair. For close-to-mid shots taken now and then, its image is plenty, and it's the easiest on both your shoulder and your wallet. Because it shares the same interface and controls as the 640, a hunter who later steps up won't have to relearn anything, which makes it a sensible starting point as well as a value pick.
When to choose the 640x512 2-16x
Choose the 640x512 2-16x when hunting is a routine, not an occasion. Nightly hog control, predator calling across varied ground, and any situation where you need to identify targets at real distance all reward the higher resolution and longer reach. If a thermal scope is a working tool for you, this is the one that pays for itself in confident shots. Volume matters here: when you glass a lot of animals night after night, the small edge in clarity turns into far fewer second-guessed targets and fewer wasted stalks over a season, which is exactly what a serious working hunter is buying.
When to choose the 384x288 2.5-20x
Choose the 384x288 2.5-20x when your use is lighter and closer. Occasional weekend hog hunts, close stands, and hunters who want a full-featured 6th-gen scope without stepping up to the flagship tier are the sweet spot. You keep every important feature and simply accept a shorter detection range that most close-range shooting never tests.
It's worth being clear about what 'less resolution' actually means day to day. At the close-to-mid ranges this model is built for, a 384 sensor still resolves a hog or coyote plainly — the missing pixels only start to matter when you push far past where you'd realistically shoot. So for a hunter whose ground is tight and whose trips are occasional, the 384 isn't a downgrade you'll feel; it's simply the right amount of scope for the job, with the weight and price to match. The slightly higher 2.5x base even trims a little bit of the scanning width in exchange for a touch more reach when you do need it.
Our recommendation
For most buyers who hunt regularly and across mixed ranges, the ATN ThOR 6 640x512 2-16x is the pick: the higher-resolution sensor and longer reach earn their place when you're out often. If your use is occasional and close, the value 384 model is the honest, lighter, more affordable choice. Compare both, and the flagship 3-24x, in the ATN thermal scope category before deciding, and be honest with yourself about how many nights you'll really be out.
How we compared them
We compared these two scopes strictly by use case — how often and at what range you actually hunt — since that's what should drive the choice. Our yardsticks were sensor resolution (identification confidence), detection range and magnification (reach), NETD (contrast), refresh rate (tracking) and weight and battery (carry and endurance), each weighed against frequent-versus-occasional use. Only ATN's current 6th-gen line was considered. This is an in-house comparison of ATN's own scopes, not an independent lab review, so match the specs to your real schedule. The honest trade-off: the 640 costs more and weighs a touch more; the 384 gives up long-range detection. Who neither is for: long-range open-country specialists, who should look at the 3-24x flagship instead.
Frequently Asked Questions
Which ATN ThOR 6 is best for frequent hog hunting?
The 640x512 2-16x. Its higher-resolution sensor and longer detection range give you confident target identification night after night across mixed terrain, which matters when hunting is a regular routine rather than an occasional trip.
Is the 384 model good enough for a thermal optic rifle scope?
Yes, for close-to-mid-range and occasional use. The ATN ThOR 6 384x288 keeps the full 6th-gen feature set and enough detail for short shots, at the value tier and the lightest weight. It simply has less reach than the 640.
What's the main difference between the two scopes?
Sensor resolution and detection range. The 640x512 holds more detail and reaches farther (about 3100 m) for identifying targets at distance; the 384x288 is aimed at closer ranges (about 2300 m) at a lower price and lighter weight.
Do both scopes have Recoil Activated Video?
Yes. Both include Recoil Activated Video, which automatically records the moments around your shot, along with SharpIR enhancement, Picture-in-Picture and Zeroing Freeze. The feature set is the same; the sensor and reach differ.
Which is lighter to carry on long walks?
The 384x288 2.5-20x at about 790 g, slightly lighter than the 640 model's 830 g. For hunters who cover a lot of ground on foot, that small difference plus the lower price makes it an easy value choice.
Can I upgrade features later, or is it all in the sensor?
The core capability is set by the sensor and lens you buy, since resolution and detection range are physical. Software features are shared across the line, so the real decision is choosing the sensor and reach that fit how you hunt.
Match the scope to the work, not the marketing. If you hunt often and across ranges, the ATN ThOR 6 640x512 2-16x is built for it; if your nights out are lighter and closer, the value 384 model does the job for less. Line them up next to the flagship in the ATN thermal scope lineup and pick the one that fits your real hunting schedule.
