Mattson Munitions is certainly on the right track with this breakdown, but even scopes of the same resolution, are not the same when in the field. That's why at Hidden Ponds we only use the absolute best thermals on the market, RIX Optics, because when you want clarity in the reticle, LRF, ballistic data automatically calculated, and high quality video to prove your hunting stories true, RIX stands atop the mountain.
640 vs 1280 Thermal Resolution — What’s the Difference?
Higher resolution usually means a cleaner image, but it doesn’t automatically mean it’s the right thermal for every hunter.
A 384 thermal will work. You can detect heat and hunt with it, but you lose detail faster, especially at distance or when zooming.
A 640 thermal is the sweet spot for a lot of predator hunters. Better image, better identification, and it holds together much better when you zoom.
A 1280 thermal is the next step up. More detail, less pixelation, and a wider, cleaner picture — especially useful in wide-open country.
But resolution is only part of the equation.
You also need to look at:
Lens size
Base magnification
Field of view
Detection range
Battery life
Weight
Reticle options
Laser range finder
Ballistic calculator - This part matters in North Dakota.
At night, distance can be deceiving. A coyote that looks 175 yards away might be 300+. A built-in laser range finder helps take the guessing out of it.
A ballistic calculator, when set up correctly with your rifle, bullet, velocity, and zero, can give you a better hold point instead of guessing.
So when someone asks, “Do I need 640 or 1280?” my answer is usually: It depends how you hunt.
For most hunters, a good 640 is probably the best balance of price and performance.
For guys hunting big open country who want the clearest image possible, 1280 makes sense.
The best thermal isn’t always the most expensive one — it’s the one that fits the way you actually hunt. That’s what we try to help people sort through before your purchase.
