Not as good as it should be - ATN ThOR-HD 2.5-25x 50 mm Thermal Imaging Rifle Scopes

Thought I would give an honest review for the Thor-HD 640-480, This is my second thermal scope. the first was an Armasight Zeus, 2015.
first off, the buttons are difficult to manipulate. Totally impossible to use with gloves. To power up you must depress and hold the power button a few seconds. And something they don't mention on any of the advertisement, you must do a NUC every time it is powered up. Which requires an additional press of the power button. (( and the cover must be on before the NUC )). I thought the resolution was not as good as my 2015 model Armasight Zeus 160x120 30hz. the most annoying problem is the eye relief. Nearly have to have my eye touching the scope to see all the display. Hello scope burn. Had to mount it 1 1/2" high with risers to allow proper eye relief. The good, the digital zoom worked well thru 10x, after that it is useless. Was able to identify a Cow clearly at 650. The digital recording was a nice feature. The Rangefinder is a bit iffy. Takes several steps to get a range, it does not happen very fast. Have not tried the profiles with the ballistic calculator. The Menu system is fairly easy to access and program. The Phone app is a bit finicky but does work and you can see a live feed of what the scope is seeing, and you can make adjustments from the app. I have had the unit for a short time so its still up in the air if it gets returned or not. I would recommend looking at the Armasight Zeus or something in that line before I bought this scope. FYI: I sent an email to ATN customer service to get there recommendation for a scope, My Check list, Best Resolution , best Clarity, i don't really care about the frills , there response was that all their scope resolutions and clarity were the same, the difference was in the eye relief, and menu structures and optical vs digital magnification. take it for what its worth. hope this helps.
