Grew up on NV. Excited to buy an ATN day/night scope 8 years ago. Froze, every shot out of a heavy SA 7.62. I exchanged the unit 3 times before asking for a refund. The dealer claimed he'd never heard of anyone having similar problems.
Borrowed a top of the line ATN last year. Wouldn't hold a zero. Optics weren't bad to about 125 in decent weather, but again, you couldn't count on the zero. Was an absolute nightmare to sight in during the summer.
Buddy brought a new ATN day/night scope out two weeks ago. Zero walked about 8 inches at 100. Froze, on a different 7.62.
Sighted an entry level Thor LT in for a guy the same weekend. Twice rejected the zero. Otherwise, it did OK on a .300 blk to about 70 yards. At the price point, I personally saw some utility.
It's hard to find Youtube video where the ATNs fully freeze. When they freeze on us, the unit is simply dead until fully powered down and back on.
I have a 50mm Pulsar that I swear by. It works, every time and the images are fantastic. Ironically, I pick that Pulsar for hunting over the big Trijicon Hunter, which costs nearly double.
This photo was taken on a humid night at about 150 yards:
(Of note, what you see in the scope is tremendously more clear. This image was recorded, uploaded, downloaded, emailed, saved, then uploaded to THF)
