I went hunting with a buddy last night and we got out to the blind, got setup and he turned on his scope, a sightmark wraith. Just a few hours earlier we checked zero and fouled our barrels and his scope worked fine. But in the feild at the blind it would turn on but wouldnt display an image, it had a box in the lower right corner that had a red x in it too. His scope of course was just below 50% power. Any idea what caused his issue? Just a low battery maybe? Maybe he needs to reboot it? I figured someone on here probably knows the answer, thank you in advance for any advice given.
