Well I guess it's time to kiss my 512 goodbye.
I have the same kill-the-battery issue RC does, *and* point of impact shift at low temp. I thought it was my ammo, when I took it out for a winter match, corrected the POI, but when I got it out next time in the spring, I was off again in a different direction with the same ammo?
I was scratching my head on that one.
But I guess I know what the deal is now. Damn thing just didn't like subzero weather.
Mine is 2006 era.
Kind of a shame, I like the damn thing.
But .. tools are tools and I can't keep something around that won't turn on when I need it. Given Illinois winters, and temperature swings we get, those sub zero POI shifts and no return to zero, are no-good, either.
