Thanks for the replies. I've read where the "tube" in like a PVS 14 can get spots like a dead pixel of sorts, I'm guessing that comes from use. May be just like dead pixels, just bad luck... 😀
Didn't know if there was something similar in the thermal sensors.
I've decided with the amount of use I'll likely put something through over the course of a couple years, some of you regular night stalkers will do the same in a couple of months. Now I'll worry about how much to spend on one...
