DRS-TH - Sensor Sensitivity and Zeroing

This is the thermal gun camera view of a few of the shots I made yesterday while zeroing both sides of the optic (which was ... interesting, more on that in a later video).

The targets you see are at 50 yards - white paper plates, about 9" in diameter, with a 2" circle drawn in sharpie in the middle. I start at 5x digital zoom and then later fall back to 3x digital zoom. Conditions were a cool, sunny afternoon, approximately 65F, so the white portion of the plates is cool (dark), and the faint thermal signature in the middle is the black circle I drew. The background is a sheet of plywood (a bit shot up), and then the berm behind it.
