Regarding PRPC, Sawman and I asked how late we could be out shooting for testing and sighting in NV/thermal and were told 9pm. It was somewhat eye-opening, trying Sawmans' green laser light...I could not see it via my scope...not enough light gathering ability and/or it may have been my poorer vision. I was able to eliminate that from night hunting consideration for me.
Have since made a day time target for sighting in thermal in bright sunlight that works perfectly. Black poster board with small square of aluminum tape in the middle. Set facing the sun, the black is heated up and the aluminum reflects the sun, keeping it cooler. Set thermal to black hot vs white hot, and you have a small white square in the middle of black to zero on. Won't work on a cloudy day. No need for hand warmers to shoot at or a torch to heat up metal or frozen water containers to shoot at. To repair the center, just put another piece of aluminum tape over the old piece.
