I'll play.
Ran into some hunters this fall who had thermal imaging devices not on their gun.
Thermal monocular or binocular. I had been scanning a hillside I'm very familiar with for approx 15 mins in the daylight and had not seen anything yet.
They pull up and in about 30 seconds get a thermal reading some 800 yards away. They put away the thermal and then pull out the alpha glass on tripods to identify their thermal reading.
Chatted with them for a bit as they were really nice guys. Even showed me video of some very impressive deer they had spotted using their thermal imaging during the day.
Claimed that sometimes even with two or three of them set up with their alpha glass that it would take 10-15 mins to finally see what their thermals picked up in seconds.
Automatically my mind went to Greenhorn and the increased ability of that lucky bastard to pick out yoga girls and nude sunbathers while hunting/scouting If he had one at his disposal.
Guess I don't know what the advantage of having a thermal for big game hunting would be.
