I’ve been reading through a bunch of threads like this and it seems like the buy once cry once is the way to go.
Going to start out with a quality set of red lights (Likely wicked) and then save up for thermal.
I started off with a Gen2+ M845 and eventually sold it because I was never as successful as I thought I should be. I recently went for a walk around a friend's farm house with my new FLIR Breach and a white weapon light and had more fun/success (skunks, raccoons, rabbits) than I collectively had with just NV.
IMHO a thermal spotter (helmet mounted is awesome) with a NV clip-on is the way to go. Can't wait to get a clip-on and go calling.
