That looks like an excellent unit, Dave. I've seen that one before and might check it out.
State game laws direct that for a device to be used on public land, it cannot project any visible light or shape onto the target for hunting, so since a lot of my hunting is on public lands I guess that puts me in search of "green light".
Honestly, I'd probably buy something dopey and expensive just because it's "cool", but I have to be a little bit practical, or I'll never be able to explain it to "You-know-who".
