Why would I need a lighted nock? Because I'm blind in one eye, but I can still hit bullseyes all day long. It's hunting that arrow down in the brush that I need help with. If I couldn't make a clean shot, I'd just hang it up, but I can. What I have problems with is that peripheral vision to hunt down the arrow if I miss. Chasing a kill would certainly be helpful as well. I'm after coyote most of the time, not deer. Dead dark when I'm hunting. Completely legal where I am, and we get asked to do it constantly by the game wardens.
