Rob, you talking about the original "tracer nock" activated by magnet?? i wanna say they sold out or something last year..??
maybe the new ones arent the same??
i have/had some of the "smart tracers"...i loved them...they worked great for me...i just ruined them all by shooting groups....normally if i shot groups at 40+ i dont have to worry all too much...but put a lighted nock to focus on and i'll hit it once in a while lol...
never got around to replacing the broken housing and nocks...never thought that i might not be able to now anyways......
but never had a problem with them...heck, 75% or more of the time they came on when i didnt have a magnet on my riser!
