I have been useing Lumenocks with mixed success... They are great when they work. If any of you saw my hunt on this years season of Whitetail addictions I shot a 14 pointer with Lumenock and the footage is awesome. But when you see hunts like that, what you don't see is all the shots where the lume never lit, or is dull or dead from turning itself on.... A guy on my prostaff is useing tracer's and his footage / results seem error free. I am going to try tracers this year.
