I am a long time hunter. Last year wounded a deer bow hunting and after tracking for 3/4 of a mile, it occurred to me .... "this would be a lot easier with one of those tracking lights". So now I'm on a mission, I want one of those tracking lights, but the problem is I don't know much about them. Does anyone have any experience with them? I've seen them online from $30 to $100 and I just want to know if anyone has any recommendations? Any help is much appreciated. Thanks in advance and God Bless.
