Ok bowhunters come on now. Get a regular 9volt big flashlight and trail the deer. If you make a good hit its easy. If need be get a coleman lantern and track the deer. No need for these 50 to 100 dollar lights. I just cant see paying the money for all these expensive lights that wont do any better than a flashlight or a lantern.If your crawling around on the ground searching for blood, then your hit was poor. I mean I track every deer Ive shot and only one has given me trouble finding it, but I still found it with a regular flashlight. I dont know why hunters waste their money on stuff like this. Its foolish. Thats my opinion and Ive tracked many many deer with a regular flashlight. Sorry I guess Im old school...
