I would love more comments from hunters who have used blood lights that works, some specific brands please. I too, are a big fan of Coleman lanterns for camping; they put out a lot of light and heat as well for winter camping. I can't see they would be particularly useful for tracking deer; seems to me you need something that throws a beam. The hydrogen peroxide idea is interesting, but if I knew where to squirt it I wouldn't have the problem. You shoot a deer fom 100-150 yards in low light from a elevated stand, by the time you get the area where you think he ran into the woods and everting looking different from ground level; there is a broad area to look for blood. A good light is a big help but a blood light that WORKS would be a huge help.
