"I have used this device two times when ?I have had small blood trails and found that it helped out quite abit. It made the blood almost flourescent and almost jump off of the ground. I would reccommend it as a cool gadget for anyone at 40$."

i have had a high intensity light with interchangeable lenses for several years. It is not a Gerber. It is a high intensity 6 volt lightlike the cops use. With the blue lense it does make "the blood jump off the ground." Any small droplet oof blood on grass or leaves sticks right out. i've used mine to track night time blood trails of one huge bull elk and three deer for other folks. The police use this at indoor crime scenes to look or evidence of blood. Of course, there are those doubters, including those who are too lazy to look for the game they shot.

"But I have to raise the biiiiig BULL sighn on this one. We bought a pair to use on the military reservation where I hunt. We kill between 70 and 100 deer a year here and frequentlyhave to track them at night."

Did you ever try a really good high intensity blue light to track woundedgame at night? if you have not then i raise the BULL sign on you.
