RE: Should I believe this?
A deer's vision is it's weakest line of defense. All you have to do is remain still, spot the deer before it knows you're there,move very slowly and only when it is moving or looking away.
Millions of deer get shot every year by hunters wearing conventional blaze orange. This new product may give you a very slight advantage, but is it worth the cost, and could you gain more of an advantage by improving your hunting skills instead?
