I agree with rack! 90% of whats in magazines and on TV outdoor shows is just gimicks on what you really don`t need![:'(] every thing is commercialize these days. If a dollar can be made? Someone will try to make it! by creating some crapy gimick that attracks hunters in beleaving that if you by my product your going to be a very succesfull![:'(] We have all bought into these type gimmicks from time to time to find out most of this type crap we never needed to begin with. I fell for a lot of the old stuff back in the early 80`s but it does`t compair to today! Open any hunting mag, or watch any hunting TV show most is advertising on the latest and greatest gimicks.
