thanks guys . i was working in a sporting goods store running the archery shop and we had a big hunting show every year. well the guy from extreme demintions wildlife calls was there . i have one of the calls and i proceded to tell him my idea for making it to where you could use the memory sticks in it like a camera so you could use the same call for varmints or deer or whatever. he laughed and said it was a novel idea. at the time they had totaly differant units for each type of hunting. well a few months later we get a catalog of whats to be new the next year and right there is my idea. exactly as i had told him to the exact degree. so this time i will not tell anyone before i get it legal.thanks again.
