I tried the jake mobile last year, with a couple of hens in one spot the gobbler had about a dozen hens with him and didn't care about the jake mobile. I traded it for a b mobile. I went to a different spot and killed a gobbler on Monday that had 10 3/4 beard 1 1/8 spurs. I used b mobile that following Saturday at the same spot and litterally had another bird run in to my calling throwing dirt behind him, but when he saw B he stopped imediately like he was feeding and left the field. This year i put a real fan on a hinge to make him like the killer b maybe dropping his fan will help.
