I was wondering if anyone can fill me in on the sniper coil for the atp. I want to do more tot lot hunting but with the 8.5x11 coil in my machine i cant get within a foot and a half of any play equipment without the atp hitting a signal. Can i get closer with the sniper coil? I want to get right up tight to the equipment and fences. I just dont want to waste the money if there isnt a difference on how close i can get. Thanks.
