Tortuga, you're absolutely right, it's annoying when you go to dig a target and the cord pulls at your head. I've seen alot of threads about fm transmitters and bluetooth but nothing that seems to really work the way we want it to. I wonder what type of transmitter/reciever the 7000 uses? The spirit eq battery system in Australia has a wireless link built in also but both systems seem more robust than a simple audio transmitter from radio shack
