I used my new 6" coil with my safari and the machine acted up. When I started the machine it started slow and the screen with difficult to see. I had to change the contrast to see the display but the machine was still slow. Within a few minutes my headphones died. Needless to say I was not happy. Also, the target ID was completely off and the machine was "beeping" at anything. I shut down the safari and reconnected the stock coil and no problems but my headphones are still dead. Has anyone had this happen?
