I recently aquired the Ultimate and have noticed it picks up on the Garrett PP real bad. It is the only coil in my group that does this. I use a Whites TRX as a back-up and it doesn't talk to the Ultimate. I've tried noise canceling while the PP is on to no avail. The only thing I can do is lay my detector about and arms length away with the coil extended to the outside. Anyone else have this problem? Also can someone give me some guidance on PP with the Ultimate. It seems to have a sweet spot the entire length of the coil.
