I've changed the places I hunt and it's made my quality of finds go up a lot. Yesterday afternoon I dug a nice merc and several wheats along with some clad. I started using Angel's settings on the ETrac he listed here. Using the long tone really helps uncover the targets in the trashy old home site lots I've been hunting lately. Dug this 42 merc at 9 plus inches in the trash. It sang like a bird when the coil saw it.
