Congrats on some deep silver. I run an Etrac and I always dig the deep repeatable signals. The signals are never quite the same (sometimes higher or sometimes lower) as the signals that are just 3 inches deep. I find that I use the depth gage on the etrac a lot and I think it is pretty accurate...its a great little tool for me and my style of hunting.
Works with my Explorer also . This was one of the best tips an old Guru ever told me .
Congratulations on your finds and your advancements in becoming one with your detector MIKE54.
