A few years back the Etrac used to be my only machine, i really enjoyed using it but i knew i was missing loads in iron. Since then i have bought and tried many good machines and only the past few days my detecting buddy loaned me his old Etrac to play with in my test garden.
Well the Etrac still hits well on large silver coins, and gets pretty good ID till about 90% of it's depth in my soil, it's about the same as the Deus on clean solo targets, but throw a nail into the mix and the Etrac poo's it's pants on ID and separation.
When i try my Signum with stock 7khz coil vs Etrac on deeper targets, just where the Etrac is at it's depth limit and ID is gone AWOL, the Signum still hits hard with a dig me signal, plus it will separate and recover faster, it's just that 10% better all round than the Etrac, deeper than the Deus but it doesn't do in nails what the Deus can.
