The title of this thread should be deep everything! I ran the ETrac since it came out and got my hands on the GT about 4 months ago and never looked back period. The GT doesn't need a lesche it needs a stainless steel scoop to dig with. In my experience with six minelab machines and a few others the GT has beat them all in depth. It will find stuff even the ETrac won't find in heavy mineralization. The GT when ran very slow will find stuff no other detector will if you ask me. Tiny small targets to anything above. I've never seen the ETrac or Explorers or any of the Xterra's do what it is doing for me. Deep is relevant also. In black sand iron rich red clay it shut all my other detectors down. The GT when ran snails pace will find targets all over the place in this stuff. The machine will be total silent nulled out and will sound off when ran over and accepted target, anything above iron simply. Being relevant, depth is no wheres as great as in good ground, but other machines have left a bevy load of targets in the stuff I'm hunting, I mean a lot of them per they were not seeing the targets. These places have turned into my gold mine! Coins too. What made me realize this is the loads of 1970's pulltabs present. Lot's of them on hard hunted a lot places. In a time when everyone wants to know almost for certain what they are digging before they exert the energy with a lot of machines. The GT puts them to shame. They are missing great targets wanting to know, as I was, with all my other machines. The new machines with whitewalls and curb feelers and pretty screens are causing many to leave stuff in the ground. The GT will find them. Lot's of horsepower in that little blue control box, no bells and whistles.
