It's more programmable, for sure! IF... big IF... you learn the detector and take some time setting it up for where you hunt, you will easliy dig 10-13". I am running Magic's program. slow sweep speed and DEEP! I am in Pittsburgh, PA... lot of iron but no mineral problem. Here's a pic at an old park from the late 1800's. Unfortunately, the 'filled' it and smoothed it over, so anything old is 8"+. I hunt with a few friends. One has a Tesoro, another an F5, and another White's die-hard who has a CoinmasterGT and M6, and there is NO WAY they can hit the depths I do. They pick up some shallower clad, but NO WAY they can get the hits I do and dig he plugs I do. My TDI is off a little from the depth, but my V3i hits it nice! The pic is a 10" target at 10", and I hit them deeper too.
When running the stock programs, I seriously thought that my Etrac would SMOKE the V3i. After making that program, the V3i is a BEAST!
I am not sure if the V3i would be better for you, but I'd put my Etrac up against a MXT Pro. I hunted with a local guy in Indiana, PA about 4-5 times and he had an MXT Pro. I not only hit more silver, but the Indians and hit a sweet gold ring when we went out. I hammered my Etrac for 2 years, and tweeked Andy Sabich's programs, and heard the tones in my sleep from detecting 6 days a week, 4-8 hours a day. I have had my V3i for about 2 months now and gimme another few months and I'll SMOKE my Etrac, with confidence. I am not brand loyal at all... I am 'treasure loyal'. The V3i is pretty darn impressive! For two years I avoided White's because of the 'clunky box under the arm cuff'. I will admit I was wrong on that.
