My first detector was a Silver umax my second one is a new DeLeon . If you like your Silver umax you will love the DeLeon even more.
I use to hunt at the zinc/penny zone with my silverumax because I got tired of digging trash with it, I found alot of clad and one silver with it that way. Now I hunt with the DeLeon at just below 5 cent mark and now when I hit a target that is coin size I can confirm with the T.I.D. and decide if I want to dig that target or not. I believe I will gain some depth like that in the discrimnate mode.
To me it operates very much like a silverumax except better because of the larger coil, T.I.D. and the adjustable threshold.
