... or any detector for that matter. >:\ Just when I feel like I am getting comfortable with the Etrac I get skunked. Went to a place I have found a silver half, couple mercs, etc... Not even a zincoln. Went to 2 other nearby parks both at least 50 years old. Not even a zincoln. I sure can pinpoint those smashed screw caps though! Actually pinpointing is a breeze with Etrac. I tried multi tone, 4 tone, 2 tone, cond, fer, open screen, choked screen, man sens, auto sens, corrected for ground several times, slow pace, crawl, etc... Nada. Signals everywhere but even the few I dug I had to force a good signal. Maybe it was just a freak day with nothing under the coil? First time I can ever remember going out for 4-5 hours and getting absolutely nothing. Wife snuk a penny out in front of me and I did hit that.
