I have had an Explorer ll for 12 months bought used. Tried learning this machine on and mostly off. Lately I have been able to operate it in basic Smart mode but when it comes to pinpointing the target it is a dissaster! For every coin I find I leave the next 3 targets in the ground. I mostly locate with a long screwdriver, I'm too embarrassed to dig craters everywhere even thou I fill them back in. It is a stock 10" double "D" coil. I'm used to using my MXT with a excellerator 5/7 coil. I sure could use some advice or if anyone lives in the Lakeland Fl. area maybe we could hook-up. Bob
