Local park, 30 minutes before lawnmower arrived. Lots of bottle caps and pull tabs, but also a nickel and a large earring marked 925, so found some silver. Used 12x10 coil, Gain low, Sensitivity at default level, Tone ID. There is no depth readout when pinpointing but circle will diminish in accordance with size or depth of the target. I haven't tried correlating diameter of circle to inches deep. Lots more to discover with this detector but after 1 hour, this machine is worth keeping. I still have 3 Garretts, 2 with 4" coils available, when I tire of the 12x10, and it seems heavy.
