I found a very thin copper coin at about 25cm in heavy terrain. Sovereign located it very strong, and cesar not so good (it wanted the coil to be very close to earth so to locate it). On air test cesar is better but at ground Minelab is better. But it is fantastic for his money.
I tried both with 15" coil. Maybe another time to test both with smaller coils, for the time i have not yet smaller coil for the Sovereign.
Regards
