The other day I dug a 1806 1/2 Reale @ 3". The reason I am writing this is because it came in @ 12/43 which I consider the Memorial penny range or I had thought that with my Etrac. This is a different machine and you can't expect silver to ring up high like it did with the other Minelab units. I am hunting in Ferrous Coin and my cut off for the highest tone is 44 and up. We all need to be very cautious when we play the dig or not to dig game. This was a very old site and that would have me digging any target like this but you know how it goes.You don't find it all unless you dig it ALL
