Had a ripper day with the sdc, its my second day at detecting with it. Found these bits of rubbish first
then another target and covered by a couple of eucalyptus leaves was this nugget
this is where it was resting, left of the coil.
it takes me a years worth of panning to match that. Then another target and this strange looking rock gave a loud sound. It's very light. I found this silver looking ball in it.
going back tomorrow to try again.
