    Minelab GPX5000 - So much more to learn

    Shallow ground observation

    Shallow gold

    Goldierocks, from what I'm experiencing from this 1 gully, @ approx 2m down there is a layer of gravels approx 0.5m thick, there is SOME gold in it but from deeper digging the ground is turning white/orange clay. What's deeper?
