ANY Minelab would have found it as it was shallow. Funny thing, once I heard it, I just about knew it was a piece of gold. Came in at 8, and the sound was low and smooth.
Nothing fancy on the setup. Just have the highest recovery speed for a shorter signal, threshold 0, iron bias 0. sensitivity 19, Beach 1 or 2. I only have the 600 which is works just fine. Dont need all those fancy setting for the beach.
