Went out twice in the past few days. Day one scored the small bits, two species and one small crystal gold bit.
Day two spent the whole day finding almost nothing except a few small shotgun pellets. I was about to leave for home and was just 20 feet from the car. It was my last swing, my free hand was on its way to the Gain knob to shut down for the day and I got a really nice signal in some gravel clay mix. 4 inches down and out comes a bit of black looking rubbish. I thought it was some burnt metal as I had found this type of rubbish before. But the Iron probability read just 10% and it howled when run past the coil. I knocked it with the pick and presto, a nice 3 1/2 gram bit of gold. The black stuff turned out to be cemented black sands. And yeah, it was with the 5.3 coil again.
