Very well Geo.
There is only a little problem.
Namely peep signal you get by sweeping is not from coins. I suppose that your PD only sense Earth magnetism and work as some sort of hybrid magnetometer changing sense by sweeping.
If you remove coins from the floor after beep sweeping and
left on PD the same settings then repeat sweeping without coins on floor you will get the same signal as with coins on floor.
