Well, actually just another tool.
I found a lead looking object one day, threw it in my pouch with all my coins.
When I got home, my coins were clumped together.
So I had thought, after some one told me his friend magnetizes his digger tool.
So I took the lead object which was a magnet and epoxied it into a wood chisel handle.
This handy tool only works in Canada, where modern day clad coins are made of nickel plated steel.
Now it doesn't beep or buzz or light up but, it does make a loud snap sound when the coin hits the magnet. The magnet will pull coins from loose soil.....
