Challenge Coins (Tungsten)
Tungsten & Gold are virtually identical in weight! So here are some test tokens to evaluate your system, does it measure up to even the simplest of gold capture?
- 4x 6mm X 1mm (.236 dia. will go thru 1/4" screen)
- 4x 8mm X 1mm (.314 dia. will go thru 3/8" screen)
- 2x 12mm X 1.5mm (.472 dia. will go thru 1/2" screen)
- 2x 16mm X 1.5mm (.629 dia. will go thru 3/4" screen)
Mix these with your material & run till you clean up. See if your system catches them all.
Don't put them in 1st or last, that's cheating. If you're dredging suck a few up after you've been at it for 30 mins or so.
Why would we do such a thing? Cause "seeing is believing" or as folks may say "prove it!"
