This detector consists of two crystals--copper pyrites (Cu Fe S2) and zincite (zinc oxide ZnO), held in firm contact against each other in the manner shown. The copper pyrite crystal is mounted in a cup mounted on a spring-actuated rod provided with a suitable knob, by which it can be swung in any direction. Zincite crystals are mounted in a large cup containing..."

It works, you need to rotate the crystal around to find a good contact, and it's a bit easier than fiddling with a cat's whisker in some ways. I managed to get some good results in testing but it does have a couple of drawbacks. Firstly it's pretty dangerous! Seco..."
