The design of metal detectors well-suited for prospecting is an interesting process and not necessarily an easy one to achieve. It is a combination that blends the desires of what prospectors would like, the requirements of sales people and dealers, with the science and physics of what the electronics can achieve.

I had been busy representing the Prospecting and Mining Journal this spring, but prospecting season finally arrived and I’ve been out digging for nuggets—I’ve even found a few.
