The History of Metal Detectors, with Emphasis on Gold Prospecting

Dave Johnson, Chief Designer @ FTP & Fisher

Good evening! My name is Dave Johnson, and I’m the Chief Design Engineer for the world’s largest manufacturer of hobby type metal detectors located right here in El Paso. The brand names we manufacture include Fisher Research Lab, Bounty Hunter, Teknetics, and a number of private labels. I’ve been designing metal detectors for 27 years for several different companies, so there’s half a chance that if you swing a metal detector, I had something to do with it.

My presentation this evening is on the history of metal detectors, with an emphasis on gold machines. I’m not here to sell my company’s products, but it’d be downright discourteous of me to show up and not bring some literature and a Gold Bug 2 to demo. So after the meeting if anyone is interested I’ll be happy to talk with you.
