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.
