Q&A With Detector Designer Dave Johnson
September 2011 by Chris Ralph...it’s been a little known secret that one man was involved in designing many of the most respected very low frequency (VLF) nugget detectors on the market. Dave Johnson has designed gold-oriented detectors for Tesoro, Whites, Fisher and others for more than 25 years.
The old report I read indicated all they ever did was dig some trenches and take samples. It sounded to me like a good place to take my metal detector...
As I laid in my Jeep and tried to get some rest, I began to realize how tired I was. I felt like a little kid who walked around Disneyland for 12 hours with his parents.
...more folks rolled in on Saturday morning and many were eager to venture out onto the Sleepy Bear property—all 415 acres—and try their luck at finding some gold.
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
Exposed veins and outcroppings can be a great source for gathering good gold ore for processing. Veins and outcroppings do require a lot of work to free the ore from its earthen grip, but this labor can be very rewarding.
His take of gold was pretty close to what mine was—about a quarter of an ounce. We had just gleaned about half an ounce of gold in just twenty minutes.
