Ive been a bit out if touch with detecting these last years. Could someone tell me what happened to Tesoro? Ive had most of their machines, made alot of great finds with them. Does anyone do repairs on them now in case I was to pick one up again?
Thank you,
Neil
Well if memory serves me right, I will try to summarize a little history here. Jack Gifford was the founding member with his wife, Myrna; this was 1980. But before Tesoro Electronics, Jack received his Bachelors in electronics engineering. He went to work for Bounty Hunter metal detectors as an EE. That was in the early '70's.
Jack left them and his wife moved to Prescott AZ and decided to start their business. Most electronic circuitry at that time was big, bulky and heavy. And most chassis were made of metal and heavy too. Of course Tesoro was in the same boat with White's, Garrett's and Minelab, etc. Jack envision a smaller, light weight design. This in due part with new micro circuitry or surface mounted boards that were being brought into the market.
Jack's new design for a smaller package was called micro-max. Their design was lighter in weight, more ergonomic to the user and less fatigue for all day hunting. The micro-max or umax is powered by a 9-volt transistor battery. Alot of critics heads were turning in the MD field. Some these folks were saying that "This detector won't find anything... too small". "It's made for little kids". "Under powered with just a 9 volt battery". Jack proved the critics wrong! Testing here in the U.S. and abroad proved significant finds.
Fast forward. Jack passed away and the company was taken over by Myrna and his 2 sons, James and Vince. They were successful for quite a number of years. In the mid 2000's, James had some health issues and couldn't give 100 percent anymore to the company. Correct me if I'm wrong, but I believe they shut the doors in 2007 or 2008???
Great detector by a great designer, Jack Gifford!! I've owned in the past, Sidewinder, Bandido II, Vaqureo, Eldorado and
