Well. this news is new to me, but it seems that the writing was on the wall. I had a DeLeon and a Bandido II. Both great detectors. Tesoso' have always had great build quality. It may be just me, but the MD hobby doesn't seem as active as it was say 10 years ago. And without continued sales for Tesoro since many foreign actors have entered the field, that lifetime warranty may have started taking it's toll. Regardless, Tesoro's command a certain field of their own with the simplicity of sound and depth.
They go forever, and may be the Picaso of detectors if the hobby picks back up. To own an old Tesoro could be a premium. The "old reliable" in a future of computer glitchs.
Jack Gifford Tesoro's deserves the respect of all detectorists, just like George Payne who brought us Bounty Hunters. They were the innovators that jump started this industry.
