The Tesoro Golden uMax metal detector has undergone a new and improved tone change! By changing the pitches, Tesoro has made it easier to distinguish all 4 tones clearly, which makes it easier to identify targets. Starting with the serial number 190900 (the manual has Rev 2.0 on the cover) in April 2011, all detectors have these new and improved tones. The lower tones better identify potential trash and higher tones reflect valuable targets such as silver and nickel.
Please note the correct way to set up a Tesoro Golden uMax metal detector
: the notch-width control MUST be adjusted while air testing nickel with the discriminate control turned completely down to "min." With the notch switch in either wide or narrow position, adjust the notch-width to obtain a good target sound on nickel. This will give you 4 target tones. If the notch-width is NOT set correctly, you will hear only 3 tones.
If you already own a Golden uMax metal detector and want to have the tones changed for $50, please contact Tesoro directly.
Tesoro means treasure, and that's exactly what you'll find with the Golden uMax Metal Detector
