    The engineer that developed the Tesoro Sand Shark, told us that he made this metal detector for real people, putting more control in to the users hands. What that means is, most pulse induction metal detectors made today, have the depth preset at the factory. The Tesoro pulse width knob, allows you to go as deep, 50% deeper or 50% less deep then other pulse detectors. Learn More
