Tesoro Sand Shark Metal Detector with 8 inch Hardwired coil

Pulse Induction (PI) detectors have always been the natural choice for working wet salt beaches. Their circuitry and single loop coils will not see changes in salt-water conductivity that drive a VLF-style detector crazy. The Sand Shark has two distinct operating modes: VCO and Normal. When working in the VCO mode, as targets get closer to the coil, the threshold generates a louder, higher pitched tone great for pinpointing. The Normal mode works with a single tone and is used for beachcombing and other prolonged searches. We've added a microprocessor to help you customize the detector to your specific needs. Our Pulse Width control allows you to tune your detector to the best balance of depth, sensitivity, and battery life. You can also change the Normal mode audio frequency. Simply use the "F" Adjust knob to set the tone and you're ready to go.

JR's Review. This Pulse Induction Tesoro metal detector does a great job underwater and on fresh or saltwater beaches, but what really makes it special is the fact that Tesoro gives you a lifetime warranty on this metal detector!
