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. Add Tesoro Electronics' exclusive interchangeable Printed Spiral coils (available in two sizes) and you create a fantastic PI detector!
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.
Tesoro added a microprocessor to help you customize the detector to your specific needs. The 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. The Sand Shark also has a new drop-in battery compartment for quick and easy changes.
The Tesoro Sand Shark will change the way that you think about pulse detectors!
The Sand Shark Searchcoils are now hardwired. The two coils that come stock are the 8" and the 10.5 -- choose coil size when ordering. Smaller coils tend to work better in trashy areas, have better sensitivity toward smaller pieces of jewelry, such as chains, and are lighter weight. The larger coil will go deeper on quarter size or larger objects in most conditions.
