Tesoro Sand Shark

The Tesoro Sand Shark combines digital microprocessor and pulse induction technology to deliver outstanding underwater performance. PI metal detectors like the Sand Shark are immune to the nasty effects of ground mineralization making it effective in any type of ground condition on land or water.

A control knob for Pulse Width allows the user to quickly adjust the machine’s depth and sensitivity. As pulse width is increased more battery power is consumed, but Tesoro’s designers have balanced sensitivity and battery use at its middle setting. Audio preferences are also easily controlled via the Threshold and  Volume knobs.

Separate search modes also make it relatively easy to use. Detectorists can simply choose Normal mode, and then select their desired target ID frequency and start hunting. Meanwhile, using the Sand Shark’s VCO audio feature can easily pinpoint target locations as the audio tone’s pitch gets higher and louder around a specific target area.

An 8 inch printed spiral search coil while accessory coils ranging from 7, 10 and 10.5 inch are also compatible with the Sand Shark. It can also be hip mounted making it convenient to use while diving for sunken treasure. The waterproof control box and search coil are rated for up 200 foot depths.
