new Sand Shark combines time-proven PI circuits with the latest digital
technology creating the first microprocessor controlled
PI detector for
the new Millennium. 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
interchangeable Printed Spiral coils (available in two sizes) and you
create a fantastic PI detector.
But we didn't stop there. 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
a single tone and is used for beach-combing 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.
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. All Sand Shark Search-coils are now Hardwired.
