TIGER SHARK OPERATOR INSTRUCTION MANUAL

CONGRATULATIONS

Your new TESORO metal detector was designed to provide you with many happy hours of enjoyment in
the most rewarding hobby I can think of - treasure hunting. Ahead of you lie fascinating and exciting
experiences as you step into the past, uncovering artifacts lost by past generations. I wish we could share
these experiences with you, and we wish you the best of success.

Your Tesoro metal detector is capable of meeting your needs in a wide range of treasure hunting
situations. As with any detector, operator and familiarity is probably the limiting factor in determining
how successful you will be. We recommend that you read and understand this manual fully before
attempting to use the instrument in the field. Then, as you practice and become familiar with your
detector, your rate of success will increase dramatically.

Your TESORO metal detector is a precision electronic instrument, which will last for years if properly
cared for. Treat it right and it won't let you down.

Good Hunting! Jack Gifford

GENERAL DESCRIPTION

The Tiger Shark uses microprocessor technology to create a true dual function machine. In Normal
Mode, the Tiger Shark works like any other Tesoro detector. It uses the same great ground balance and
discrimination features that made the Bandido and Eldorado series so successful. On land, the Tiger
Shark can be used for coin and relic hunting and even gold prospecting. By using the four controls on the
outside, you can fine tune your detector to handle whatever conditions you are working in.

We all know that working in the wet salt areas is different than working in any type of dry area. This is
where the Tiger Shark outshines the land detectors. In land conditions, the most crucial adjustment is
using the ground balance to tune out mineralization. In wet salt conditions, changes in the conductivity in
the sand cause most of the problems. The Tiger Shark uses a completely different set of internal settings
in the SALT Mode than in the NORM Mode. There are no special controls or techniques to remember.
When working on a salt water beach, just switch to SALT Mode, adjust the Ground Balance and start
hunting.

The Tiger Shark continues in the tradition of other great Tesoro underwater machines by having
interchangeable coils available. Along with the 8" coil that comes standard with the detector, we also
manufacture a 7" and a 10 1/2" coil. To see if one of these coils is right for you, ask your local dealer or
check the section in this manual titled 

"Selecting the Right Searchcoil."
