Product Code: MD-TIGE-BA/8RC-LW-HW

Availability:Out of stock

Tesoro Tiger Shark Metal Detector with 8" Search Coil, Headphones, Pole Assembly With Pole Lock, Batteries.
The Tiger Shark is a true dual mode water machine using microprocessor technology. It has a Salt Mode to be used only for wet salt sand or salt water hunting and a Normal Mode for fresh water or dry land hunting. 

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 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.

Working in the wet salt areas 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.

The Tiger Shark Searchcoils are now Hardwired.

Tesoro Tiger Shark Field Test

By Gene Scullion

The Tiger Shark is the newest addition to the Tesoro line of water detectors, replacing the popular Stingray series of machines. Its arrival has been anxiously awaited.

I have been using Tesoro machines since 1984, and over the years, I have used many different models. It did not take long at all for me to be impressed by their silent search operation and their great discrimination. Over time, I came to respect the great quality of their machines and their great service department.

When I bought my first Tesoro water machine in January 1997, I had been using another well-known brand for over six years. I decided to go with a Tesoro water machine because I was tired of digging hundreds of nails every week, and I really liked the idea of having interchangeable searchcoils. The fact that they also had a reputation for being good at finding small gold rings and chains was simply an added "plus." In 6 years with my previous water machine, I never found a single gold chain. In my first year with the Tesoro, I found 3-and one was 24K!


The Tiger Shark is a true dual mode water machine using microprocessor technology. It has a Salt Mode to be used only for wet salt sand or salt water hunting and a Normal Mode for fresh water or dry land hunting. The two different modes use completely different internal settings and cannot be interchanged. On dry land, it can be used for coin, relic, or even gold prospecting.

The Tiger Shark pole assembly breaks down into three pieces for ease of storage and travelling. It is the popular S-style pole design with a padded handle grip and arm bracket, and it has an adjustable Velcro arm loop. All three pieces fit together with interlocking spring buttons and the top two sections each have a locking-bushing that eliminates any chance of pole wobble. To convert the pole assembly to a diver version, you simply remove the center pole section.

The Tiger Shark can be assembled in several different configurations. The control housing can be mounted to the pole assembly in two different locations or worn on a belt utilizing the built-in slots. It can be clipped to the pole assembly directly under the arm or directly in front of the hand grip area where the controls can be easily adjusted while hunting. The pole assembly has spring buttons in both locations for easy attachment and removal of the control housing.
