TESORO DETECTORS
Tesoro Cortes represents the best combination of current and new technologies that Tesoro has to offer. When Jack Gifford and Vince Gifford set out to create a new target ID machine they each brought with them different experience. Jack has over twenty-five years experience designing some of the best analog detectors that have been on the market. Vince brought with him a decade of computer systems experience. Together, they have been creating new technology that gives our detectors superior performance and keeps them easy to use. Various parts of this technology have been finding it's way into Tesoro detectors since the introduction of the Golden µMax. The new Cortes represents all phases of our new microprocessor technology combined with our tried and true analog circuits to create a detector that has all of the high end features our customers have asked for with user friendly Tesoro controls. The first thing that you will notice is the control box and battery holder configuration. The µMax housing was just not big enough to hold the new circuit board so we moved the batteries down under the arm bracket and increased the size of the box slightly. This allows us to use a 12 volt system to work with the demands of the target ID circuitry. It also gave us the ability to put a 2¼" speaker on the Cortes. This will give better and louder target signals in the field.
The Cortes' 2x16 character LCD display will catch your eye as well. This area is the information center of the detector. The top row is an alpha/numeric display that gives a broad indication of your possible target. One of five different categories are displayed. Also if the target is overdriving the circuits, the display will tell you to lift the coil for a more accurate reading. The alpha/numeric and bar graph section of the display will remain blank until the coil passes over a target. After the detectorist has decided to dig or ignore the target the display will clear itself after six seconds of not receiving a signal. The display works in all modes, regardless of the discrimination setting. By clearing the display after six seconds the user is able to tell if has passed over a new target that may have been discriminated out. The detector may not produce an audio signal, but the display will show a target reading. The detectorist then has the choice to either go back and check the target or ignore it.
The bottom half of the display contains the real nuts and bolts information that will help you to work the Cortes to its fullest extent. The far right hand part of the display is a battery level indicator. This gives an accurate measure of your current battery level. On the far left-hand side is the probable depth indicator. The Cortes uses the phase shift of the target to determine the probable target and then looks at the amplitude of the signal to determine the depth. For example: a nickel and a quarter are in the ground and the quarter is deeper than the nickel; if we just went off of amplitude change, the detector may read the two targets as being the same depth. However, the Cortes would show the quarter as being deeper because its phase shift response is different than that of the nickel.
In the center of the lower display is a nine segment bar graph display. The different segments represent the following possible targets: iron; foil: nickel; round tab; square tab; zinc penny; copper penny and dime; quarter; half and dollar. The graph shows what the coil saw during the entire sweep of the coil. The targets metal composition and orientation in the ground can cause "smearing" or possible indication in more than one graph segment. For example: pull tabs usually will not respond in a single segment but give signals in two or three segments. To help the detectorist decide on the target, we have also included an ID Number display next to the bar graph.
The ID Number takes the largest part of the signal and converts it to a two digit number. When Vince put together the scale for the ID Number, he decided to put the most resolution in the middle range of targets. This is the area where nickels, pull tabs and gold rings lie. We know that iron will always be on the low end of the scale and silver coins and jewelry will always be on the high end. So iron targets will always give a reading of 0 and silver will always give a reading of 95. The Cortes now gives you the ability to decide what you want to dig. One of the hardest parts of designing detectors is the fact that pull tabs can vary from place to place. But a hunter working in the same area can use the ID Number to learn the characteristics of the local pull tabs and effectively ignore them.
For those detectorists that prefer a notch filter discrimination, we have also added a simple flip switch to activate either a narrow or wide notch window. When the display is blanked, two "N"s or three "W"s will appear on the screen. The N will indicate a narrow notch window and will be in the round tab and square tab portion of the graph segments. The wide notch window will cause a W to be in the round tab, square tab and zinc penny segments. These indications are an easy way to check what part of the scale is being notched out. The notch indicators will only show when there is no target under the coil. When there is a target signal, no matter if the target has been discriminated or not, the display will show the information of the target.
The Sum mode is another feature to help identify targets. While the detector is in either the Discriminate or All Metal mode, the display shows the target information from the entire sweep of the coil. Each time the coil passes over the target the microprocessor generates a new target ID reading. While this is nice for general searching, it can be confusing while pinpointing. This is where the Sum mode becomes useful. Pushing the spring-loaded switch into the Sum mode causes the detector to start a multi-tone ID and averages all of the coil passes over the target. The tone ID has nine different tones and relates directly to the bar graph segments. The higher up on the graph the target is, the higher the pitch of the audio signal. Averaging the coil passes over the target gives the detectorist the ability to get rid of most of the signal noise that prevents making an accurate target identification. Here's how it works: when the detectorist gets a target signal that he wishes to check out, he pushes and holds the Mode switch in the Sum position. Shortening his coil sweep to only a two or four inch sweep he passes the coil over the target three to seven times. The short multiple sweeps give the microprocessor the chance to sum the passes and average them. During the sweeps the audio ID will start at the lowest signal and will get progressively higher in pitch until there is no more change. When this happens the detector is giving the most accurate ID possible. Then the user can decide if he wants to dig or ignore the target.
All of these new features are complimented by Tesoro's easy to use controls. No touch pads or scroll through menus. Set the detector how you like it by adjusting the knobs on the front of the machine. The Cortés features an On/Off Sensitivity knob; A Discriminate Level knob; A Manual Ground Balance knob; A Mode Switch with All Metal, Discriminate and Sum mode settings; A Notch Width switch with Off, Narrow and Wide settings and a Light switch to control the LCD back-light with a High, Low, and Off positions.
The Cortes fits into a package that weighs just less than three pounds (including the batteries!) and is covered under Tesoro's Lifetime Warranty. The Tesoro Cortes makes target ID easy and fun. Contact your local dealer or the factory for more information.

Tesoro Deleon is a Target Identification Metal Detector or T.I.D. The DeLeon is designed as an easy to use, turn-on-and-go metal detector. The faceplate has only four controls: Sensitivity, Discriminate, Threshold and a Mode Switch. It uses the same circuitry as the Cortes, so you can expect the same depth and sensitivity from the DeLeon that the Cortes metal detector is well known for.
The DeLeon's display screen is one character high by eight characters wide. It is larger and easier to read than the Cortss display but does not carry as much information. Starting from left to right on the faceplate, you will see that the DeLeon has a Coin Depth reading, a five segment bar graph and a two-digit Target ID Number. The bar graph shows several categories for ID purposes, but we recommend that it be used with the ID Number for the most accurate information.

During the design phase of the Tesoro Vaquero (pronounced va-care-oh), we knew that it was going to be a very hard working metal detector. It is designed as an all-around metal detector, able to do just about everything that any detectorist could want to do. Vaquero is the Spanish word for cowboy. When we think of hard work and the ability to take on any kind of tough job, we think of the cowboys of the old west.
The main part of the Vaquero’s versatility is its three and three-quarters manually adjusted ground balance. This will give the detectorist the power to set up his machine to best suit the mineralization conditions that he is working in and his personal treasure hunting style. The Tesoro Vaquero adds an ED180 discrimination feature to filter the trash from the treasure and a Push Button Pinpoint that makes digging up the goodies that much easier. The discriminate knob is also used to switch into a threshold-based All Metal Mode.

It’s Tejon Time
Tesoro Tejon metal detector features a high output transmit oscillator to push the signal deeper and an increased gain for sensitivity to smaller items. The Tesoro Tejon metal detector was designed from the ground up with the coin and relic hunter in mind. It also features a new color scheme from Tesoro- blue, gray and black. The Tejon was over a year and a half in the design stages and represents a new generation of Tesoro detectors.
Once you get past the new color scheme, the first thing that you will notice is the lack of a mode switch on the faceplate. We have moved it beneath the control housing so that you are able to switch modes quickly. Pinpointing and checking your targets with the Alternate Discrimination is a breeze.
The Tejon’s two discriminate modes are fully user definable. The engineers at Tesoro have given the user the ability to set the machine for their hunting needs. Each discriminate mode uses ED180 circuitry. The regular discriminate also incorporates a full-time all metal setting. Want to hunt in all metal and check the targets for iron or discriminate out iron and perform a check for high value silver or gold targets? It’s no problem for the Tejon. Simply set the Discriminate and Alternate Discriminate modes for your style of hunting and swing the coil. Then use the Trigger Switch to quickly change modes to check your targets. Push the trigger forward to activate the Alternate Discriminate or pull the trigger back to pinpoint the target. The Tejon makes it fast and easy.
But the user definable features do not stop there. The Tejon has a manually adjustable ground balance that works for both the All Metal mode and both Discriminate modes. Using a three and three quarter potentiometer, the Tejon will meet and defeat all soil conditions and is suitable for any hunting style.
The Tejon also has an audio tone adjust. If you have trouble hearing certain tones or have certain tones that you are more comfortable with, the Tejon can meet you desires. Using the tone adjustment control, you can switch from a normal tone with VCO pinpoint all metal to any one of thousands of different audio tones for the All Metal and Discriminate modes. Fine tune the tone until it is right for you and see how much easier it is to find, pinpoint and dig the targets that you are looking for.
While the Tesoro Tejon was designed mostly for coin and relic hunters, its user definable controls are simple and easy to use making it able to handle just about any type of treasure hunting that you may wish to try.

Tesoro 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 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.
Tesoro Tiger Shark Metal Detector Features:

- 12 kHz Frequency
- 8" Waterproof Search Coil (Optional Coils Available)
- Normal and Salt Operating Modes
- Built-In Headphones
- Eight AA Alkaline Batteries, Drop-In Compartment (10-20 Hours Typical)
- Waterproof to 200 ft.
- Interchangeable Search Coils
- Lifetime Warranty

Tesoro 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 Electronics' exclusive interchangeable Printed Spiral coils (available in four 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 with 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-III battery compartment for quick and easy changes. The Tesoro Sand Shark will change the way that you think about pulse detectors.

FEATURES:
- 600 pps Operating Frequency
- 8" Search-coil, Printed Spiral
- 220-450 Hz Audio Frequency
- Stereo Headphones
- Weighs Less Than 4-1/2 lbs.
- Eight AA Alkaline Batteries, Drop-in Compartment, 10-20 hours typical
