Tesoro TEJON Operator's Instruction Manual

TEJÓN OPERATOR INSTRUCTION MANUAL

CONGRATULATIONS!

Your new Tesoro Tejón metal detector is part of a new series of detectors 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, or as you take pleasure in the great outdoors with
family and friends searching for precious metals. I wish we could share these experiences with
you, and all of us at Tesoro wish you the best of success.

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

The Tejón is a precision electronic instrument that will last for years if properly cared for. Treat
it right and it won’t let you down.

Good Hunting! Jack Gifford

GETTING STARTED - UNPACKING THE BOX

Your Tejón was shipped with these parts:

1 Upper Pole Assembly

Fully assembled, including upper pole stem with handle grip, padded arm bracket and control
housing.

1 Middle Pole Assembly With Pole Lock

1 ABS Lower Pole Assembly

Fully assembled, complete with two friction washers, mounting screw, and thumb nut.

1 9 x 8 Monolithic Searchcoil With 42” Cable and Scuff Cover

2 Battery Packs, Each With 4 AA Batteries

1 Operator Instruction Manual

1 Warranty Card

If any of these items are missing, contact the Tesoro Authorized Dealer where you purchased
your detector immediately.

Assembling the Tejón is simple and requires no special tools. Just install the battery packs,
mount the searchcoil on the lower pole assembly, connect the pole assemblies together, wrap the
excess cable around the pole, and plug the cable into the control housing. Finally, adjust the pole
length and searchcoil angle and you're ready!

INSTALLING THE BATTERY

The Tejón is powered by 8 AA batteries divided into 2 compartments, which are located in the
armrest housing.

Open the battery compartment under the armrest by gently grasping the bottom edge of the door
and pulling outward and upward. (The door is hinged at the top.)

Remove the batteries by pressing down on the right side of the 4-pack battery holder so that the
left side of the holder will pop up. Pull out the holder and replace the batteries as needed.

When returning the holder, note the position of the spring clips inside the armrest housing and
make sure that the battery pack contacts fit snugly against the springs. Insert the side with the
contacts first and then press down on the left edge of the battery holder to reseat the holder.

Snap compartment cover to close.

ASSEMBLING YOUR DETECTOR

1. On the lower pole assembly, remove the mounting screw and thumb nut from the pole

tip.

2. Insert the pole tip between the mounting ears of the searchcoil and align the holes of the

pole tip and washers with those of the mounting ears.
Note: The pole tip should fit very snugly into the mounting ears.

3. Insert the mounting screw through the holes in the mounting ears and pole tip—entering

from the side opposite the cable connection.

4. Install the thumb nut on the mounting screw and tighten by hand.

Note: Do not overtighten the thumb nut. It should be snug but not too difficult to
loosen up.

5. On the middle pole assembly, depress the two spring buttons and slide the middle pole

assembly into the upper pole assembly until the spring buttons click into the holes,
locking the two assemblies into place. Tighten the pole lock to secure the two assemblies
together.

6. Slide the lower pole into the middle pole until the spring buttons click into the first set of

adjustment holes. Turn pole lock to tighten the assemblies into place.

7. Wrap the cable around the pole leaving enough slack near the searchcoil to permit

searchcoil adjustment. Note: Do not allow the cable to flop loosely over the searchcoil.

Since the detector is sensitive enough to "see" the tiny wires in the cable, a floppy
cable can cause false signals as the searchcoil senses the moving wires.

8. Plug the male cable end into the female connector on the control housing and tighten the

cable thumb nut. You are finished!

Note: You will want to adjust the pole length and the searchcoil angle to your
preference.

ADJUSTING THE POLE & SEARCHCOIL

The pole length should be adjusted so that the detector does not become uncomfortable or
tiring after long periods of use. The detector grip should rest in your hand with your arm
relaxed, your elbow straight but not locked, with the pole extending out in front of you at the
approximate angle shown in the photo.

You should be able to swing the detector back and forth in front of you—using relaxed shoulder

movement—while keeping the searchcoil as close to the ground as possible. This swinging
movement is often called a “sweep.”

The searchcoil should not touch the ground during your sweep. The pole length should be
adjusted to allow this without having to lift the detector with your elbow or shoulder. The
searchcoil should rest about one inch above the ground while you are standing erect. The angle
of the searchcoil should allow the bottom to be parallel to the ground.

The pole length is adjusted by loosening the pole lock, then depressing the spring buttons and
extending or shortening the pole until the spring buttons click into the set of holes that give you
the most comfortable pole length.

To adjust the searchcoil angle, simply loosen the searchcoil thumb nut slightly and move the
searchcoil into the desired position. Tighten the searchcoil thumb nut by hand so that the
searchcoil will hold in place.

QUICKSTART - SELF-GUIDED TUTORIAL

The Quickstart is designed to teach you how to use your new Tejón. It provides a quick and easy
means of learning your detector and the concepts behind all of the functions.

You will need the following items:

1. Your fully assembled Tejón

2. AAn iron target (a small nail or screw will do), a nickel, a zinc penny (1982 or later), a

quarter, and a couple of different pulltabs

3. A nonmetal table top or counter.

Here’s what you will do:

1. Prepare for the Quickstart

2. Perform Audio Battery Test

3. Adjust THRESHOLD

4. Adjust Ground Balance for Air Test

5. Perform Air Test in All Metal Mode

6. Adjust TONE Control for All Metal Mode

7. Adjust TONE Control for Disc Mode

8. Adjust SENSITIVITY

9. Perform Air Test in Disc Mode

10. Activate TRIGGER SWITCH Mode

11. Perform Air Test in ALT DISC LEVEL Mode

12. Perform Air Test in Pinpoint Mode

Prepare for the Quickstart

Place your assembled Tejón on the nonmetal surface. Make sure that there are no metal objects
near the coil and remove any jewelry from your hands and wrists.

Start with the controls like this:

1. SENSITIVITY, DISC LEVEL and TONE turned completely counterclockwise past the

click.

2. THRESHOLD and ALT DISC LEVEL turned completely counterclockwise.

3. GROUND ADJUST turned to the 12 o’clock position.

4. TRIGGER SWITCH Mode in the center position (underneath housing).

Perform Audio Battery Test

Turn the SENSITIVITY knob clockwise just past the click to about 3 or 4. You should hear 6 to
7 quick beeps. This indicates that your batteries are fully charged and ready to go. As the
batteries drain, you will hear fewer beeps. When you only hear 1 or 2 beeps, it will be time to
replace your batteries. This test should be performed once or twice during your detecting outing.
This will ensure that your machine has the correct battery power to maintain optimum detector
performance.
