"The Name That Means Treasure"

CONGRATULATIONS!
Your new Tesoro DeLeón 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, familiar-
ity 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 DeLeón 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

Assembling the DeLeón is simple and requires no special tools. Just

bly, 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 DeLeón is powered by 8 AA batteries divided into 2 compart-
ments, 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 snug-
ly 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.
GETTING STARTED 4

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 dif-
ficult to loosen.
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 but-
tons click into the holes, thus locking the two assemblies into place.
Tighten the pole lock to secure the two assemblies together.

6) Slide lower pole into middle pole until the spring buttons click into
the first set of adjustment holes. Turn pole lock to tighten the assembly
into place.
7) Wrap the cable around the pole leaving enough slack near the search-
coil 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.
Note: We have included an optional Velcro arm strap with your DeLeón
detector. To install, remove the backing on the two smaller hook patch-
es and press firmly to sides of arm cup. Adjust strap to provide snug
comfortable fit.
GETTING STARTED 6

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 approx-
imate 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 with-
out 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 search-
coil should allow the bottom to
be parallel to the ground.
The pole length is adjusted
by loosening the pole lock,
then depressing the spring but-
tons 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.

GETTING STARTED 8
The Quickstart is designed to teach you how to use your new
DeLeón. It provides a quick and easy means of learning your detector and
the concepts behind all the functions.
You will need the following items:
1) Your fully assembled DeLeón.
2) An Iron target (a small nail or screw will do), an iron wash-
er, a nickel, a zinc penny (1982 or later), a quarter and a cou-
ple of different pull tabs.
3) A nonmetal table top or counter.
Here's what you will do:
1) Check Display Readings in DISC Mode
2) Adjust SENSITIVITY
3) Perform Air Test in DISC Mode
4) Adjust THRESHOLD
5) Perform Air Test in ALL METAL Mode
6) Perform BATT TEST
Prepare for the Quickstart
Place your assembled DeLeón on the nonmetal surface. Make sure
that there are no metal objects near the coil and remove any jewelry from
your hands and wrists.

9 DELEÓN OPERATOR INSTRUCTION MANUAL
Start with the controls as shown in the photo below:
1) THRESHOLD, SENSITIVITY and DISCRIMINATE LEV-
EL knobs turned completely counterclockwise.
2) MODE switch in the DISC setting.
Check Display Readings in DISC Mode
Turn the SENSITIVITY knob from OFF to about 2-3. In the first
couple of seconds, you may or may not hear a slight hum that will fade
away and the display will read TESORO, DELEON and DISC. As long
as these three screens show up, you can be assured that your DeLeón has
started up properly.
