Tesoro Golden µMax Operator's Instruction Manual

GOLDEN µMax OPERATOR INSTRUCTION MANUAL

CONGRATULATIONS!

Your new Tesoro Golden µMax 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 Golden µMax 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

GENERAL DESCRIPTION

The Golden µMax is designed to help detectorists improve their coin shooting finds. It
combines three systems to help identify targets before they are dug. First is Tesoro's tried and
tested ED120 discrimination. Offering 120° of discrimination range covering a broad
spectrum of unwanted targets. Second is a four tone audio ID. The tones cover 1) iron and
foil, 2) rings, nickels and some pull tabs, 3) most pull tabs and screw caps, 4) pennies, silver
coins and jewelry. A special tone for targets that are causing the machine to saturate is also
included. Third is a Notch Filter discriminate. Notch discriminate will allow you to tune your
Golden µMax to discriminate out most pull tabs while keeping the nickel and gold ring. It is
user adjustable to fit the hunting styles of most detectorists.

The Golden µMax uses a state-of-the-art microprocessor to perform all of these functions and

still keep a weight of less than 2˝ pounds. With a standard 9x8 coil and three piece break

down pole, the Golden µMax is sure to help you meet your detecting goals.

GETTING STAR TED - UNPACKING THE BOX

Your Golden µMax 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 Lower Pole Assembly

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

1 9 x 8 Concentric Searchcoil With 3’ Cable

1 9 Volt Alkaline Battery

1 Operator Instruction Manual

1 Tesoro Warranty Card

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

Assembly of the Golden µMax is simple and requires no special tools. Just install the battery,
mount the searchcoil on the lower pole assembly, connect the two 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 TH E BATTERY

Your Golden µMax is equipped with a battery test switch so that you can always be sure you
are getting top performance. (See QUICKSTART for operation.) The battery should be
checked after the detector has been on for about 10 minutes and then periodically when used
for long durations.

To install or replace the battery, first make sure the SENSITIVITY control is set to POWER
OFF—turned completely counterclockwise past the “click.” Remove the battery door from
the back of the control housing. Do this by pressing your thumb firmly on the louvered
square—at the bottom of the battery door—and sliding the battery door upward in the
direction of the arrow.

Check the polarity on the battery and on the diagram inside the battery compartment. Make
sure that they match and simply drop a fresh 9 volt alkaline battery into the compartment.
Note: If the battery is not installed properly, damage may occur to your detector.

Replace the battery door by sliding it into place making sure the upper mount slots are in line
and the lock tongue is snapped in place.

(Above photo depicts the Silver Sabre µMax model; however, battery installation is the
same for the Golden µMax.)

ASSEMBLING YOU R DETECTOR

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

black nylon 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,
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 spring buttons click into the first set of

adjustment holes. Turn pole lock to tighten, thus locking the assembly 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.

(Above photos are shown using the Bandido II µMax
model; however, assembly procedures are the same for the
Golden µMax.)

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, and 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 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

The Quickstart is designed to teach you how to use your new Golden µMax. 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 Golden µMax.

2. An iron target (a small nail or screw will do), a nickel, a quarter and a couple of

different pull tabs.

3. A nonmetal table top or counter.

Here’s what you will do:

1. Perform Audio Battery Test

2. Adjust Threshold

3. Perform Air Test in ALL METAL Mode

4. Adjust the SENSITIVITY

5. Check and Identify Discrim i nat e ID Tones

6. Perform Air Test in DISC Mode

7. Set Notch Window Width

Prepare for the Quic kstart

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