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.

Page 2: Installing The 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. -
Page 3: Assembling Your Detector
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. - Page 4 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.

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.”... - Page 6 Start with the controls like this: 1. THRESHOLD, SENSITIVITY and DISCRIMINATE LEVEL knobs turned completely counterclockwise. 2. MODE and NOTCH switches in the center position. 3. NOTCH WIDTH knob at the 12 o’clock position. Perform Audio Battery Test Turn the SENSITIVITY knob from OFF to about 7 or 8. You may hear a brief beep. This is just the detector turning on and does not signify anything.
- Page 7 Adjust the SENSITIVITY We are now ready to switch the detector into the Discriminate MODE. Go to the mode switch and flip it all the way to the right and into the DISC position. The first thing that you will notice is that the threshold hum stops.
- Page 8 with target ID features, this can cause some problems. We have created a very specific double beep signal that lets you know when a target is very close to the coil. Start with any of your targets and start waving it about 4 inches away from the coil. Slowly move the target towards the coil until you hear the double beep.
- Page 9 We are now ready to discriminate targets from each other. We will start with the DISCRIMINATE LEVEL at MIN. Please notice that the DISCRIMINATE LEVEL knob has words that correspond to the items that are discriminated out. There is also an arrow between Iron and 5˘.

Page 10: Operating Techniques - Field Use
NOTE: No detector can guarantee to discriminate out all of the pull tabs and respond to all of the gold rings. The Golden µMax uses the Notch Width knob so the user can determine the amount of Notch Filter Discrimination that is right for their location and hunting style. With the DISCRIMINATE LEVEL at MIN, move the NOTCH switch to the left into the NARROW position. - Page 11 side to side in about a three foot arc, overlapping succeeding strokes well. This motion is called a “sweep.” The Golden µMax was designed to get maximum depth without the frantic pace required of earlier motion detectors, so go at a pace that is comfortable for you. In fact, trying to hunt too fast may even cause a loss of depth in heavily mineralized locations.

Be sure to fill all holes after you recover the target. Be sure to protect your hobby by leaving the site cleaner than you found it and with all holes filled!
