VAQUERO OPERATOR INSTRUCTION MANUAL
CONGRATULATIONS!
Your new Tesoro Vaquero 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 Vaquero 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

Page 2: Installing The Battery
INSTALLING THE BATTERY Your Vaquero 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... -
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 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.

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. -
Page 6: Quickstart - Self-Guided Tutorial
QUICKSTART - SELF-GUIDED TUTORIAL The Quickstart is designed to teach you how to use your new Vaquero. It provides a quick and easy means of learning your detector and the concepts behind all of the functions. - Page 7 Adjust GROUND BALANCE for Air Test The ground balance function for your Vaquero is a form of discrimination that allows you to tune out the mineralization in the ground that may mask targets or decrease the detector’s depth and sensitivity.
- Page 8 Once you have set the correct threshold hum and adjusted the ground balance, you are ready to perform an Air Test in the ALL METAL Mode. Your Vaquero has a VCO-style ALL METAL Mode. You will find that as targets get closer to the coil, the threshold tone will get louder and higher in pitch.
- Page 9 The SENSITIVITY knob is used to raise or lower the power to the operational amplifiers, which changes the gain. Gain is a measurement of how much a signal is amplified. The higher the gain the more depth and sensitivity to small objects a detector has. Unfortunately, any small interference that is amplified can cause the detector to become erratic.
- Page 10 Super Tune Your Vaquero The Vaquero can be set up to get even better depth and sensitivity while operating in the DISCRIMINATE Mode. Super tuning is accomplished by working in the DISCRIMINATE Mode and turning the THRESHOLD knob to the highest setting.

Page 11: Operating Techniques
The audio frequency is controlled by a microprocessor and will not shift. Conclusion Congratulations, you have just finished the Quickstart for your new Vaquero detector and in the process have learned quite a lot about your detector. But experience is the best teacher. I would recommend that you get out and practice with your detector as much as possible. - Page 12 This motion is called a “sweep.” The Vaquero is 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.
- Page 13 Vaquero in the ALL METAL & DISCRIMINATE Modes. Check the area in ALL METAL Mode to be sure it's clear of trash. Then bury the targets at least 1 foot apart and from 2 to 4 inches deep to start.

Page 14: Care And Use
CARE AND USE Basic Care The Vaquero is a sturdy instrument, but it is not designed to withstand abuse. In caring for your Vaquero there are several important “DO NOTs” to remember. DO NOT use it to pry rocks loose or to beat bushes out of the way. DO NOT drop the machine into water. DO NOT use it unprotected in the rain. -
Page 15: Optional Accessories
See your Tesoro Authorized Dealer for more information and prices on optional accessories. Searchcoils The 9 x 8 monolithic searchcoil provided with the Vaquero is designed for best all-around performance. Optional searchcoils may add to your detector's performance. -

No one searchcoil is better than all the rest. Several optional interchangeable searchcoils are available for the Vaquero. They are all easy to mount and require no special tools. See the next page for a list of these searchcoils with the Tesoro part # and description. -
