Golden Sabre II OPERATOR INSTRUCTION MANUAL
CONGRATULATIONS!
Your new TESORO Metal Detector was 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. I wish we could share these experiences with you, and we wish you the
best of success.
Your TESORO Metal Detector is capable of meeting your needs in any conceivable treasure hunting situation. As with
any detector, operating skill and familiarity with this instrument are probably the limiting factors in determining how successful
you will be. We recommend that you read this manual and understand fully before attempting to use the instrument in the
field. As you become more familiar with your detector through practice, your rate of success will increase dramatically.
The TESORO Metal Detector is a precision electronic instrument, which will last for years if properly cared for. Treat it
right and it won't let you down.
GENERAL DESCRIPTION
The Golden Sabre II is high performance VLF metal detector that is capable of rejecting ground mineralization and buried
metallic trash simultaneously. It includes Notch Discrimination so that most common pull tabs can be rejected without losing
nickels and small gold rings, or so that only a particular band of desired targets will be detected. Notch Tone Target ID
provides a lone tone for targets below the Notch Level setting, and a higher tone for targets above the Notch Level setting.
Design emphasis was placed on performance and ease of use, while minimizing or eliminating those troublesome
adjustments and features that could cause a loss of performance if not used properly.
The Silent Search discriminate mode is based on motion, which means that the searchcoil must be moving slightly to
detect a target. The motion required is so slight that pinpointing is possible in this mode, however a no motion pinpoint mode
is included, which with the 8 inch open center searchcoil makes pinpointing a very simple task. The automatic ground
rejection circuitry is set to allow operation in virtually any mineralization you might encounter, although operation may be
difficult in black sand. The Golden Sabre II utilizes Tesoro's advanced High Gain Sensitivity circuitry which will provide greater
depth in particular environments plus a higher degree of sensitivity to smaller less conductive targets such as gold jewelry. An
expanded discriminator is added for greater selectivity of hard to identify targets previously detectable only when hunting in All
Metal mode. The Golden Sabre II is easily converted to hip mount operation without the need of kit or tools. Additional eight
foot length of soft braided shield cable eliminates the need of an extension cable. Tesoro's exclusive monolithically shielded
search coil compliments the technical advancements engineered into your new Golden Sabre II.
The unit is furnished with an 8" open center concentric searchcoil. We feel that this coil will provide excellent performance
in most situations. The open center greatly simplifies pinpointing.
As with any detector, the familiarity of the user with the instrument will have a great deal to do with how successful the
treasure hunter is. We recommend that you read and understand this manual fully before attempting to use the instrument in
the field.
Be sure to fill out and mail your warranty registration card to validate your warranty.
ASSEMBLY
The Golden Sabre II can be assembled in either of two configurations or easily converted from one to the other. The
electronic control housing can be mounted on the arm rest pole, or can be body mounted. Installation of the lower pole and
coil is the same for either configuration.
1. Depress the two buttons on the upper end of the lower stem, and slide it into the upper stem. Push the lower stem
up so that the buttons click into the third set of holes from the end of the upper stem.
2. Insert the pole tip between the mounting ears of the searchcoil, after removing the screw and thumb nut. Align the
holes in the pole tip and those in the mounting ears. Be sure that the rubber friction washers are in place.
It will be much easier to insert to pole tip into the searchcoil ears if you moisten the pole tip washers.
3. Insert the coil mounting screw through the coil and pole tip. Be sure the internal tooth lockwasher is on the screw
head side.
4. Install the thumb nut on the screw and tighten by hand.
Good Hunting! Jack Gifford

CONTROLS The Golden Sabre II has five controls on its front panel, and a threshold adjust on its rear panel. The front panel controls are all readily adjusted with the index finger of the hand holding the detector. 1. ON/OFF, BATTERY TEST, SENSITIVITY CONTROL. The primary function of this control is to reduce the detectors sensitivity to those influences that could make the operation more difficult for you. This control also is used to turn the power on and off. Turning the knob completely counterclockwise until it clicks disconnects the batteries from the circuit. When the knob is first turned on (clockwise), the detector will automatically test its batteries, and give you an audible indication of their connection.
- Page 3 are all readily adjusted with the index finger of the hand holding the detector. 1. ON/OFF, BATTERY TEST, SENSITIVITY CONTROL. The primary function of this control is to reduce the detectors sensitivity to those influences that could make the operation more difficult for you. This control also is used to turn the power on and off. Turning the knob completely counterclockwise until it clicks disconnects the batteries from the circuit. When the knob is first turned on (clockwise), the detector will automatically test its batteries, and give you an audible indication of their connection. NOTE: This test should be performed with the Mode Switch in the Discriminate position. Fresh batteries will cause a loud audio response which will gradually decay into silence over a period of about 4 or 5 seconds. As the batteries age and become weaker, the initial audio response will be weaker, and will decay quicker. When the response is just a short buzz instead of a long beep, or when there is no audio response, it's time for new batteries. It is recommended to always use alkaline batteries. Many things can cause the response of the detector to become erratic as you are using it. Normally you will not hear any sound from the detector unless you pass the coil over a good target. Very large targets or a multitude of closely spaced smaller rejected trash targets can cause the detector to emit choppy sputtering sounds. CB radios, radio and TV broadcasting antennas, intense mineralization changes, and other sources of electrical noise can also cause the detector to emit false signals. These signals will generally sound "chopped" and will not be repeatable so you will not have any trouble recognizing them. They can be distracting, though, and turning down the sensitivity control will help reduce them. This will also cause a small loss of target sensitivity, so always run the sensitivity control as high as you can, while still getting smooth operation. 2. SEARCH MODE SWITCH. This switch is used to select the All Metal mode of operation or the Discriminate mode. The Discriminate mode is a Silent Search ultra slow motion type, and allows a lot of user control due to its extra features like notch discrimination. The All Metal Mode is a no motion, automatic tuned, all metal mode which utilizes an internally fixed threshold sound. 3. DISCRIMINATE LEVEL. This control is used to adjust the detector's response to unwanted metallic trash when used in the Discriminate mode. At the lowest setting "0", the detector will eliminate most iron objects, but will still respond in a positive manner to light foil, bottle caps, pull tabs and most other metallic items. As the knob setting is increased, response to more of these metallic trash items is reversed so that these objects give no response. Each detector can vary somewhat, so it would be a good idea to test your detector against various targets to determine exactly where they are rejected by your detector. Do this with the notch mode switch in the OFF position. 4. NOTCH MODE SWITCH. This toggle switch is used to select the function of the notch filter in the discriminator circuitry. In the reject mode, the target encompassed by the notch will be rejected, and in the accept mode, only those targets encompassed by the notch will be detected. The notch width is factor set to be just wide enough to include the common pull tabs and lift tabs, since rejecting these objects will be its primary use. In the center position, the notch filter is disabled, so that it has no effect on the decimated circuit. 5. NOTCH LEVEL CONTROL. This control is used to adjust the notch filter response to the desired target level when using the notch discriminate modes. The notch level control should always be set higher than the discriminate level by at ...
- Page 4 determines whether a target indication is high or low tone. All Targets with phase response below the notch level setting will be represented by the lower tone 'beep', those higher than the notch level setting by a higher tone 'beep'. We recommend setting the sensitivity control at the (7) mark when beginning to search a new area in Discriminate Mode. If the detector seems to have a lot of 'chirpy' sound or false signals, turn the sensitivity control down slightly until the source of the interference is overcome and the detector will operate smoothly. Note that in very large trash areas, some clicking or chirpy sounding false signals will be caused by the heavy concentrations of metallic trash or by very large iron objects. In relatively clean areas, it may be possible to increase the sensitivity setting. When the Notch mode switch is in the off position, the amount of trash rejection is controlled by the Discriminate level Control. With the Disc level control set at about 2 or 3, the detector should reject foil and ferrous targets, while detecting those target whose phase response is higher than foil. This is shown by the solid line labeled foil reject. As the control is increased, more of the remaining targets are rejected. With the control increased to about 6 or 7, all of the targets shown are rejected except the penny and quarter. This is shown by the dotted line labeled pull tab reject. Note that at this level, the nickel and small gold ring are also rejected as bad targets. Since small gold items may have a phase response as low as foil, you can see that operating a normal discriminator at the pull tab reject level can also cause you to miss a lot of valuable finds. The Notch Filter in the Golden Sabre II can help you to overcome this inherent problem of normal discriminators. NOTCH DISCRIMINATION. In the Notch Reject Mode, the response of the detector can be more closely controlled. The Discriminate level Control is used to set the lower cutoff level, for example, to eliminate ferrous targets, foil, and steel bottle caps. The Notch Filter is then used to reject the narrow band of targets containing pull tabs. The Notch width is factor set to cover the range of most common pull tabs and lift rings would fall into, but some peculiar tabs may still be detected. If pull tabs have been chopped or mutilated by a lawnmower, the pieces may be detected as nickels, and of course, some valuable items may have the same phase response as pull tabs and be rejected. Still, the Notch Filter allows detection of nickels and small gold rings while rejecting almost all of the pull tab signals. The Notch level should always be set higher than the Disc level. NOTE: IT is possible to adjust the width of the Notch Filter, but we recommend for best result to leave it set as it comes from the factory. If it becomes necessary to readjust the Notch Width to suit particular circumstances, contact your dealer for details. The Notch Accept Mode allows the detector to respond only to a narrow band of targets. This may be useful if you are searching for a particular target, such as a lost ring or treasure hunt token. It is also useful to help you classify or identify a target before digging. Each detector can vary somewhat due to manufacturing tolerance, so you should experiment with your detector and become familiar with the rejection levels for these trash items with your detector. Earlier motion detectors that operated with "threshold" sound would give the user a definite indication of metallic trash by either nulling completely or by generating short, choppy sounds. Since the Golden Sabre II operates without threshold sound, there is no nulling to indicate that the area is extremely trashy, but under such circumstances the detector will probably also emit some short chirpy sounds. These are easy to distinguish from the good target's longer cleaner sound. Since the notch filter response is like a "window" the notch level must be centered on the desired targets, rather than just set higher than the target. The preset mark at the '6' on the notch level is an ideal starting point to provide pull tab rejection while still finding nickels. It will probably be necessary to make some small correction up or down to accurately center the notch response on the pull tab range. When set correctly, the notch level is set to be just wide enough to eliminate most common tabs. The aluminum screw cap is so close to the response of coins, that we feel it's best to not include it in the notch. The targets in the shaded area ...
- Page 5 In areas with well kept lawns, the easiest way to maintain a constant searchcoil height is to allow the coil to rest on the grass as you sweep from side to side. In rough and rocky areas it is best not to “scrub” the coil on the ground, as the rocks will act like abrasives, and wear away the coil bottom (an optional coil scuff cover will protect against this.) Sweep the coil as close to the ground as possible without touching. Hitting the ground or rocks may cause a false signal much like a desired target would. Sweeping the coil too high above the ground results in a loss of depth. When operating in the Discriminate Mode, some “false signals” may be caused by heavy concentrations of trash metal objects, by very large trash items, or by electrical interference. These signals will sound different than good target signals because they are generally short, choppy sounds. At the end of your sweep, as you the reverse the coil direction, the detector is most susceptible to trash induced noise. There are two ways to tell whether these sounds are good deep signals or trash “noise.” The first is by repeatability. Trash induced noises will not be regular as you sweep the coil over the suspected target several times, whereas a good target response will be repeatable. The second method is to switch to All Metal Mode and check the target response sound. If the response is weak, it may well be a deep, good target; but if the response is very strong, it is probably trash. Note that a coin close to the surface can give a double beep sound, but it is regular and repeatable. Raising the coil an inch or two will restore the single beep on surface targets. Raising the coil an inch or two will also many times cause surface trash false signals to suddenly disappear, while good target responses just become fainter. If the trash in an area is so heavy that you are getting lots of choppy sounding false signals, it might be good to change to a smaller coil. If this isn't feasible, you can probably get better results by slowing down your sweep speed, and using shorter sweeps. It would be good to hunt the area twice, the second time at right angles to the first time. This technique will probably allow detection of some targets that were hidden by trash the first time due to the sweep direction. If there is any doubt whether a target is good or not, DIG IT. If you don't dig any junk at all, you are surely passing up a lot of good finds, too. Set the DISC LEVEL only high enough to suit the conditions where you are searching, and use the Notch Filter if called for. The detector is furnished with an 8" concentric searchcoil with an open center. This coil will yield the best results for most coin hunting situations. Pinpointing is greatly simplified by an open center, since you can now see the actual point on the ground where you will dig instead of logging your eyes on the coil center and trying to to follow the coil as you move it out of the way. Optional coils of 4", 7" and 11" are available to allow you to tailor the response of your detector to suit special situations. The 4" and 7" coils are useful for coinshooting in extremely trashy locations and can actually greatly increase your number of good finds under such conditions, although some loss of depth will be experienced. The smaller coil will allow you to detect coins and other good targets much closer to surface trash items. The 11" coil will yield about an extra inch in depth in most areas. The increased surface area makes pinpointing a little more difficult, and allows trash to hide the good targets a little easier. The 11" coil is also an excellent relic hunting coil and can provide greatly increased depth on larger targets, especially in the All Metal mode where surface junk won't hide the deep targets. Because most detector users are coinshooters and most areas are likely to yield good coins are also likely to contain a goodly amount of trash, the Golden Sabre II is furnished with an 8" searchcoil as standard. This coil will probably yield the best results in most such situations, and is easier to pinpoint with than the larger coils. Optional searchcoils of 4" through 11" are available to allow you to tailor the response of your detector to suit other conditions. The 4" coil is useful for coinshooting in extremely trashy locations, and can actually greatly increase your number of good ...
- Page 6 TESORO Metal Detectors are sold through independent dealers, who are almost always treasure hunters themselves. They can provide you with you much needed information about how to use your detector, how to probe, plug and dig in your locale, and answer most of your questions about treasure hunting in general. The use of earphones will benefit you in two ways. Most earphones will very effectively block out most of the ambient noise, such as traffic noise and wind noise, which will enable you to better hear the fainter signals caused by the deeper targets. Obviously, the older, more valuable coins will probably be deeper than the ones which were lost last week, so you should take advantage of anything that will help you hear the weaker signals. Secondly, using earphones will greatly extend the battery life, since it takes much less power to operate them. The Golden Sabre II is not equipped with a volume control, but does have a limiting circuit in the earphone jack. If less volume is desired with earphones, you may want to use earphones with a built in volume control. Any good 8 or 16 ohm set with 1/4 inch stereo jack will do.
