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.

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.
5.
Wind the searchcoil cable around the pole.
6.
Leave enough slack in the cable at the searchcoil to allow adjustment of the coil's angel.
CAUTION: Too much slack may permit the cable to flap across the searchcoil while in use causing false signals.
POLE MOUNT
1.
The control housing is already mounted on the pole, as shipped from the factory, so all that is necessary is to insert
the searchcoil connector into the control housing connector, and tighten finger tight.
2.
Use the two velcro straps to hold the cable tight against the pole.
NOTE:
The cable will last much longer in the body mount configuration if some care is taken to spread the necessary
flexing over a large area, rather than making a sharp bend away from the pole at cable clip which would concentrate the
flexing in a small area.
BODY MOUNT
1.
To use the detector as a body mount, simply remove the control housing from the upper pole by depressing the
spring nuts in the plastic mounting piece, and slide the control housing off the pole.
2.
Insert the searchcoil connector into the control housing connector and then finger tighten.
3.
Use the two velcro straps to clamp the searchcoil cable. It will be best for you to sometimes move the straps so that
the wear on the cable is spread over a large area.
CONVERSION
Obviously, converting the unit from body to pole mount or vice versa, is simply putting the control housing back on the
pole, or removing it from the pole. Be sure to keep the searchcoil cable wound tight enough around the pole that it doesn't flap
right over searchcoil housing. The Golden Sabre II is strong enough to see the tiny cable wires moving, and can give you false
signals if the cable is too loose.
The arm rest on the rear of the handle can be moved forward by removing the screws and nuts, and reinstalling the
assembly into the most forward set of holes.

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.
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
least one full increment for proper operation. This control also can serve as a tone control if the notch filter is not used,
since all targets below the notch level are indicated by a lower audio tone than those above the notch setting. Setting the
control at '0' will provide the higher audio tone for all targets detected in the Discriminate mode while setting it at
maximum would provide the lower audio tone.
6.
THESHOLD CONTROL.
This control is placed on the back panel of the detector, since it requires very little usage.
Once the control is adjusted to the desired threshold, it will not require frequent resetting. Turn control clockwise or
counterclockwise to a setting whereby the tone is barely audible.
TUNING
Since the most troublesome adjustments of standard detectors have been automated in the Golden Sabre II, the tuning
procedure for this detector is simply a matter of selecting the desired operating mode, setting the sensitivity level, and the
discriminate level. If you select the discriminate mode, you should begin operation with the sensitivity control set at about 7.
In most situations you are likely to encounter, you will be bale to operate at this setting. If there are sources of electrical
interference present, or if the area is extremely trashy or mineralized, your detector may give some false signals. These
signals are generally short choppy sounds which can easily be distinguished from a good target response. Turning down the
Sensitivity control will help to eliminate most of these signals, if necessary. It may also be possible in some areas to increase
the sensitivity setting.
SELECTING THE PROPER MODE OF OPERATION
The Golden Sabre II offers two basic operating modes, Pinpoint All metal or Discriminate. The Discriminate mode also
has the further capability of using notch discrimination.
A.
ALL METAL MODE.
This mode is useful for relic, cache, or nugget hunting. The ground rejection is internally preset
so that normal soil mineralization is slightly positive. This means the threshold sound will increase somewhat as the
searchcoil is lowered to the ground. The automatic tuning should keep the detector tuned to threshold as you are using it,
but by momentarily punching the mode switch to the fast tune position, the detector can instantly be brought to
threshold. All other features of the detector, such as notch tone target ID #, and notch filter, are not operative when the
unit is in the All Metal Mode. The audio sound is always the lower of the two notch tones when in the All Metal Mode.
B.
DISCRIMINATE MODE.
The Discriminate Mode is motion based, and requires that the searchcoil be moving slightly
for target detection. There is no threshold sound present as in the All Metal Mode. The notch tone target ID features
works in the Discriminate Mode even if the notch mode switch is in the off position. The notch level control setting
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
would be rejected by a properly adjusted notch level in the notch reject mode.
If the notch level were set too high, the notch 'window' would not include the complete unbent older style pulltabs and
may start to eliminate pennies.
If the notch level were set to low, the 'window' may eliminate the nickel, and the newer style of lift ring tabs would be
detected.
Beginning operation in the notch reject mode with the notch level control set at the 6 or 7 mark should put the notch
window reasonably close to the desired response. If you begin to find the complete older style pull tab, you should turn the
notch level down slightly, and continue searching. If you are finding the newer style lift rings which have been torn off the cans,
it's a signal to raise your notch level slightly.
No matter which way you adjust the level, do it in very small steps, since this setting is fairly critical.
FIELD USE
The detector should be held in a position that is comfortable for you. Swing the detector from side to side in about a three
foot arc, overlapping succeeding strokes well. This motion is called a “sweep.” The Golden Sabre II 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 in Discriminate may even cause a loss of depth in heavily mineralized locations.
It would be helpful to bury some coins and trash metal junk items in an area that you know is clear of other metal
objects, and then try the unit in its various modes. Check the area in All Metal Mode first to be sure its clear of trash then
bury the targets at least a foot apart, and from 2 to 6 inches deep to start. Make a map of the test bed to be sure you know
what each target is and how deep it is. Practice on these targets to familiarize yourself with your detector’s target response.
This will also help you learn the proper sweep rate for best operation.
Regardless of which mode you are using, try to keep your searchcoil height constant and close to the ground. Most
people tend to raise the coil at the end of a sweep, much like a pendulum, especially if they are hurrying. Try to avoid this, as
any increase in height will cause a corresponding loss of depth.
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
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 larger coil is 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.
PINPOINTING
The sweep speed of the Golden Sabre II is slow enough to allow pinpointing in the Discriminate Mode, but will require a
little more practice. Move the coil slowly from side to side and then from front to back over the target. Raising the coil slightly
and slowing the sweep speed will narrow down the detection area enough that it's easy to tell where the coil center is at the
instant of the sound.
Another easy method is to sweep the coil from side to side across the target in very short sweeps, as you slowly move
forward and backward across the target. Slow down the sweep rate and shorten the sweeps until you just barely get a
response at one spot. The target will be directly below the coil center at this response time. In fact, you will be looking at the
exact spot in the ground where you want to dig, because of the open coil center.
The easiest way to pinpoint for most people will be to switch to the All Metal, since no motion is required. To pinpoint a
target that doesn't saturate the audio, just move the coil forward and back, and side to side until you get the strongest sound.
The target will be directly below the coil center. If the audio saturates over a large area, simply push the mode switch to the
retune position momentarily over the area to retune the detector. This will narrow its field of response to allow you to once
again seek the area of strongest response. It may be necessary to retune more than once with this technique. With a
moderate amount of automatic tuning, the detector itself will be attempting to to tune back to threshold, which automatically
narrows down its area of strongest target response.
RECOMMENDED RECOVERY METHODS
Always obtain permission from the person in charge before hunting on private property, schoolyards, parks, churches, or
state parks. Even when relic hunting in the woods, NEER LEAVE A HOLE!, or damage anything on the property.
PROTECT YOUR HOBBY FILL ALL HOLES
BATTERY REPLACEMENT
The Golden Sabre II has an automatic battery test sequence with each initial power turn on. To check the batteries
simply turn the detector off momentarily and then back on.
When testing the batteries, be sure that the Mode Switch is
in the Disc position, so that the All Metal threshold signal doesn't add to the battery test signal.
The detector should
beep loudly for about 3 to 5 seconds, with the sound slowly fading into silence, if the batteries are fresh. As the batteries age,
this sound less intense, and fades out quicker. When you just hear a brief buzz, or not audio at all, replace the batteries.
To replace the batteries, pull the large knob on the battery door on the rear of the unit. The entire door will pop out.
Remove the battery packs from the detector, and then remove the battery packs. Place the new penlight batteries into the
packs, being sure that you observe the polarity indicators on the inside of the packs. Slide the packs back into the detector.
Install the battery door back onto the chassis, making sure that the plungers are still pulled out. Then push the plungers back
in to lock the door in place.
We recommend when you replace the batteries, that you change all at the same time, and that you always use good
quality alkaline batteries.
GENERAL CARE AND USE
If the detector is to be stored for a long period of time, it is best to remove the battery pack from the detector. This will
prevent internal damage to the detector if the batteries should leak. The searchcoil is waterproof and may be submerged in
either fresh or salt water. Caution should be exercised to prevent water from entering the chassis, where it could damage the
electronic circuitry. After the coil is used in salt water, the coil and lower stem assembly should be rinsed well with fresh
water to prevent corrosion of the metal parts. There are several good books to help the beginner learn how to use the detector,
where to search and how to recover a target without damaging the environment. A good coin shooter can recover a lot of finds
and leave the area looking as though he had never been there. Above all, always fill your holes when you have recovered the
target.
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.
