The Silver Sabre has only three controls, and they are all mounted on the front panel of 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. 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. MODE CONTROL. This toggle switch is used to select the All Metal mode of operation or the Discriminate mode. In All Metal, the detector will find not only the highly conductive nonferrous metals, but will also find the ferrous metals. This mode will be ideal for relic hunting or ghost town searching, since many desirable artifacts (such as guns) are made of iron and steel. In the Discriminate mode, the detectors response to unwanted trash can be controlled to eliminate digging much of the common metallic trash items found in likely hunting spots. The detector may beep briefly when the switch is changed, but is ready for operating in the selected mode instantly.
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.

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 Silver Sabre 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.

If there is any doubt whether a target is good or not, DIG IT. For this same reason, in the Discriminate Mode, it is best not to use a higher DISC LEVEL setting than necessary. Nickels and most smaller rings are rejected when the DISC LEVEL is set to reject pull tabs on any metal detector that is a TR Discriminator like the Silver Sabre. If you don’t dig any junk at all, you are surely passing up a lot of good finds as well. Set the DISC LEVEL only high enough to suit the conditions where you are searching.

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 Silver Sabre is furnished with an 7" 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", 8 1/2", and 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 8 1/2" coil will yield about an extra inch in depth in most areas, and is an excellent coinshooting coil in relatively clean areas. The increased surface area makes pinpointing a little more difficult, and allows trash to hide the good targets a little easier. Both the 8 1/2" and 11" coils are excellent relic hunting coils, can provide greatly increased depth on larger targets, especially in the All Metal mode where surface junk won't hide the deep targets.

PINPOINTING

Pinpointing a target is probably best accomplished by "X-ing" the target with the searchcoil. Remember that the detector will beep just as the target passes the center of the searchcoil. Swing the searchcoil over the target from side to side and then front to back until you can "zero in" on the exact location of the coil center when the detector beeps. Slowing the sweep speed down will help you pick out the center of the X because the target response will be reduced at very slow speeds and it's easier to correlate the sound with the coil center at slower speeds.

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.

Reducing the sensitivity and raising the searchcoil can also help pinpoint by narrowing the response to the target. Practice pinpointing often, and you will soon become more accurate and faster. Be sure to fill all holes after you recover the target. Your local dealer should be able to point out the preferred methods of digging in your area. Two methods are shown here which work most everywhere. Be sure to protect your hobby by leaving the site cleaner than you found it and with all holes filled.

Your Silver Sabre is equipped with an automatic battery test circuit so that you can always be sure you are getting top performance from it. The batteries should be checked after the detector has been on for about 10 minutes, and then periodically as you are using it for long periods. To activate the batter test circuit, simply turn the detector off momentarily and then back on. The detector should beep loudly for about 4 or 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 front of the unit. The entire door will pop out. Remove the battery pack from the detector, and then remove the batteries from the pack. Replace the new penlight batteries into the pack, observing the polarity indicators embossed into the insides of the pack. Slide the pack back into the detector, making sure that the battery clip lead is connected. Install the battery door flange into the top of the cutout in the chassis, making sure that the plunger is still pulled out. Then push the plungers back in to lock the door in place.

Should you desire to do so, rechargeable Nickel-Cadmium batteries can be substituted for standard 9 volt cells. Individual 9 volt size cells are readily available at most electronic supply stores, as well as the chargers for them, and they can be inserted into the standard holder used in your Silver Sabre. The initial battery check reading will be slightly lower, but will not drop as much with use, until the batteries are completely discharged.

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 Silver Sabre 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.
