Deep Search VI OPERATOR INSTRUCTION MANUAL
GENERAL DESCRIPTION
The Deep Search VI is a Transmitterreceiver (TR) Metal Detector, operating in the very low frequency (VLF) portion of the
RF spectrum. The detector utilizes the natural phenomena of the phase delay of all targets to provide mineralfree or ground
compensated response in the normal mode of operation, or to provide discriminate capability in the discriminate mode.
The design of the Deep Search VI was implemented not only to provide excellent sensitivity, but to provide a unit which is
easy to use for both the beginner and the expert treasure hunter.
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
Assembly of the Deep Search VI is very simple, and requires no special tools. The only assembly required is to mount
the searchcoil to the end of the lower stem and install the lower stem and lock nut assembly to the upper stem.
1. 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.
2. Insert the coil mounting screw through the coil and pole tip. Be sure the internal tooth lockwasher is on the screw
head side. The screw head should be on the side of the searchcoil where the cable comes out.
3. Install the thumb nut on the screw and tighten by hand.
4. The knurled locknut is installed on the upper stem to protect the threads during handling and shipment. Remove the
locknut and slide it onto the lower stem as shown. Be sure the lock ring is inside the locknut or behind it, so that it will
be pushed into the locknut when the locknut is reinstalled on the threads.
5. Insert the lower stem into the upper stem, push the locknut up to engage the threads, and tighten it finger tight.
6. Wind the searchcoil cable around the pole, and install the searchcoil connector into the connector on the front of the
chassis. Tighten the connector finger tight.
ADJUSTMENT
The searchcoil angle and stem length should be adjusted so that the unit is not uncomfortable or tiring after long periods
of use. The stem length is adjusted by loosening the knurled locknut and extending or collapsing the stem length until the unit
can be held about an inch off the ground while standing erect. Adjust the angle of the searchcoil, so that the coil is parallel to
the ground. Tighten the searchcoil thumbnut and stem locknut by hand to maintain this setting.
The function of the front panel controls of the Deep Search VI are as follows, beginning in the lower left hand corner, and
proceeding in a clockwise direction.
1. Mode Switch. This switch is a three position toggle switch which selects the basic detector operation mode.
A.
Battery Test. This position is used to check the condition of the batteries. The battery test should be performed after the detector has
been on for about 10 minutes, and with a moderate to heavy amount of sound. A meter reading of .6 or above indicates the battery strength
is adequate for proper operation. If the meter reading is below .6, replace the batteries.
B.
Norm. This position selects Normal or All Metal mode. In the Normal position, the detector can be adjusted to ignore ground
mineralization for maximum depth, but the detector will not discriminate against unwanted metals such as iron, bottle caps, etc.
C.
Disc. This position selects the Discriminate mode of operation, whereby response to unwanted metal objects such as iron, bottle caps,
thin foil pieces, etc., can be controlled. Ground mineralization will affect the operation of the detector in this mode.
2. Disc 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 other 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 a negative or "nulling" response.
3. Tuning. This control is used to tune the detector to its most sensitive setting, regardless of which mode is used.
Since the target response of a TR detector is an increase in sound level, the ideal setting for maximum depth is so that

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 other 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 a negative or "nulling" response. 3. Tuning. This control is used to tune the detector to its most sensitive setting, regardless of which mode is used. Since the target response of a TR detector is an increase in sound level, the ideal setting for maximum depth is so that the detector is just beginning to make sound. This "threshold" setting should be maintained at all times, as operating the detector completely silent means a deep target may have insufficient response to drive the detector out of the quiet region and into "threshold". 4. Sensitivity. This control adjusts the detector's sensitivity to ground effects due to mineralization, as well as its sensitivity to metallic targets. In the normal mode of operation, the detector will ignore effects of mineralization if it is properly adjusted, so the detector can be operated in maximum sensitivity in almost any ground in the mode. In the discriminate mode, the ground effects are not ignored, so the detector may perform better in heavily mineralized ground at reduced sensitivity. 5. Ground Adjust. This control is used to adjust the detector so that it does not respond to the mineralization in the ground, when used in normal mode. 6. ON/OFF Volume. This control adjusts the amplitude of the audio signal, as well as controlling the power to the unit. When using the internal speaker, the volume control should be at its maximum clockwise setting for maximum depth. When using headphones, the internal speaker is disconnected, and the volume control should be set for maximum comfortable volume. 7. Tuning Push Button Switch. This switch is located in the end of the hand grip where it is easily depressed with the thumb. This switch is used to reset the detector tuning to the desired threshold anytime conditions cause a tuning change in the detector. TUNING A. Normal Mode Tuning. Turn ON/OFF Volume control fully clockwise. Turn the Ground Adjust control to about 6. Set the sensitivity control to mid range (pointer straight up). Hold the Tuning push button switch in. Turn Tuning control as required to get a moderate audio sound and a meter reading of about .4. ...
- Page 3 If the meter reads less than .6, the batteries should be replaced to ensure best performance. To change the batteries, depress the chrome buttons on each side of the detector, and slide the battery cover off the back of the chassis. The batteries are contained in a plastic holder just behind the cover. 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 that are embossed in each battery compartment of the battery pack. Replace the pack into the holder, and replace the battery cover by depressing the chrome buttons as the cover is slid back into the chassis. 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, or from entering the upper stem, where it could damage the push button or leak into the chassis. 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 Deep Search VI 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. The 7" coplanar searchcoil furnished with the Deep Search VI is optimized for coin hunting, but will work as well as most 8" coils for relic hunting. The serious relic hunter will probably want to consider the larger wide scan coils available for the DEEP SEARCH VI. They offer increased depth for relics, but at a sacrifice in the discrimination ability. HAPPY HUNTING, and thank you for purchasing a TESORO.
