Deep Search VII OPERATOR INSTRUCTION MANUAL

GENERAL DESCRIPTION

The Deep Search VII 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 VII 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 VII 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.

Controls

The function of the front panel controls of the Deep Search VII 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.

Mode Switch. This switch is a three position rotary switch which selects the basic detector operation mode.

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.

Auto Tune. In this position, the detector will have a very slight amount of automatic tuning. The auto tune is designed to help compensate for slowly changing ambient conditions such

as changes in the height of the grass, or temperature changes. it is not fast enough to cause any problems due to overshoot falsing on trash items, and is recommended for almost all

uses.

Normal Tune. In this position, the slow auto tune is disconnected, so the unit will not tend to correct for changing ambient conditions.

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.

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".

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

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". 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. 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. 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. Mode Control/Tuning Switch. This toggle switch is located in the end of the handle where it may be operated with the thumb and first finger of the hand holding the detector. When the switch is pushed down, the detector will select the Discriminate Mode of operation and tune itself. When the switch is pulled up, the detector will select the Normal mode of operation, and tune itself. There are arrows silk screened on the front panel to help remind you which way to push the switch. The arrow pointing down next to the Disc Level control, means that Discriminate mode is selected when the switch is pushed down. The arrow pointing up next to the Ground Adjust control means that the Normal mode is selected when the switch is pulled up. TUNING 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 Mode Control/Tuning Switch up. Turn Tuning control as required to get a moderate audio sound and a meter reading of about .4. Hold the coil about 2 feet above the ground, and release the Mode Control/Tuning Switch. Lower the searchcoil to within an inch of the ground, and observe meter reading change and audio change as the coil is lowered. If the meter reading and the sound increase, turn the Ground Adjust control down slightly (counterclockwise). If the meter reading and the sound decrease, turn the Ground Adjust control up slightly (clockwise). ...
Page 3 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 VII 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 VII is optimized for coin shooting in areas with a moderate to high amount of trash. In areas with relatively little trash metallic items the 8 1/2" Wide Scan coil will provide good depth on coins, and of course it should be used for relic hunting, as it will give better depth for larger objects.
