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
