more easily. Have the narrow side of the coin parallel with the
search coil will cause test error, and target arrow might be
flash and jump.
5. In ALL METAL Mode, move a test sample above the flat side
of search coil from a higher location (above than 1 foot) slowly
close to the search coil. The detector emits a tone when
detects the target, and DEPTH indicator shows relative value.
All samples sound one tone in this mode.
5.3 OUTDOOR TEST AND PRACTICE
PINPOINTING (motion mode)
Accurate pinpointing takes practice and is best accomplished
by crossing sweep the target area.
1. Once a buried target is indicated by a good tone response,
continue sweeping the coil over the target in a narrowing
side-to-side motion.
2. Take visual note of the place on the ground where the
"beep" sounds.
3. Stop the coil directly over this spot on the ground.
4. Now move the coil straight forward and straight back
towards you a couple of times.
5. Again make visual note of the spot on the ground at which
the "beep" sounds.
6. If needed, cross sweep the target in "X" pattern at different
angles to "zero in" on the exact spot on the ground at which
the "beep" sounds.
COIL MOVEMENT
When swinging the coil, be careful to keep it level with the
ground about 1-1.5cm from the surface. Never swing the coil
like a pendulum. Raising the search coil while sweeping or at
the end of a sweep will cause false reading.
Swing the search coil slowly, overlapping each sweep as you
move forward. It is important to sweep the coil at a consistent
speed over the ground as you search. After identifying a
target, your sweep technique can help in identifying both the
location and the nature of the target. If you encounter a weak
signal, try moving the coil in short, rapid sweeps over the
target zone; such a short rapid sweep may provide a more
consistent target identification.
Most worthwhile objects will respond with a repeatable tone.
If the signal does not repeat after sweeping the coil directly
over the suspected target a few times, it is more than likely

trash metal.
Crossing the target zone with multiple intersecting sweeps at
multiple angles is another way to verify the repeatability of
the signal, and the potential of the buried target. To use this
method, walk around the target area in a circle, sweeping the
coil across the target repeatedly, every 30 to 40 degrees of the
circle, about ten different angles as you walk completely
around the target. If a high-tone target completely
disappears from detection at a given angle, chances are that
you are detecting oxidized ferrous metals, rather than a silver
or copper object. If the tone changes at different angles, you
may have encountered multiple objects. If you are new to the
hobby, you may want to dig all targets at first. With practice
in the field, you will learn to better discern the nature of
buried objects by the nature of the detector's response.
You may encounter some false signals as you proceed. False
signals occur when the detector beeps, but no metal target is
present. False signals can be induced by electromagnetic
interference, oxidation, or highly mineralized ground soils. If
the detector beeps once, but does not repeat the signal with
several additional sweeps over the same spot, there is
probably no target present.
When searching very trashing ground, it is best to scan small
areas with slow, short sweeps. You will be surprised just how
much trash metal and foil you will find in some areas. The
trashiest areas have been frequented by the most people, and
frequently hold the most promise for finding the most lost
valuables.
5.4 GROUND BALANCING
Before using the ALL METAL mode, it is necessary to "Ground
Balance" your detector, this ground balancing adjustment
offsets the effects of minerals and salts in the ground.
To GROUND BALANCE your detector:
1. Use the ALL METAL mode to find a patch of ground which is
free of metal objects. You will use this section of ground to
test the detector. The presence of any metal objects in this
area will interfere with this procedure.
2. Lift the search coil waist high in the air.
3. Begin with the ground balance (GND BAL) KNOB in the P
position. Rotate slightly the GND BAL KNOB from P counter
clockwise.
4. Press GND TRAC .
5. Lower the search coil to the ground, maintaining it elevated
about 1-1.5cm above the surface (be sure that this ground does
not contain metal).
- If the detector emits sound with the search coil 1-1.5cm over
the ground, repeat the above steps 3 and 4.
- If the detector remains silent with the search coil 1-1.5cm
over the ground, no further adjustment is necessarythe
detector is "GROUND BALANCED".
It is important to move the GND BAL knob in small increments
in order to find the first setting (moving clockwise) at which
the detector remains silent. To insure yourself of the optimal
adjustment, move the KNOB slightly clockwise from a silent-
adjusted position to check for the most clockwise silent position
possible. If the KNOB is over-adjusted in the clockwise
direction, the detector can lose sensitivity.
As your search takes you to different areas, verify the ground
balance setting periodically using the above procedure. Within
a geographical area, ground conditions can change. Varying
elevations, proximity to water, and concentrations of rock, sand
or clay can all affect ground condition and sometimes require
recalibration with the ground balance knob.
5.5 PINPOINTING (non-motion mode)
Coil sweep technique is not important in this mode. Rather,
user retuning is critical. The detector does not automatically
adjust to changing ground and environmental conditions; the
operator is required to make the adjustment.
RETUNING
Keep the coil still, just above the ground surface. Make sure
that the spot on the ground you chose for tuning did not
contain metal; pass over the area with the coil again to insure
that the detector does not emit a tone.
Detection Field : The detection field depends on the size of
the target.
Large Objects: After detecting a target, LCD displays
sensitivity level and speaker beeps. If lift the coil off the ground
to a distance around 2cm, the tone does not fade, you have
detected a large or irregularly shaped object. Further lift the
coil off, increments on LCD decreases obviously and the sound
of beeps reduces rapidly. Outline the object with slow coil
movements at the same height.
Small Objects: After detecting a target, LCD displays a low
sensitivity level and the speaker emits a faint sound. While
maintaining the coil at this height above the ground, move
the coil from side-to-side. Note the spot where the tone is
loudest, and the sensitivity level is largest (usually
increments on LCD changes more sensitive than the sound
changes). Then move the coil toward the ground to zero-in
on the target's location. A coin-size object will be detected
when the object enters the range of the inner coil.

5. CARE AND MAINTENANCE

The following suggestions will help you care for your metal
detector so you can enjoy it for years.
Trouble Shootings:
1.Detector emits false signal in field use.
Sensitivity is set too high, please lower the sensitivity till the
false signal disappears. Move the search coil slowly. Oxidized
metal may cause the false signal. If the signal is not
repeatable when search coil swept over a target, the target
usually is a trash.
2. CD displays multiple target categories or emits several
sounds at one time. There might be over one kind of metal,
or the detector cannot identify the target. Sometimes,
oxidized metal also cause the excursion of target arrow and
tone. Too high sensitivity is another probable reason.
3.Detector works unstable or read by mistake.
There might be another metal detector working or electric
line nearby.
- Handle the metal detector gently and carefully. Dropping it
can damage circuit boards and cases and can cause the
metal detector to work improperly.
- Use and store the metal detector only in normal
temperature
environments. Temperature extremes can shorten the life of
electronic devices, damage batteries, and distort or melt
plastic parts.
- Keep the metal detector away from dust and dirt, which can
cause premature wear of parts.
- Occasionally wipe the metal detector with a damp cloth to
keep it looking new. Do not use harsh chemicals, cleaning
solvents, or strong detergents to clean the metal detector.
CAUTION:
· The search coil is water proof, and it can be completely
under the fresh water or sea water. Please be careful to avoid
the water enter into machine body. Sea water may erode the
search coil. Please always use fresh water to clean the search
coil after detection in sea water.
· Change or damage the inner components will cause the
detector fault, and such fault is NOT WITHIN our warranty.
