TROUBLE SHOOTING GUIDE
TERMINOLOGY
The following terms are the common terminology among metal detector.
● Motion Mode
This is one of the circuit operation modes in the metal detection technology.
When detecting, you should move the search coil continuously. In general,
motion mode can reduce the effect of the soil mineralization, and it will have
better discrimination ability.
● Non-motion Mode
This is another circuit operation mode in the metal detection technology.
When detecting, you do not need to move the search coil continuously, as
long as the search coil approaches the metal at a certain distance. In the
non-motion mode, the detector can’t discriminate the metal types.
● Elimination
This mode of operation eliminates a particular metal type. During this
process, when the detector find the specified metal, the detector will not
send prompt signal, such as light, electricity and sound.
● Discrimination
To differentiate the types of metals, the detector will sound a different tone or
give a different indication, as it eliminates the specific metal. It is an
important ability of the detector referred as “discrimination”.
● Iron
Iron is a common metal. It’s usually not the detection target, undesirable iron
objects contains iron nail, bolts, old cans, caps and so on. But some valuable
relics may also be made of iron, such as old ornaments, old armature and so
on.
● Ferrous
Metals which are made of, or contains iron.
● Trash metals
Caps, pull-tabs, S-caps are the most bothersome trash items for treasure
hunters; you should eliminate them during detecting. But some other
valuable objects have a similar magnetic with the above trash metals, and
will also be eliminated as trash when discriminating.
● Pinpoint
Pinpoint is a process of determining the exact location of the buried metal
object. On this motion mode, you need to move the search coil continuously
when detecting, if it’s hard to determine the exact location of the buried
metals. In the Pinpoint mode, select Non-motion technology to let the center
of the search coil be aligned with the location of the buried metal, to help
your excavation.
● Ground balance
Metals buried in the earth mineralized material in the soil affect metal
detection. The ground balance will eliminate or weaken the shielding effect of
the mineralized soil. The ground balance is divided into built-in ground
balance and adjustable ground balance.
● Coins depth
The coins depth the detector referred to, which is generally the approximate
distance that the 25￠silver is in the neutral soil or in the air. It’s not an exact
depth.

Note: When the power supply is switched on within a few seconds, the metal
detector will go into self-inspection program. Don’t let the search coil
approach the metal, nor carry out any operation, until the self -inspection is
completed. This action is done when you hear a beep tone.
Assembly
1. Loosen the two triangular fasten buttons under the control box, insert to
the bracket, and lock the two triangular buttons. See Fig.1.
Fig.1
2. Press down the silver shrapnel on the plastic stem, and insert it to the
black aluminum stem. When the silver shrapnel popping up from the black
aluminum stem, you can use it. The black aluminum stem is with four holes,
for you to adjust the length of the connecting rod, so that you can
comfortably erect and straighten your arms, and keep the search coil away
from the ground about 1/2 inch. See Fig.2, 3.
3. Wind the electronic line on the search coil around the aluminum stem;
keep the elastic moderate, so that the cable won’t sway.
4. Relax the nuts at the two ends of the search coil, and adjust the location of
the search coil, to let the search coil be parallel with the ground. Be careful
not to mistake the location of the search coil (See Fig.3).
Fig.2
Battery
Use 6 alkaline AA batteries.
1. Press the “key” on the battery cover in the direction of the arrow, pull out
the battery cover.
2. Insert 6 AA batteries as indicated by the polarity symbols marked inside
the battery box
3. Close the battery cover. When a KATA tone being heard, which means the
battery cover has been covered well. Ensure the direction of “UP” on the
battery cover is followed.
These batteries are expected to last for about 40 hours. If you don’t use the
detector for a long time, please remove the batteries from the battery box.

Panel and LCD
All the controller adjustment displays on the LCD, and all the detection
results are also shown on the LCD. LCD See Fig.6
● Mode indication cursor: Indicate the four kinds of operation modes. Make a
switch through the MODE button.
● Target ID pattern: It’s located above the LCD screen. It indicates the target
metal you’re looking for. When detecting a metal target, the target ID cursor
(upper scale) shows the metal patterns or the words.
● Target ID cursor (upper scale): it’s in the shape of .The upper scale
consists of 6 segments. When the target ID cursor is lighted, this indicates
the probable type of the detected metal.
The three kinds of prompted signal, corresponding to the target ID cursor.
See the table below:
Note: The position of the target ID cursor may change as it is affected by the
soil composition and the same material metal have in different soil.
● Target identification cursor (lower scale): It’s in the shape of,6 segments
making up the lower cursor, which indicates the material types of the
detected target objects. In the ALL-METAL mode, the 6 segments are all
lighted. While in other modes, when a certain target identification cursor is
extinguished, which indicates this type of metal isn’t in the detection range,
which means this type of metal is eliminated. In the PINPOINT mode, the
Target identification cursor is useless.

● Target Digit Cursor: double digit, 10-99 indicates the material of the metal.
When detecting, the digit may have some changes, which depends on the
composition of the target, the size, the shape, the distance from the search
coil and the speed of scanning. The surrounding soil can also affect the
value. Refer to the following table as a preliminary guide.
● Coin depth indication cursor: it is used together with the sensitivity cursor.
It is divided into 2”, 4”, 6” and 8+ four segments. It indicates the approximate
depth of the 25￠silver in the neutral soil. As the size, the angle and the
material of the target, the composition of the soil will all affect the indication
value.
● PINPOINT mode cursor: it is used with the digit cursor. Touch the P-P
button, displaying the “PP” character, and appearing a brief flash. At the
moment, the unit will be balance the surrounding environment, when PP
displays stable, this indicates the pinpoint (PP) state.
● Signal strength cursor: left and right total has 5 gears, in the Pinpoint state
indicating the signal strength.

● Sensitivity indication cursor: It’s divided into 4 gears, when they are all
lighted; the sensitivity is at the highest. Adjust the sensitivity by the SENS
button. It is useless in the PINPOINT mode.
● Battery power cursor: 3 gears indicate the battery power. When all the
cursor is lit, this indicates power is enough. While the entire battery indicator
is extinct and the battery pattern is glimmered, it’s time to replace the battery
right away.
Controller
All the controllers are on the panel.（See Fig.7）
● Power button: press the button, the power is on,and press it once
more,the power is off.

modes circularly.Boot setting is in the ALL METAL mode.
ALL METAL-The detector is in the ALL METAL mode,and to all kinds of
metals,the detector will make a respond.
JEWELRY-the detector eliminates iron,which means it won’t make a
respond to the iron,but only be in respond to other metals.
MEMORY- the detector will memory the selected metal,and only be
respond to this metal.Press the MODE button once,the detector goes into
the MEMORY state(the MODE cursor pointing to MEMORY),at this
moment,the six lower cursors all displaying,and the detector goes into the
memory state.Scanning above the search coil with the selected metal,the
detector will memory this metal,and will only be respond to this metal.

Press the MODE button again,logging out the memory mode,return to the
state that all of the 6 lower cursors displaying,and carry on the second set.If
no longer set,press the MODE button again,exit the MEMORY state,and
enter the next operation mode.
COINS- the detector eliminates the iron,pull-tabs and S-CAP,only be respond
to all kinds of coins.
● SENS Button:choose the 4 levels with SENS button.Boot setting is at the
middle value(the second gear).The highest sensitivity is the fourth
level.When there is interference,setting the sensitivity lower properly.In the
PINPOINT mode,the SENS button is useless.
● PP Button:touch the “PP”button,the detector turns into PINPOINT
mode,and it no longer has the ability to identify.At this moment,the PP cursor
is lighted,and indicates the signal strength.The more close to the metal
target,the more the strength cursor is lighted,the more louder the sound is,in
order to locate the target position accurately.Touch the “PP”button again,exit
the PINPOINT state.
