1. See the above figure, the fixing ring is placed around the lower stem,
and its flat side faces the upper stem.
2. The two protrusions on the inner surface of the threaded ring must fit into
the two holes near the lower end of the upper stem.
3. If you want to use the arm cuff, insert it into the corresponding hole
beside the handle to a desired depth and then pull down the end of the arm
cuff lock to lock the arm cuff. Once inserted, the arm cuff can not be
disconnected from the upper stem.
4. To avoid damage, do not pull the search coil cable with force. When
connecting the cable to the socket on the rear of the control box or
disconnecting the cable from the socket, hold the cable plug instead of the
cable.
PANEL OF THE CONTROL BOX

3. ALL METALS/DISC Knob

- 7 -
Counterclockwise turn this ALL METALS/DISC knob to the "ALL METALS" position.
The knob clicks and the detector stays in the ALL METALS detection mode.
When this knob is in the "ALL METALS" position, clockwise turn it and, after it
clicks, the detector is in the DISCRIMINATION ( DISC ) mode.
4. POWER/VOLUME Knob
Used to turn on or off the detector or select a desired alarm volume.
To turn on the detector, clockwise turn this POWER/VOLUME knob until it clicks.
Continue to clockwise turn this knob to increase the alarm volume.
To decrease the alarm volume, counterclockwise turn this knob. To turn off the
detector, counterclockwise turn this knob until it clicks.
5. SENS Knob
Used to adjust the sensitivity of the detector.
You can clockwise turn this SENS knob to increase the sensitivity, or
counterclockwise turn this knob to decrease the sensitivity.
6. Low Battery Indicator
When the batteries are not high enough, this low battery indicator will light up as
an indication and you must replace the batteries immediately; otherwise the
detector's detecting ability will decrease or the detector will not be able to work
normally.
OPERATING INSTRUCTION
Preparation prior to metal detection
Before beginning an outside search, test the detector with the following metal
samples:
•An iron nail
•A five-cent coin ( nickel )
•A one-cent penny ( zinc coin, after 1982 )
•A 25-cent silver quarter

- 8 -
Place the metal detector on a wooden or plastic table with the search coil roughly
perpendicular to the table surface ( see Figure 6 ). Make sure the table is far away
from TVs, computers, or any device that can cause electromagnetic interference.
Note: To avoid interference, remove any watches, rings, or other metal objects on
your fingers and hands.
Testing the detector in the All METALS mode
Counterclockwise turn the ALL METALS/DISC knob until it clicks. Now the
detector is in the ALL METALS mode. Gently turn the SENS knob completely
clockwise until it reaches the end.
Now the detection sensitivity is at the highest level. Refer to Figure 6, respectively
pass the metal samples ( the iron nail and 3 coins ) across the search coil at a
distance of 5cm to 8cm. When any of the metal samples passes across the search
coil, the detector should beep and the meter pointer should deflect rightwards.
When the detector stops sounding, the meter pointer should return to its original
position quickly.

- 9 -
The ALL METALS mode allows the detector to achieve the maximum detection
depth possible.
Note: During test, the metal sample which you are using must be in motion;
otherwise the detector will not respond to this metal sample.
Testing the detector in the DISCRIMINATION mode
Make sure that the ALL METALS/DISC knob is in the "ALL METALS" position,
then turn the knob clockwise until it clicks. Now the detector is already in the
DISCRIMINATION mode. In this mode, you can use the ALL METALS/DISC knob
to search for specific metals by having it ignore other kinds of metals. At the
present knob position, where the knob just clicked, the detector will respond to
ANY metal object and the meter pointer will swing to the right when the detector
beeps.
Note:
The Figure 7 on the right
shows the knob positions
for some often encountered
metals. If the ALL METALS/DISC
knob is in one of these
positions, the corresponding
metal will be ignored during
scanning. The specifications
or descriptions on the figure
are not accurate and are for
non-critical reference only.

1. To adjust the settings to prevent the metal detector from detecting iron metals,
set both the VOLUME knob and SENS knob at midpoint ( or a higher setting ).
2. Then set the ALL METALS/DISC knob to about " 12 o'clock ". See Figure 8.
3. As a test, sweep the iron nail sample across the search coil at a distance of
about 5cm to 7.5cm, the detector will not beep and the metal pointer will not deflect,
but the other metal samples ( the three coins ) will cause the detector to beep and
the meter pointer to deflect rightwards when they are respectively swept across
the search coil.
4. To have the metal detector ignore nickel metals, set the ALL METALS/DISC
knob to about " 3 o'clock " ( see Figure 9 ). Sweep the nickel across the search coil
at a distance of about 5cm to 7.5cm; the metal detector will not respond to the
nickel or the iron nail. But it will respond to the other samples.

- 11 -
5. To prevent the zinc penny from being detected, set the ALL METALS/DISC
knob to about " 5 o'clock " ( see Figure 10 ). By now, only the 25-cent silver quarter
should be detected.
Note: The discrimination position of aluminum is similar to that of silver. So both
metals will be detected at the same time. The discrimination position of gold is
similar to the nickel setting.
Through the above tests, you can quickly know the performance of the detector
and know how to use the detector.
Tip: During test, the metal sample which you are using must be in motion.

Detecting metallic object with the detector
After you finish all the tests mentioned above and have set the detector to meet
your need, you can start to detect metallic objects.
Turn on the detector, and set it in the ALL METALS mode. Adjust the SENS knob to
a desired sensitivity setting, and be far away from any external interference
source.
During detection, keep the search coil height approximately 3cm to 5cm above the
ground and parallel to the ground at all times for best detection results, walk slowly
as you scan slowly the search coil in a straight line from side to side.
When you detect a metallic object, you can use the DISCRIMINATION mode to try
further identification or discrimination, if necessary.
Metal detection is a careful, difficult job. Because there may be iron nails, metallic
oxides, and metal scraps in soil, it may be necessary to perform detection many
times in a same location to get an accurate result, especially in an area where the
soil contains complex mineral substance constituents.
Note:
1. Because many factors ( degree of oxidation of metallic object, metal impurities

- 13 -
in soil, soil moisture content, etc ) can affect metal detection/identification in
DISCRIMINATION mode, the results of metal identification/discrimination are not
guaranteed to be correct.
2. During detection, the search coil must be in motion. If the search coil is still, the
detector can not detect metal normally.
3. The detector can work with the earphone ( optional ). To use the earphone, just
insert the plug of the earphone into the earphone jack on the control box, the
loudspeaker in the control box will be disabled automatically.
Note:
For safety, do not use earphone near traffic.
To avoid hearing loss, do not use earphone if using it makes you feel
uncomfortable.
DUAL-FREQUENCY AUDIO ALARM FUNCTION
The detector has a dual-frequency audio alarm function. When it detects a ferrous metal
object, it emits a tone of 660Hz audio signal, and when it detects a non-ferrous metal
object, it emits a tone of 2000Hz audio signal.
BATTERY REPLACEMENT
When the low battery indicator lights, the batteries are not high enough and must
be replaced immediately.
To replace the batteries, turn off the detector first. Then slide the battery cover
( see Figure2 ) downwards to remove it. Replace the old batteries with new ones of
the same type, make sure that the polarity connections are correct ( see the
polarity indications at the bottom of the battery compartment ). Reinstall the battery
cover.

NOTE
1. To preserve battery life, turn off the detector when not in use.
2. If the detector can not operate normally, a possible cause is that the batteries
are exhausted.
3. Protect the plug of the search coil cable from damp; otherwise the detector may
lose its detecting ability. Dry the plug as needed.
4. The control box is not waterproof. Protect the control box from water, and do not
use the detector in the rain.
5. Do not place the detector in any high-temperature environment.
6. Do not tamper with the circuit of the detector.
7. Do not pull the search coil cable with force.
8. Handle the detector gently. Do not bump, drop or abuse the detector.
9. When you turn a knob, do not apply excessive force.
WARNING
Any metal detector may discover underground power lines, explosives or other
items which when struck could cause personal injury. When searching for metals,
observe these precautions:
1. Do not search in an area where you believe there may be shallowly buried
underground electric lines or pipes.
2. Avoid striking any line known to be or suspected to be carrying electrical power.
3. Do not disturb any pipeline, particularly if it could be carrying flammable gas or
liquid.
4. Use reasonable caution when digging toward any target, particularly in areas
where you are uncertain of underground conditions.
5. Observe all national, state and local laws while detecting.
