FEATURES

With your metal detector, you can hunt for coins, relics, jewelry,
gold, and silver just about anywhere. This metal detector is
versatile and easy to use. Features include:
Two operating modes: All Metal and Disc.
ALL METAL – Lets you search for different types of metals with
automatic ground balance and high sensitivity. This is the best
operating mode.
DISC – Discriminates among different types of metals being
detected.
Volume – Adjusts volume levels for speakers and headphones.
Headphones Jack – Connects headphones (not supplied) to the
metal detector.
View Meter and Pointer – The meter pointer swings to the right if
metal is found.
Waterproof Search Coil – Lets you search for metal objects under
shallow water.
Note: The search coil is waterproof, but the control housing is not.
Adjustable Shaft – Adjusts the metal detector’s length.
Operates on two 9V alkaline batteries (not supplied).

COMPONENTS
ASSEMBLING THE METAL DETECTOR
Assembly is easy and requires no special tools. Just follow the
steps below.
1. Unscrew the knobs on the search coil and remove the knobs
and the connector. Insert the smaller shaft and align the holes
on the search coil bracket and the shaft. Push the connector
through the holes, then replace and tighten the knobs.
2. Loosen the shaft’s lock nut (attached to the handle) in the
direction of the arrow. Then insert the smaller shaft into the
larger shaft connected to the handle. Turn the shaft’s lock nut in
the direction opposite to the direction of the arrow to lock it in
place.

3. Insert the latch on top of the handle into the assembly hole at
the bottom of the control box. Slightly push the control box in
the direction of the “IN” marking on the handle to fix the latch in
place.
4. Tighten the fixing screw.
5. Insert the search coil cable plug into
the five pin jack on the back of the
control box housing.
6. Lengthen or shorten the shaft, so when you stand upright with
the metal detector in your hand, the search coil is level with and
about 0.5 to 2 inches (1 to 5 cm) above the ground. Then
tighten the lock nut.

The search coil cable plug fits into the connector only one way.
DO NOT insert the plug forcefully to avoid damaging it.
DO NOT remove the shaft lock nut. Should you remove it,
place the washer on top of the shaft connected to the handle
with the small head of the washer pointing up. Then place the
shaft lock nut on the washer and tighten it to lock it in place.
ADJUSTING THE SEARCH COIL
Loosen the knobs at the end of the search coil and adjust the search
coil to the desired angle (the search coil should be parallel with the
ground). Tighten the knobs just enough to keep the search coil from
rotating or wobbling.
INSTALLING THE BATTERIES
You need two 9 V alkaline batteries to power your metal detector.
Small head

1. If the detector is switched on, turn the power switch (on the
control box) to POWER OFF.
2. Press down the battery compartment cover and slide the cover
off in the direction of the arrow.
3. Connect the batteries to the battery connectors observing the
correct polarity. Then insert the batteries into the compartment.
4. Replace the cover.
Caution:
•Use only fresh batteries of the required size and recommended
type.
•Always remove old or weak batteries; batteries can leak
chemicals that can destroy electronic parts.
•If you do not plan to use the metal detector for a long time,
remove the batteries.
•Dispose of old batteries promptly and according to regulations.
You can extend the battery life by using headphones, which require
less power than the built-in speakers.
USING EARPHONES

Connect a pair of headphones (not supplied) to the metal detector so
you can listen to it privately. Using earphones also saves battery
power and makes it easier to identify subtle changes in the sounds
you hear, for better detection results.
To connect headphones to the metal detector, insert the 3.5 mm plug
into the EAR jack on the control box.
Note: The internal speaker is disconnected when you connect
headphones.
LISTENING SAFELY
To protect your hearing, follow the guidelines below when using
headphones.
•Set the volume to the lowest setting before you begin listening.
•After you begin listening, adjust the volume to a comfortable
level.
Headphones jack

•Do not listen at extremely high volume levels. Extended
high-volume listening can lead to permanent hearing loss.
•Once you set the volume, do not increase it. Over time, your ears
adapt to the volume level, so a volume level that does not cause
discomfort might still damage your hearing.
Traffic safety
DO NOT wear headphones while operating your metal detector near
high-traffic areas.
Even though some headphones are designed to let you hear some
outside sounds when listening at normal volume levels, they still can
present a traffic hazard.
FUNCTIONS AND INDICATORS

automatic ground balance. Rotate the control knob slowly
clockwise to eliminate different trash objects. Rotate the control
knob counter-clockwise towards the end to get to ALL METAL
mode. The ALL METAL mode also comes with automatic ground
balance. This mode used to find not only ferrous metals, but also
non-ferrous metals (see more details below).
b. SENS – Rotate the control knob counter-clockwise towards the
end to power the metal detector off. Rotate the control knob
clockwise to power the metal detector on. Continue rotating it
clockwise to get higher sensitivity.
c. VOLUME – Rotate the control knob clockwise to increase the
volume or rotate it counter clockwise to decrease the volume.
d. LOW BAT – Low battery indicator. When the LOW BAT indicator
lights up, replace the batteries at once.
e. EAR – 3.5 mm headphones jack.
f. METER – When the metal detector finds any metal target, the
meter pointer swings to the right.
TESTING AND USING THE METAL DETECTOR
This metal detector has two operating modes: ALL METAL AND
DISC.
ALL METAL – Use this mode to find all types of metals.
DISC – Use this mode to discriminate the metal type.
Set the operating mode to ALL METAL, DISC all the way
counter-clockwise, and SENS to the high position. Hold the search
coil parallel above the ground, about 0.5 to 2 inches (1 to 5 cm)

above the surface. Sweep the search coil from side to side in an arc
line of 2.75 inches (7 cm) motion.
When the metal detector detects a buried target, it sounds a tone.
Make a visual note of exact spot on the ground where the detector
beeps. Then stop the search coil directly over this point on the
ground. Move the search coil straight forward away from you and
straight back towards you a couple of times.
Slowly rotate the DISC control knob clockwise away from ALL
METAL until the unit does not sound or sounds short tones. You can
identify what kind of metal is detected according to the setting
position of DISC.
Reference for DISC setting.

Near 12:00
Nickel coin (5 cents), pull tab
Near 13:00
Zinc coin (1 cent 87 version)

Copper coin (1 cent 76 version)
When the DISC control knob is set all the way clockwise, most of
metal targets are rejected, except silver (25 cents, 50 cents and 1
dollar).
Search coil sweeping hints:
•Never sweep the search coil as if it were a pendulum. Raising the
search coil while sweeping or at the end of a sweep will cause
false readings.

•Sweep slowly, as hurrying will make you miss targets.
•Sweep the search coil from side to side in an arc line of 3 inches
(7.5 cm) motion and keep it parallel to the ground.
Factors that affect detection
Accurate detection results are difficult to achieve. It takes practice to
get the best detection results. Sometimes detecting may be
restricted by certain factors.
If there is interference from other instruments or electrical
cables, TV or radio in your search area, lower the sensitivity, or
change the current search area.
When searching in a highly mineralized area, the metal detector
will sound even if there is no metal. In this case, you can reduce
the sensitivity and increase the height between the search coil
and the ground until the false signal disappears. If necessary,
reset the DISC control knob.
When searching in a trash area, set the DISC control knob to 11
o'clock, so that the metal detector can skip most of invaluable
metal targets such as nails and small trashy iron.
Move away any metal digging tool when searching.
The sensitivity level is generally set contrary to that of
discrimination. The higher the sensitivity level is, the worse
discrimination will be. But you can reduce the sensitivity level to
achieve better discrimination.
