Precautions
To avoid possible electric shock or personal injury, and to avoid damage
to the clamp or the equipment under test, strictly adhere to the following
guidelines:
1. Inspect the instrument before using it. Do not use the device if it is
damaged.
2. Avoid storing and using the device in explosive and re hazardous
environment, high temperature, high humidity, and strong electromagnetic
radiation.
3. To avoid damage or failure of the device, it is not allowed to make any
changes at your own discretion in the electrical circuit of the device.
Features and benets
• With the RGK MD-10 metal detector, you can search for coins, relics,
jewelry, and precious metals almost anywhere. This metal detector is
versatile and easy to use.
• Two modes of operation: ALL METAL and DISC: ALL METAL (general
search) - allows you to search for all types of metal with automatic ground
balance and high sensitivity. This is the optimal mode of operation. DISC
(Recognition Search) - allows you to recognize which metal the instrument
is detecting.
• Headphone jack (not included)
• Adjustment of the sensitivity of the device and the volume of the signal in
the speaker and headphones.
• Waterproof search coil - allows you to search for metal objects in shallow
water. ATTENTION! Only the search coil is protected from water, but not
the body of the device or its other parts.
• Adjustable arm and armrest - for comfortable work with the metal detector.
Components of the device
Assembling
The assembly of the metal detector is simple and does not require any
special tools.
Follow these steps:
1. Unscrew the screw on the search coil bracket, remove the screw and nut.
Insert the bottom of the shaft into the bracket, align the holes in the search
coil bracket and the shaft. Insert the screw through the holes, tighten the nut.

2. Loosen the lock nut on the top of the rod slightly. Insert the bottom of the
rod into the top and tighten the lock nut.
3. Insert the latch on the top of the rod handle into the mounting hole on the
control box. Then, lightly press the control box in the direction of the arrow
IN on your hand to lock the latch.
4. Tighten the xing screw on the handle.

5. Wrap the search coil cable around the rod in a spiral. Insert the search coil
cable plug into the control unit connector.
6. Loosen the locking nut on the rod. Extend or shorten the bar so that when
you stand with the detector in your hand, the search coil is positioned
parallel to the ground at a distance of 1 - 5 cm. Then re-tighten the locking
nut.
The plug of the cable coming from the search coil is inserted into the
connector on the control unit in only one position. Do not push the plug,
otherwise you may damage it.
Setting up the search coil
Loosen the screw on the search coil bracket, then install the search coil at
the angle you want. The search coil must be parallel to the ground. Tighten the
screw just enough so that the coil does not wobble or sway.
Installing batteries
You will need two 9V alkaline batteries to power your instrument (not
included). Two battery compartments are located on opposite sides of the
control box.
Use only fresh batteries of the correct size and of the recommended
type. Do not dispose of used batteries with household waste. In order to
protect the environment, disposal must be carried out in accordance with local
regulations.
1. If the device is on, turn the power switch on the control panel to the
POWER OFF position.
2. Press down on the battery cover and slide it in the direction of the arrow.

3. Connect the power supply to the battery connector, observing the polarity.
Then place the battery in the compartment.
4. Close the cover.
To avoid leaks and damage to the device, always remove old or
discharged batteries. Remove the batteries if you do not plan to use the
detector for a week or more.
You can extend battery life with headphones that use less power than
built-in speakers.
Using headphones
You can connect headphones (not supplied) to the device so that only you
can hear its sounds. Using headphones improves the perception of small
changes in the audio signal and saves battery power.
To connect headphones to the detector, plug the 3.5mm headphone jack
into the EAR jack on the control panel. The built-in speaker of the detector is
disabled when headphones are connected.
Safe use of headphones
To protect your hearing, follow these guidelines:
• Set the volume to the lowest level before listening.
• When a signal sounds, adjust the volume to a comfortable level.
• Do not set the volume too high.
• Once you set the volume, do not turn it up. Over time, the ears adapt to the
volume level. For this reason, even a sound level that seems comfortable
can damage your hearing.
• Do not wear the headphones when working near high trafc areas, even if
your headphones model allows external sounds.

Control panel
DISC (Recognition Search Mode). Turn the knob clockwise from the ALL
METAL point to the right to enter DISC mode. Rotate the knob clockwise
slowly to track out false signals from (interference, debris, etc.).
Turn the knob fully counterclockwise to enter ALL METAL mode. The mode
is used to search not only for iron, but also for non-ferrous metal (see below
for details).
SENS (sensitivity). Turn the knob fully counterclockwise to turn off the
device. Turn the knob clockwise to turn on the device. Continue to turn it
clockwise to increase sensitivity.
VOLUME (volume). Rotate the control clockwise to increase the volume, or
counterclockwise to decrease it.
LOW BAT. Low battery indicator. When the LOW BAT indicator is on,
replace the batteries immediately.
EAR - 3.5mm headphone jack.
TARGET INDICATOR. Meter scale with an arrow. When the device nds
any metal object, the meter pointer turns to the right.
Working with a metal detector
The metal detector RGK MD-10 has two modes of operation: ALL METAL
and DISC. ALL METAL is used to nd any metal objects. DISC is used to
search for specic types of metal.
First, set the operation mode to ALL METAL, turn the SENS knob to
the extreme position. Then keep the search coil parallel to the ground

9
approximately 1 to 5 cm above the surface. Sweep the search coil from side to
side in a small arc.
When the detector detects a metal object, it beeps. You can mark the
exact spot on the ground where the detector beeps. Then stop the search coil
directly over this point. Move the search coil straight ahead away from you
and a couple of times back straight towards you. Meanwhile, slowly turn the
DISC knob clockwise from ALL METAL until the unit rings or beeps briey. You
can determine which metal is detected according to the position of the DISC
setting.
Useful information on the types of metals excluded from the search,
depending on the DISC setting:
All metals without exception
DISC setting Metal excluded from search
Iron
Nickel alloy coin (5 cents), beer can tongue
Zinc alloy coin (1 cent, 1987 series)
Copper coin (1 cent, 1976 series)
When the DISC knob is set clockwise until it stops, most of the metal is
discarded, except for silver (coins of 25, 50 cents and $1).
Factors that inuence search
Successful search is difcult; improvement requires constant practice.
Sometimes detection can be limited by some factors.
If there is interference in the search area from other devices and power
tools, an electric cable, TV, or radio, reduce the sensitivity or change the
current search area.

When searching in soil with a high concentration of mineral salts, the
device will beep even without detecting metal objects. In this case, you can
lower the sensitivity and increase the distance between the search coil and
ground until the false signal disappears. Restart DISC mode if necessary.
When searching in trashy ground, it is best to set DISC to 11:00 so that
the device can exclude most low-value objects such as nails and small iron
objects.
When searching, keep away from the detector any metal tools (shovels,
etc.).
The sensitivity level is usually the opposite of the recognition level. The
higher the sensitivity level, the worse the recognition will be. By lowering the
sensitivity, more effective recognition can be achieved.
Maintenance and care
Handle the device with care and attention. Dropping can damage the
boards and the case and cause the detector to malfunction.
Use the detector only under normal temperature conditions. Extreme
temperatures can shorten the life of electronic devices and damage the
detector housing.
During operation and storage, protect the device from dust and dirt, which
can cause premature wear of parts.
Keep the device clean and wipe the detector with a damp cloth from time to
time. Do not use harsh chemicals, cleaning solvents or strong detergents.
