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.
The detector’s features include:
Two Operation Modes: ALL METAL, DISC
ALL METAL—lets you search for all kinds of metal with auto ground balance and high
sensitivity. It’s the best operation mode.
DISC—discriminates what kind of metal being detected.
Volume—to adjust the volume level of speaker and headphone
Earphone Jack – lets you connect stereo earphones (not supplied) to the detector in private.
View meter and Pointer – The meter pointer swings to the right if metal is found.
Water proof Search Coil – lets you search for metal objects under shallow water.
Note: The search coil is waterproof, but the control housing is not waterproof.
Adjustable Stem – lets you adjust the detector’s length for comfortable use.
Note: Your metal detector requires two 9V alkaline batteries (not supplied).
PREPARATION
ASSEMBLING THE DETECTOR
Assembling the detector is easy and requires no special tools. Just follow these steps.
1. Unscrew the knobs on the search coil and remove the knobs and
the connector. Insert the smaller stem and align the holes on the
search coil bracket and the stem. Push the connector through the
holes, then replace and tighten the knobs.
2. Loosen the stem’s (connected with the handle) lock nut in the direction of the arrow. Then
insert the smaller stem into the big stem connected with the handle. Turn the stem’s lock nut
in the reverse direction of the arrow to lock it in place.
3. Insert the latch on the top of the handle into the assembly hole on
the bottom of the control box. Then slightly push the control box in the

direction of IN on the handle to fix the latch in place.
4. Tighten the fixing screw properly.
5. Insert the search coil cable plug into the five pin jack on the front
control box’s housing.
6. Lengthen or shorten the stem, so when you stand upright with the
detector in your hand, the search coil is level with and about 1~5cm
above the ground. After that tighten the lock nut.
Caution:
The search coil cable plug fits into the connector only one way. Do not force the plug or
you could damage it.
You don’t need to disassemble the stem lock nut. In case you disassemble it carelessly,
place the washer on the top of the stem connected with the handle with the small head of
the washer upwards. Then hitch the stem lock nut on the washer then tighten it to lock it
in place.
ADJUSTING THE SEARCH COIL
Loosen the knobs at the search coil’s end, then 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 BATTERY
You need two 9V alkaline batteries to power your detector.

Cautions:
Use only fresh battery of the required size and recommended type.
1. If the detector is on, turn the power switch (on the control panel) to
POWER OFF .
2. Press on the battery compartment cover and slide the cover off in
the direction of the arrow.
3. Connect the battery with the battery connector taking care of the
polarity. Then put the battery into the compartment.
4. Replace the cover.
Cautions:
Always remove old or weak battery; battery can leak chemicals
that can destroy electronic parts.
If you do not plan to use the detector for a week or more, remove
the battery.
Dispose of old battery promptly and properly.
You can extend battery life by using earphones, which require less power than the built-in
speakers.
USING EARPHONES
You can connect a pair of stereo earphones (not supplied) to the 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 earphones to the detector, insert the earphones’ 3.5mm plug into the EAR jack on
the control panel.
Note: The detector’s internal speaker disconnects when you connect earphones.
LISTENING SAFELY
To protect your hearing, follow these guidelines when you use earphones.
Set the volume to the lowest setting before you begin listening. After you begin listening,

adjust the volume to a comfortable level.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 earphones while operating your detector near high-traffic areas.
Even though some earphones 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
1. A QUICK LOOK AT THE DETECTOR
a. DISC—Rotate the control clockwise away from ALL METAL to get DISC mode. The DISC
mode comes with auto ground balance. Rotate the control slowly and clockwise to eliminate
different trash objects.
Rotate the control counter clockwise to the end to getALL METAL
mode. All METALalso comes with auto ground balance. It’s used to
find not only ferrous metal, but also non-ferrous one (see more details
below).
b. SENS—Rotate the control counter clockwise to the end to power off
the unit.
Rotate the control clockwise to power on the unit. Continue rotating it
clockwise to get higher sensitivity.
c. VOLUME—Rotate the control clockwise to get higher level or to get
lower volume level by rotating it counter clockwise.
d. LOW BAT—Low battery indicator. When LOW BAT indicator lights,
user should replace the batteries at once.
f. EAR—It’s a 3.5mm headphone jack for connecting headphones.
g. View meter—When unit finds any metal target , the meter pointer
swings to the right.
TESTING AND USING THE DECTECTOR
The model GC1016A/MD3016A metal detector has two operation modes: ALL METAL & DISC.

All metal is used to find all kinds of metal targets. DISC is used to discriminate the metal type.
In general case, user firstly sets the operation mode to ALL METAL, DISC to counter clockwise
end, SENS to high position. Then hold the search coil parallel with the ground about 1~5cm
above the surface. Sweep the search coil from side to side in an arc line of 7cm motion.
When the detector detects a buried target, it sounds a tone. User can 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. Meantime slowly
rotate the DISC control clockwise away from ALL METAL until the unit does not sound or
sounds short tone. You can identify what kind of metal is detected according to the setting
position of DISC.
A reference for you to know what kind of metal is rejected depending on the DISC setting.
Setting of DISC Metal Rejected.
Near 11:00 Iron
Near 12:00 Nickel coin(5¢), pull tab
Near 13:00 Zinc coin(1¢ 87 version)
Near 15:00 Copper coin (1¢ 76 version)
When the DISC control is set to the clockwise end most of metal is rejected, except
silver(25¢,50¢ and 1$).
Factors That Affect The Detecting
It’s difficult to have an accurate detecting result. It needs practice to get better detection results.
Sometimes the detecting may be restricted by some factors.
If there are interference from other instruments or electrical cable or TV or radio in your searching
area, lower the sensitivity, or to change the current searching area.
When searching in highly mineralized area, the unit will sound even if there’s no metal. In this case,
you can lower the sensitivity and increase the height between the search coil and the ground until
the false signal disappears. If necessary, reset the DISC.
When searching in trash area, it’s better to set the DISC to 11:00 position, so that the unit can notch
most of invaluable metals such as nails and small
trashy iron.
Move away any metal digging tool when searching.
Sensitivity level is generally in contradiction with that of the Discrimination. The higher the
sensitivity level is, the worse discrimination will be. But you can lower the sensitivity to have better
discrimination.
