DENVER MET-100
Instruction Manual
“CAUTION: Before starting to use the metal detector please familiarize yourself ith your
country’s local la s and regulations on here you’re allo ed to use the metal detector
and for hich findings you’re allo ed to keep and for hich findings you must turn in to
the authorities. Also take most care not to use the metal detector in any area hich might
contain dangerous items such as explosives from a ar or po ercables or gaslines or

any other dangerous items.”

The Metal Detector is a versatile and easy-to-use metal detector. It has higher
sensitivity and has the ability to differentiate the ferrous metals and nonferrous
metals. It is suitable for beginners.
Please read the manual carefully before using the unit.

Assembly
Assembly is easy and requires no special tools.
1. Align the rounded plastic part raised on the handle, with the rounded lower groove
at the control box bottom (Figure.1). Push the two parts tightly.

Figure.1
2. Align the threaded bolts at the handle bottom, with the knobs under the control
box, lock it with the bolts (Figure.2).
Figure.2
3. Turn the stem’s lock nut clockwise until it loosens, lengthen or shorten the stem so
when you stand upright with your detector in your hand, the search coil is level
with and about 1/2 inch above the ground with your arm relaxed at your side.
(Figure.3).
Figure.3
4. Loosen the knobs at the search coil’s end, then adjust the search coil to the desired
angle, let the search coil be parallel with the ground. e careful not to mistake the
location of the search coil (Figure.4).

Batteries
Please use six AA alkaline batteries.
1. Press the “key” on the battery compartment in the direction of the arrow, pull out
the battery compartment cover (Figure.5). Note: the UP words is engraved on the
battery compartment, don’t mistake the direction.
Figure.5
2. Insert six pcs AA batteries into the compartment as indicated by the polarity
symbols marked inside the compartment (Figure.6).
Figure.6
3. Close the battery compartment cover, please take care that the UP-side is up.
4. Six alkaline batteries may be used for more than 40 hours. If you do not plan to
use the detector for a long time, remove the batteries.
5. Do not mix old and new batteries.
Panel and Controller

The Panel Controller (Figure.7)
Figure.7
Power off: Power on/off power supply. The same knob with the DISC. Turn
DISCRIMINATION knob until red LED lights shortly up and then set to
NORMAL
TUNE: It is cooperated with the Red Tuning utton, and adjust balance to “0”
(yellow part of display).
Red utton: It is cooperated with TUNE to adjust balance. Keep holding red
button down and at the same time rotate TUNE knob until dial in display is set at
“0”(Yellow part of display)
DISC: Adjust DISC will help the operator to differentiate the ferrous metals and
nonferrous metals. Note: when it’s in the “NORMAL” position, the detector
sensitivity is the most strong.
Volume: Is used to adjust the loudness of the speaker.
Low attery Indication: When the red LED lights are on all the time then this
indicates the batteries are low on power. Please change to new fresh batteries
Earphone Jack: When an earphone (not included) is plugged in, the speaker will
no longer sound.
Q ick Start:
To get you master how to operate the metal detector quickly, we suggest that you
should read the quick start carefully, and practice indoor. When you are familiar with
the detector, you can hunt for the treasures just about anywhere.
1. Prepare with a sort of metal samples
an iron nail
a pull-tab and a nickel coin
a zinc coin
a silver coin
2. Lay the metal detector properly
In order to avoid the metals influence the detector, be sure to lay the the metal
6

detector properly.
Lay the search coil properly, keep the angle between search coil and aluminum
stem is about 140°.Please note not to mistake it (Figure.8)
Figure.8
Place the detector on a wooden or plastic table. Let the search coil exceeds the
table edge about more than 5 inches (15cm). (Fig.9)
Figure.9
Please take off the watch, ring or other metal objects on your hand or arm.
Keep the detector away from the wall, floor and other metal objects.
e sure to keep the detector away from the light, TV, computer and mobile
telephone, which can cause electro-magnetic interference.
3. Turn on
Turn on the power supply. Turn DISC knob power on until red LED light shortly
up and then set to NORMAL.
4. Adjust balance.
Keep holding red button down and at the same time rotate TUNE knob until dial
in display is set at “0” (Yellow part of display). Release the Red utton. The
meter pointer should maintain near the “0”, now the balance has been adjusted.
The detector is in the sensitive detection state. (Fig.10).

Figure.10
Adjust the Volume potentiometer, let you can hear the light hum tone, don’t
adjust it too loud.
Once you adjust the “DISC” button, you should adjust the balance over again.
In general, you should only press the Red utton to let the detector return to
the balance state.
During operating, if there is no metals around detector, while the meter pointer
deviates from the “0”position, you should also adjust the balance over again.
5. Test samples, discriminate ferrous metal and nonferrous metal.
Set the “DISC” knob to “NORMAL”. Adjust the balance to let the meter
pointer points “0”. Adjust “VOLUME” to let the detector sound a light hum
tone.
Let the metal samples approach the search coil in turn, pay attention to the
meter pointer swing and the voice change.
When the iron nail approach the search coil slowly, the meter pointer will
deflect to the left, and the sound will turn light. When the iron nail is more
closer to the search coil, the meter pointer will deflect to the left more and the
sound turns more lighter, until it disappears. (Figure.11)

Figure.11
Let other nonferrous metals approach the search coil, the meter pointer will
deflect to the right, and the sound will turn louder. (Figure.12)
Figure.12
6. Discriminate silver
Set the “DISC” knob to “MAX”. Adjust the balance to let the meter pointer
points “0”and the detector sound a light hum tone.
Let the silver coin approach the search coil slowly, the meter pointer will
deflect to the right, and the sound will turn loud. (Figure.13)
Figure.13
Let other metal samples approach the search coil slowly, the meter pointer will
deflect to the left, and the sound will turn light. (Figure.14)

Figure.14
7. Discriminate different metals approximately
We take nickel coin and pull tab as an example to explain the approximate
discrimination method.
Set the DISCRIMINATION to about “12:00” position (Figure.15). Adjust the
balance to let the detector sound a hum tone, and the show is “0”
Figure.15
Let the iron nail, nickel coin and pull tab approach the search coil slowly, the
sound tones light, and the meter pointer deflects to the left.
Let the higher conductivity objects, such as zinc coin and silver coin approach
the search coil slowly, the sound tones louder, and the meter pointer deflect to
the right.
The “12:00” position is the nickel coin and pull tab discrimination position.
Rotate the “DISC” knob from “NORMAL” to “MAX”, you can find the
different metals discrimination position. The metals with low conductivity,
discrimination position is anear the left side, and the iron discrimination
position is in the most left (NORMAL).The metals with high conductivity,
discrimination position is anear the right side, and the silver discrimination
position is in the most right (MAX).
8. Explanation
Discriminating metals is based on the change of sound and meter pointer
direction. The discrimination is preliminary, and it’s only a reference for
treasure hunters.
When the DISC is in the “NORMAL” position, the detector sensitivity is the
most.
9. Operation outdoors
y learning, you have learned how to operate the detector. In the wild, as the soil,
sea sand, ores and other environmental impacts and the interference of
electromagnetic fields, the detector sensitivity and discrimination location will be
changed. You should practice time after time and accumulate the experience to
master the skill of detect gradually, and you will taste the joy of treasure-hunting.
Field Operation
Metal detector is used outdoors. There is too much metals indoors, and also all kinds
