Product Introduction
SLKD-M801 metal detector is the patented product which developed independently
by Hunan Puqi Geologic Exploration Equipment Institute, patent number:
201230519707.5 . SLKD-M801 metal pipeline detector own better performance, more
accurate.

Introduction of Operating Button
1. Main Switch
The instrument power switch
2. GBAL
There exist trace metals more or less in the soil and rock or the mine area. Detector
probe generates a signal when close to the ground, forming a mineralization reaction
interference. In the process of searching along the ground, change the distance of the
probe with the ground caused by the critical voice suddenly large and small changes ,
people can not tell the end is a signal or a signal metal mineralization reaction . To
solve this problem , this instrument is designed to ground balance line, to minimize
the impact of mineralization reaction .

This knob to adjust the instrument during use according to the actual situation, the
reactions to adjust the instrument so that the instrument is in top working condition.
This is what we want to be transferred to the balance point, the signal source is
detected only when the instrument is issued until the valid alarm.
3. TUNE
Tune knob is in collaboration with various operating knob debugging instrument used
to coordinate the arrow keys when using the built- balance each knob are likely to use
this knob to adjust the fit of the instrument, it is ultimately the instrument to achieve
the best working condition.
4. DISC
DISC knob is to adjust the critical tone sound. Only when the signal is detected the
instrument will send out alarm sound. The clockwise rotation of the knob from the
left , the sound from nothing to have , from small to large. In the detection, should be
transferred to one slight hum, the sound is very small, as long as can barely hear on
the line, this is the critical voice. Only the faint sound transferred to this situation, the
instrument has the highest sensitivity signal reception. If too much of the critical tone
or no sound out of tune the instrument signal sensitivity will be reduced .
Before the critical tone sound, be sure to press the reset button, after a good tune and
then release the button. If in the detection process, the critical sound gradually
increase or decrease or even disappear, just press the reset button so that the sound of
recovery, then proceed detecting.
After using the instrument, the tuner is rotated counterclockwise twist to the left end
and turn off the power, please do not make the instrument power vacant on.
5. SENS
The SENS knob controls the sensitivity of the instrument. The knob counter-
clockwise twist to the end, the sensitivity of the instrument will be reduced to
minimum, small depth detection; when screwed to the right end, the highest
sensitivity, the maximum depth of detection .
We always want to explore deeper, but do not ignore the impact of mine reaction. In
large of mineralization reaction section, increased sensitivity can cause false signals
after the instrument sound chaos everywhere, but explore anything. When this
happens, it should be appropriate to reduce the sensitivity to reduce the effect of
complex formation. But there is no debris in the soil evenly place, can be transferred
to the highest sensitivity, when the instrument reaches the maximum detection depth.

Note : Manipulator must press reset button after adjusting SENS knob every time.
6. Phone Out
SLKD-M801 instrument can be equipped with headphones. After plug in headphones,
external speakers sound interruption, the operator can hear the sound from the headset,
so that operating in a noisy or night environment. Use the headset to get battery
saving, meanwhile it is easy to determine the sound subtle changes, so as to achieve
better detection results. The headset is connected to the detector, we need to plug the
headset into the host back-end headphone jack.
Introduction of Signaling Display Device
1. Power LED
This light up after starting up, it indicates that the instrument is in a state of power-on.
2. Low Voltage LED
When this light is on, the meter voltage is insufficient , the instrument will not work
normally, you need to replace or recharge.

7
3. Micro Signal indicator
When this light display, the instrument is sensitive to detect small objects, on behalf
of a small object buried deeper.
4. Signal Indicator
When an object is detected or sensed electromagnetic signal source, the intensity of
this light display will represent the size of the object to be detected or buried depth.
5. RESET Button
There are two buttons at the bottom of indicating meter - Reset Button , also known as zero button.
If you hold the button down , the instrument will always be in reset state , will not be reacted for
any signal.
Before adjusting any knob on the instrument, should first hold the reset button down, after finish
adjusting, release the button. Indicating meter resetting occurs deviation along with changes in the
environment, press , release the button , the instrument will reset through pressing and releasing
the button,therefore, the entire detection process should often press the button to reset.
After press and release the button , memory circuits inside the machine will make a note to adjust
the working status, if you forget press and release the button, it is bound to affect the normal work
and detecting depth of the machine.
Note: You need to warm-up time of about 1-3 minutes once machine on . If the instrument not
reset, press the button and release , instrument will be in the reset state.

How to Install
1. Connecting PVC bar with detection disk. First remove detection disk connecting
rod and the nut, and then use connecting rod and nut fix PVC bar on the detection disk,
as showed in Figure 1.

9
2. Connect the host machine with detection disk using connecting device.

10
3. Insert detection disk plug into detection disk interface of host machine.
4. Place 8 AA battery into the battery box , turn on the power switch, you can begin
to detect preheating .
Kindly Reminder: Please use the rechargeable AA battery to avoid the environmental
pollution.
