Genuine Metal Detector Underground Metal Detector with 1.5m Detection Depth SMART
1, applicable scope
This product in addition to the application of the military, also applies to the following fields:
* * criminal Department quick search
Detection of raw materials, fuel, metal impurities in food
Metal objects check mail, parcel of
Inspection of underground pipes, cables
Found buried in the acquisition of the treasures of gold and silver and metal mineral scrap metal
2, the mineralization reaction
Because of a variety of mineral soil can make the instrument signal, in the use of the old underground metal detectors, signal changes with distance detector and the ground has changed, if the probe ground surfaces, signal change is bigger, the soil structure complex, signal caused by even the soil bigger than the metal signal, this phenomenon is called “mineralization reaction”.
3, product features

Automatic regulating function
Manual adjustment to eliminate the mineralization reaction
The speaker voice prompt
Battery low indicator
LED luminous function
The induction coil short-term automatic alarm (when the loose connection cable will automatically alarm)
4, the product specifications
The maximum detection depth: 1.5 meters (50 cm x 50 cm x 1.2 cm aluminum)
Detection methods: balance detection / recognition detection
The main vibration frequency: 4.19MHZ
The signal frequency: 7.1KHZ
Power supply: DC 3.7V (rechargeable)

Method of metal detection: This machine operation as a sapper detection, probe the ground 10-15 cm distance detection, move in parallel along the ground, in order to avoid the actual detecting depth decreased.
(a) adjusting balance
The instrument has two kinds of balancing method
1, automatic adjusting balance:
Automatically adjust the balance model is also starting operation. Use this mode to achieve balance, left a display on LCD
A fan-shaped pattern, “sensitivity” and the four point star pattern.
2, manual balancing method
Manual balancing mode can be divided into the following two:
In a, has reached an equilibrium state, press the “balance” button, immediately release the, time is not more than 2S, the
Type equivalent to automatically adjust the balance, but also the same Yu Gang boot operation.
In B, has reached an equilibrium state, press the “balance” button, the time should be greater than 2S, LCD on the left
A fan-shaped stripe. This method is often used in the detection process, the balancing method, is very simple
Single, and can improve the accuracy of detecting metal.
(two) to eliminate the mineralization reaction
The mineralization reaction can be eliminated by two methods of manual and automation:
1, automatic, should first turn off the power switch of the instrument, then the “knob” rotate left a little, and then boot, to reach equilibrium, the probe near the ground, 10-15 cm from the ground. If the fan icon LCD increase or more than 6, according to the method of regulating, until transferred to the probe up and down, LCD Fan icon on the display of 2 or 4, automatic balance is finished.
2, used manually, press the “balance” button is not put, time is greater than 2S, while the “knob” to the left turn, loosen the “balance” button to return to the equilibrium state, the probe near the ground 10-15 cm test. If fan icon LCD increase or more than 6, according to the program to be adjusted, until you reach the same effect with automatic adjustment, manual adjustment is completed, at this time, the earth be eliminated basically mineralization reaction.
3, pay attention to: manually adjusted prior to hold down the “balance” button, then loosen the adjustment.
(three) identify / remove metal regulation
According to the specific circumstances to adjust the “knob” to exclude those who do not need metal target detection, such as many places in a nail, nails everywhere signal issued, the speaker will gradually increase the voice, LCD also has the corresponding display makes the detection work is not convenient, encountered such a situation, you can put in advance a nail on the floor above, let the probe nails, if the instrument’s sound increase, fan-shaped icon on the LCD increase, can press the “balance” button, the time is more than 2S, while the “knob” to the left a bit. To return to the equilibrium state, then the probe moved to the nails to try again, until the LCD sector icon display 2 or 4, the recognition / exclude metal regulation is good. Sometimes, need several adjustments “knob” direction, in order to achieve the best effect, which requires long-term accumulation of exploration experience, in order to better operation and use of the instrument.
Three, the night of lights and LCD backlight
1, when you need to use the ground lighting, can speak lamp switch to the “lights” position.
2, in the dark environment, according to a “backlight” button to open the backlight lamp switch, convenient operation, press again this switch, the backlight is off.
Four, when the LCD battery symbol “” appears to be empty, should be timely replacement of the battery, so as not to reduce the sensitivity of detection and accuracy.
Matters needing attention:
One, if the device is not working properly, sound can’t be decreased after increasing, the battery power shortage, should replace the new battery.
Two, don’t press the metal in the above button should press the button in the absence of metal surface, can not hold the button does not discharge detection
Three, if the instrument can’t keep the “critical sound”, prove the instrument failure, should be sent to the factory for repairs.
