SPY20 underground metal detector using imported technology and components produced new products , compared with other similar products in china domestic , SPY20 metal detector has a great probing depth , positioning accuracy , high resolution , energy saving and environmental protection , instrumentation and long service life characteristics , maximum detection depth up to 2 meters.

SPY20 underground metal detector using advanced balance -conditioning system , the only select metal signal we need to eliminate all the debris, caused by the signal only beep only when the exploration site at the metal target , thus effectively excluded mineralization interference , and effectively improve the depth and accuracy of the instrument s probe .

SPY20 underground metal detector is mainly used in :

1. Scrap metal recycling;

2. Detect buried underground metal artifacts and treasures of gold and silver;

3. Telecommunications / electricity and other municipal departments exploration in the construction of underground lines, pipes and cables toward positioning

4. Archaeological and mining sectors , archeology , exploration the iron , prospecting research;

5. Detect metallic foreign body in the raw materials , fuel , food

6. Military demining;

7. ** Detection of the criminal investigation department search

8. Customs inspection and safety check

9. Check mail, baggage and parcel of the metal items , etc.

Instrument control key description

1. Push button

Below in the instrument has a button, and is very important in use of the instrument . The adjustment of the instrument , in the course of their work , often to press and release the button . By pressing/ release the button , the machine memory circuit automatically note of the status of the adjustment . If you forget to press/ release the button , it will affect the detection sensitivit.

2. Tuner knob

The role of the tuner is tune out the critical sound . Make the tuner clockwise rotation from the left , first opened the power switch, continue to be rotated to the right , the sound from scratch , from small to large. During detection , it should be transferred to a slight buzzing sound , the sound is very small , can barely hear , which is call critical sound . Only transferred to such faint sound , the instrument only has the highest sensitivity, If the critical sound tune too or do not bring up the sound , the instrument sensitivity will reduce.

Prior to the tune of the critical sound , be sure to press the button , after a good tune , then release the button.

Critical sound detection process gradually increases or decrease or even disappear , then press / release the button so that critical sound recovery then probe.

3. Work adjustment knob

Work adjustment knob is in line with the operating mode switch. it is around 0-10 scale. Mineralized material interference to balance operation by adjusting this knob can be excluded , and use it to identify the mode of operation , to distinguish between different types of metal.

4. Power switch

Instrument after use , set the power switch button dial to the off position , turn off the power

5. Operating mode switch

The operating mode switch has two gears : one is balanced, the other is identify.

Switch gravitropic balance file , the instrument sounds of all the metal will , but exclude the impact of the mineralization reaction . If the switch to identify the file , the instrument can distinguish between different types of metal .

6. Headphone jack and charging jack

The instrument comes standard with headphones and charger. Plug in headphones, the sound of speaker is interrupt, whe the charger is charging, the fuselage charge indicator light.
