Advanced Minieral Metal Detector PiLi No.2

1.Introduction
This high performance unit harnesses the power of advanced technology provide with ground balance function to measure ground mineralization and adjust itself for optimum operation, addiction the metal type mode identify the detected subject in ferrous or non-ferrous metal enhance the detection depth &accuracy effectively. AD808 is easy to operate, in order to take full advantage & functions of metal detection, please carefully read this instruction thoughtfully.
2. Application
This unit besides for the military purpose, also including applications below:
Security insepction, police quick searching, metal object detection on materail, foodstff, Metal object detection on mail, baggage, hunting buried pipe, cable, Relic& Mineral hunting, Cache treasure & mineral hunting.
3. Mineralization reaction
All soil and sand is different, containing varying amounts of naturally occurring minerals. When using old-type metal detector,as the search coil sweeps above the ground which the soil /sand with complex form, it will occurs faults signals, this phenomenon is called Mineralization Reaction. AD808 auto balance and re-calibrated function eliminate the Mineralization Reaction.
4. Features
