ClonePI-W is a modern microprocessor-based universal pulse metal detector. The device is designed to search for metal objects in the ground, sand, walls, dense grass, etc. Using the device in a set with interchangeable sensors of different sizes allows you to solve a wide range of search tasks in treasure hunting, construction, when searching for lost things and in other specific areas of human activity. Main technical characteristics The maximum depth of detection of objects (in the air): With a ring sensor (diameter 19cm) Coin with a diameter of 25mm - up to 30cm; Helmet - up to 60cm; The maximum depth of up to 150cm; With depth loop probe (1,2х1,2m)  Helmet - up to 140cm; Steel barrel 200l - up to 200cm; Maximum depth - up to 300cm. Indication: Visual LED; Audio multitonal; Search mode static; Continuous operation time with a fully charged battery up to 15 hours. Operating conditions Air temperature -10...+50ºС. Atmospheric pressure 710...800 mm Hg. Relative humidity up to 95% at temperature +25ºС. It is strictly prohibited to operate the unit with the cover removed or with damaged insulation of the sensor cable because of the risk of electric shock. The principle of operation of the ClonePI-W pulse metal detector is based on excitation of pulse eddy currents in the metal object and measurement of the secondary electromagnetic field which induces these currents. Using the built-in microprocessor, the device analyzes this over-radiated signal and produces the corresponding indication of the detected object.
