underground metal detector mine detector epx7500,deep depth long range metal detector epx-7500,50m depth and 1000m range function: (1) we add a function of indicator lights. these indicator lights show 20 different distances between the user with a receiver and the tramitter. (2) most common frequencies are gold, silver, copper, placer gold, tin, aluminum and jewel. (3) detecting range: 100-1000m (4) detecting depth: 5-50m (5) after tracking target, you will have some idea of the identification and the exact pinpoint. (6) the face (front) of the tramitter has six led&quo;s (channel indicator lights) across the top; each is labeled for a particular element. components: (1) a black case with aluminum trim, a handle and two locks; (2) external battery port; (3) the belt receiver; (4) receiving rods; (5) battery charger; (6) antenna; (7) marker flags; (8) operato manual and cd specification: (1) max detection: 5-50m (2) detect range: 100-1000m (3) rechargeable battery: continuous working 48 hou (4) power: 850ma (5) frequency: 433mhz+/-150khz (6) inner storage: eeprom 16k*8bit (7) voltage: 9~12vdc (8) temperature range: -40°c~85°c (9) operating humidity: 0~95% (non-condeing) (10) ultrasonic frequency: 400-3000mhz+/-150khz (11) weight: 14lbs package: (1) size/unit: 45*32*20cm (2) weight/unit: 6kg (3) qty./ctn: 1unit (4) size/ctn: 46*34*24 (5) g.w./ctn: 7.5kg 本产品的加工定制是是，类型是金属探测器，品牌是oem，型号是epx-7500，重量是7.5（kg），用途是矿物金属探测
