Specification: Item Type: Metal Hunter Machine Material: ABS Gross Weight: 2063g/72.8oz Search System: Microcomputer CPU control and reflected conductivity Voltage: 100-240V Product size: 31x22x9CM/12.2x8.7x3.5in Search Range: 1000m Detection Depth: 30m Host Battery: NiMH rechargeable battery, AAA, 1000MAH, shipped with built in battery Transmission Frequency: 5.6-6KHZ Signal Frequency: 400-470mhz Detection Type: Gold, silver, diamond. Working Status: 1. When fully charged, turn on the host detector, open the antenna, turn on the sensor switch, press the button corresponding to the item that the sensor needs to detect, and adjust the host detector to adjust the depth and range search function to detect; 2. In the case of steady hand holding and no other interference, it will sway from side to side when detecting the designated object, and the amplitude of the swing will increase when the detected object is larger; Boot test: 1. Turn on the switch between the host and the searcher, the work indicator on the searcher will flash; when the gold gear is selected on the host, the corresponding gold indicator on the searcher will be on, and when the other silver, diamond and gem gears on the host are selected in turn , the corresponding indicator on the searcher will light up. 2. If the gear selection on the host appears, but the corresponding indicator light on the searcher is not on, the power of the host and searcher may be insufficient and need to be charged. 3. If the above conditions are normal, the instrument is normal and can be used with confidence..
