Specification: Item Type: Metal Detector Material: Aluminum Search System: Microcomputer CPU control and reflection conductivity Size: Approx. 292 x 103mm / 11.5 x 4.1in, display screen: 95 x 55mm / 3.74 x 2.17in Search scope: Approx. 1200m/1312.3yd Detection depth: Approx. 20m/21.9yd Signal frequency: 400-470mhz Host battery (built in battery): hydrogen rechargeable battery, AAA, 1000MAH Detection types: copper, gold, silver, gemstones. Working status: 1. When fully charged, turn on the host detector, pull out the antenna, turn on the sensor switch, press the button corresponding to the item to be detected by the sensor, and then adjust the adjustment depth and range search function of the host detector to detect; 2. When the handheld device is stable without any other interference, it will sway left and right when detecting the designated detection object. When the detected object is large, the amplitude of the swaying action will increase; Power on test: Turn on the switch between the host and the searcher, and the work indicator light on the searcher will flash; When the gold gear is selected on the host, the corresponding gold indicator light on the searcher will light up. When selecting other silver, diamond, and gemstone gears on the host in sequence, the corresponding indicator light on the searcher will light up. If a gear is selected on the host but the corresponding indicator light on the searcher is not on, it is possible that the host and searcher have insufficient battery and need to be charged. If the above situation is normal, it indicates that the instrument is functioning properly and can be used with confidence.. Package List: 1 x Metal Detector With Display Screen1 x Power Plug1 x Instruction Note: 1. It is necessary to strictly operate in the jungle environment without interference and maintain great stability;2. The host and transmitter need to be turned on and off together to be used for detection;
