Feature 1Large Detection Range: The metal detector has excellent sensitivity and stability with detection depth of up to 15 meters and detection range of up to 1000 meters. 2Advanced and Efficient: Strong product kernel and intelligent modular operation makes the detection powerful, convenient, efficiency and speed. 3High Detection Accuracy: This detector has a remote search system and a accurate positioning detection system, the detection method breaks through the traditional detection method. 4Microcomputer Controlled Chip: Using a microcomputer controlled chip for calibration, the self test system can quickly and easily scan and test, greatly improving efficiency and reducing the strength of testing labor. 5Practical and Economic: Equipped with the advanced detection method, the metal detector is the practical and economic metal detection instruments.Item Type: Metal DetectorMaterial: ABSWeight: Approx. 3118g/109.98ozSize:Host: 26 x11x8cm/10.2x4.3x3.1inDisplay: 9.5x5.5cm/3.7x2.2inTransmitter:11.9x8x4cm/4.7x3.1x1.6inWorking State:1. Fully charged, open the host detector, turn on the sensor button switch, press the corresponding button of the items to be detected by the sensor, adjust the host detector to adjust the depth and range search function for detection.2. In the case of handheld stable without other interference, when the detection of the specified items, the detector will sway around. Detection of larger items when the swinging action will increase in amplitude.Voltage: 100-240VRange: 1000 metersDepth: 15 metersHost Battery (shipped with built in battery): NiMH rechargeable battery, AAA, 1600MAHTransmitter Battery (shipped with built in battery): NiMH rechargeable battery, AAA, 1200MAHTransmitting Frequency: 5.6-6KHzSignal Frequency: 400-470MHzDetection Type: Gold, silver, copperCharging Time: 10-12 hoursUse: Metal finding .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Host Controller with Display1 x Receiver1 x Antenna1 x Headphones1 x Headset Box1 x Plug Adapter1 x Plastic Box1 x Instruction ManualNoteBe sure to operate strictly without interference in the wild jungle environment and maintain a good smoothness.
