Feature: 1. High Accuracy Detection: Metal detector accurately detects buried objects, pinpointing their location. It also distinguishes between metal types through its adjustable frequency regulator. 2. Wide Application: Metal detector finder has excellent sensitivity and stability, simple operation, can be used to detect copper, gold, silver, precious stones. 3. Powerful Search System: With a remote search system and a precise positioning detection system, using a microcomputer control chip unit calibration, the detector device can scan and detect metals quickly and easily. 4. Advanced Range and Depth: With a scanning range of up to 1200m and a detection depth of 20m, our metal finder covers a wide area and penetrates deep into the ground. 5. Improve Efficiency: Metal detectors greatly improve the work efficiency of underground treasure lovers, reduce the detection labor intensity, is the most advanced and practical detection method. Specification: Item Type: Metal Detector Material: Aluminum Product Dimension: Approx. 292 x 103mm / 11.5 x 4.1in, Display Screen: Approx. 95 x 55mm / 3.7 x 2.2in Searching Range: Approx. 1200m / 3937ftDetection Depth: Approx. 20m / 65.6ftSignal Frequency: 400 - 470mhz Host Battery (shipped with built-in battery): Nickel-metal hydride rechargeable battery, AAA, 1000mAh Detection Type: Copper, gold, silver, jewel Working Status: 1. Charge the host and turn the host detector on, pull the antenna out, turn on the sensor switch, and press the button corresponding to the item that needs to be detected. Then adjust the depth and range search function of the host detector to detect. 2. Hold the equipment balanced without any interference. When a specified detected item is detected, it will shake from side to side. If the detected item is larger, the amplitude of the shaking action will increase. Start-up Test: Turn on the host and the receiver, the work indicator will blink on the receiver. When the gold gear is selected on the host, the corresponding gold indicator on the receiver lights up. When the silver, diamond, and gem gears on the host are selected in turn, the corresponding indicator lights up on the receiver. If the gear is selected on the host, but the corresponding indicator on the receiver does not light up, it is possible that the host and the receiver are running out of power and need to be recharged. If the above situation is normal, it means that the instrument is working properly and can be used with confidence. Weight: Approx. 1406.00g / 49.6oz.
