Feature: 1. Precise Detection: It can locate objects by accurately determining where they are buried. It can also rely on the frequency regulator to recognize the specific type of metal. 2. Sensitive and Stable: With premium remote search system and precise positioning detection system, it has excellent sensitivity and stability, simple operation and easy to use. 3. High Performance: The strongest product core, intelligent modular operation is powerful, convenient, highly efficient, easy and fast to advanced and efficient. 4. Unique Methods: Breakthrough in the traditional detection methods, the use of microcomputer controlled chip unit calibration, the instrument, self test system can be quickly and easily scanning, testing, and 5. Multifunctional: Greatly improve the work efficiency of the geocache enthusiasts, reduce the detection of labor strength. This equipment is the most advanced and practical detection method at present. Specification: Item Type: Metal Detector Search System: Microcomputer CPU Control and Reflective Conductivity Material: ABS Color: White Voltage: 100‑240V Product Size: Approx. 28x13cm / 11.0x5.1in Gross Weight: 1278g/2.8lb Search Range: 1200m Detection Depth: 25m Signal Frequency: 400‑470mhz Detector Battery (Shipped with Built in Battery): 1000MAH AAA NiMH Rechargeable Battery Detection Type: Copper, Gold, Silver, Gemstones Working Status: 1. When the main detector is fully charged, turn on the detector, extend the antennae, and turn on the sensor switch. Press the corresponding button on the sensor to detect the desired object. Adjust the main detector for depth and range search. 2. In a stable handheld condition without other interference, when the specified detection object is detected, it will swing from left to right. The swing amplitude will increase when larger objects are detected. Startup Test: Turn on the main detector and search switch. The working indicator on the search instrument will flash. When the gold gear is selected on the main detector, the corresponding gold indicator on the search instrument will lightup. When other gears such as silver is selected on the main detector, the corresponding indicator lights on the search instrument will also light up. If the gear is selected on the main detector and the corresponding indicator on the search instrument does not light up, it may be that the main detector and search instrument are low on power and need to be charged. If the above situation is normal, it means that the instrument is in good condition and can be used with confidence.. Package List: 1 x Metal Detector with Display1 x Power Plug1 x Instruction Manual3 x Accessories Note: 1. It must be operated strictly without interference in the wild jungle environment and maintain a good degree of smoothness.2. The host with the transmitter need to turn on the switch together with the use in order to detect.3. All data are measured manually, and there are certain errors in the measurement results.
