Feature: 1. This instrument perfectly combines field archaeology and scientific theory, has a high-quality remote search system and a precise positioning detection system, breaking through the conventional detection methods. 2. The use of microcomputer processor to control chip unit calibration and instrument self‑checking system, can easily and quickly scan and detect, which greatly improves the work efficiency of treasure hunters and reduces the labor intensity of detection. It is currently an advanced, practical and economical metal detection instrument. 3. It is a gold search instrument with excellent performance. The sensitivity and stability of this detector are the highest level of similar products in the world. In addition to the above features, another outstanding feature of this product is that it can identify the type of metal, allowing you to easily find metal objects that are useful to you. This is a function that other domestic models of similar products do not have. 4. It can accurately determine the buried position of the object and it can be located. It can also rely on the frequency regulator to identify the specific type of metal. Search system, microcomputer processor control and reflective conductivity. 5. With this detector, you can go to more places to start treasure hunting activities, searching for gold, silver, copper, and gems, which is more practical. Specification: Item Type: HandHeld Underground Metal Detector Material: ABS PlasticSearch System: Microcomputer processor control and reflection conductivity Search Range: About. 1000m/3281ft Maximum Detection Depth: Approx. 15m/49ft (For a 5 cm x 5 cm object, this instrument can detect at least 3.5 meters. For an object of 30 cm x 30 cm, it can detect 5-8 meters. If an object of this size is buried for a long time, it can reach 12 meters. The larger the area of the object, the deeper its detection depth. ) Power Supply: 12V 1000-1600mAh Transmission Frequency: 5.6-6KHZ Signal Frequency: 360-440HZ Detection Type: Gold, silver, diamond. Boot Test: Turn on the switch between the host and the search instrument, the working indicator on the search instrument will flash; when the gold gear is selected on the host, the corresponding gold indicator on the search instrument will light up, and when the other silver, gold, and gem gears on the host are selected in turn , The corresponding indicator light on the search instrument will light up. If the gear is selected on the main unit, and the corresponding indicator on the searcher is not lit, it may be that the main unit and searcher have insufficient power and need to be charged. If the above conditions are normal, the instrument is normal and can be used with confidence. Use of Transmitter: 1. Power is the power switch button (when the instrument is not in use, the switch should not be on) 2. Please select the metal you want to detect according to the origin of the metal you want to detect Gold, Silver, Copper, Diamonds. Note: you can not choose two metals at the same time, otherwise it will damage the instrument and cause no warranty. Use of The Host: Just turn on the power switch. It can be detected by selecting the metal category according to the origin of the transmitter. Operation Method: Hang the host vertically at the waist and try to keep it parallel to your legs. If you are operating the search instrument with your right hand, hang it on your right waist. If you operate it with your left hand, hang it on the left. Note: Remove metal objects such as mobile phones and keychains..
