Feature:1. This metal detector is a gold search instrument with excellent performance. The sensitivity and stability of this detector are at the high level compared with similar products in the world.2. This detection eqquipment can identify the type of metal, allowing you to easily find metal objects that are useful to you. This is a function that other similar products do not have. With this detector, you can go to more places to start treasure hunting activities, searching for gold, silver, copper, and gems.3. This research instrument perfectly combines field archaeology and scientific theory. It has a highquality remote search system and a precise positioning detection system. It breaks through the conventional detection method. It uses a microelectronic processor to control the chip unit calibration.4. This treasure finder scans and detects easily and quickly. It greatly improves the work efficiency and reduces the working pressure of detection. It is currently an advanced, practical and economical metal detection instrument.5. This silver finder adapts intelligent modular operation. It can accurately determine the position of the buried object. Not only can you accurately know the exact location of the metal, but also you can know how many meters it is away from the ground.6. This detection eqquipment has a search system based on a microcomputer processor to control and reflect conductivity. It can also rely on the frequency regulator to identify the specific type of metal. So the detector has great practicability.Specification:Item Type: Metal DetectorMaterial: ABS PlasticSearch System: Microcomputer Processor Control and Reflection ConductivitySearch Range: Approx. 1000m/1093.6ydDetection Depth: Approx. 20m/21.9yd(For an object which is approx. 5 x 5 cm/2.0 x 2.0in, this instrument can detect at least approx. 3.5m/3.8yd. For an object which is approx. 30 x 30 cm/11.8 x 11.8in, it can detect approx. 5-8m/5.5-8.7yd. If the object which is approx. 30 x 30 cm/11.8 x 11.8in is buried for a long time, it can reach approx.12m/13.1yd. The larger the area of the object, the deeper its detection depth.)Energy: 12V 1600mAhTransmission Frequency: 5.6-6KHzSignal Frequency: 360440HzDetection Type: Gold/Silver/Copper/GemsCharging Method: The instrument has been installed with a rechargeable battery and directly connected to the charger. It can be charged, and the charging time is 10-12 hours.Plug Voltage: 100-240VInstructions/Boot Test:Turn on the switch of the host and 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:Power is the power switch button (when the instrument is not in use, the switch should not be on)Please select the metal you want to detect according to the origin of the metal you want to detect. Gold (gold)/Silver (silver)/copper (copper)/Diamonds (diamonds) are included.Use of the Host:Just turn on the power switch. Then the metal you want to detect can be detected by selecting the metal category according to the origin of the transmitter.Method of operation: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..Package List:1 x Transmitter1 x Receiver2 x Antenna1 x Power Adapter1 x Display1 x Plastic Box1 x Manual Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.The product needs to be used in an open and interference‑free environment, not indoors, indoor interference factors, such as cell phones, electromagnetic field devices, etc. will interfere with the detector signal, which will cause inaccurate product detection phenomenon.
