Feature:1. Specific Function: The metal detector can accurately determine the buried position of the object and can be localized. It can also rely on the frequency regulator to recognize the specific type of metal.2. High Performance: This metal detector has a search range of 800m/875yd and a detection depth of about 12m/39.4ft, 12V 1600mAh energy source, 5.66KHz transmitting frequency, 360440Hz signal frequency.3. Efficient: Handheld metal detector with microcomputer processor control and reflective conductivity search system, intelligent modular operation, powerful, efficient and convenient, easy to use.4. Detection Depth: For a 5x5cm object, it can detect at least 3.5m/11.5ft. For a 30x30cm object, it can detect 58m / 16.426.2ft, and if buried for a long time, it can up to 12m/39.4ft. The larger the area of the object, the deeper the depth of detection.5. Easy To Use: Power is the power on off button (do not leave the switch on when the detector is not in use). Choose the metal you want to detect (gold, silver, copper, jade).6. Indicator Light Design: Host and finder switch, the working indicator light on the finder will flash, when selecting the corresponding metal gear, the corresponding indicator light on the finder will light.Specification:Item Type: Metal Detector HostMaterial: MetalBattery Type: AAA (Built in)Battery Type: NI MH batteryBattery Quantity: 6pcsBattery Capacity: 900mAh.Package List:1 x English Manual 6 x Signal Frame 1 x Charger1 xMetal Detector HostNote:1. Can not choose two kinds of metal detection at the same time, otherwise it will cause damage to the device.2. If the gear is selected on the host and the corresponding indicator light on the finder is not lit, the host and finder may be low on power and need to be charged.3. Because the instrument's handle rotates freely, wind can interfere with the detector. Use in windy conditions will cause some interference.4. You must keep the instrument in front of your body and the receiving antenna has enough room to spread out and the antenna is tilted slightly downward from horizontal. This angle is probably between 7 and 10 degrees.5. Always rotate the detector slowly and keep your body steady. Standardize your scanning motion. First, allow the receiving antenna to extend back properly. Keep the receiving antenna directly in front of you, at 90 degrees to your body, and not deflected to the left or right. When the antenna is aligned with the target, the instrument will lock on, even though you continue to detect across the target. When you feel that this lock is effective, you memorize the direction. Then, move the instrument about 10 meters to the left or right and repeat the process of locking on to the target as just described. Observe the locking direction this time. The intersection of the two directions is the buried position of the target. If you feel that the specific position measured just now still has some deviation, you can lock from another angle. If the target is within 10 meters or less, walk slowly and smoothly along one of the routes. When you pass the target and are directly above it, the antenna of the instrument will swing both ways. The measured position is then very accurate.
