Feature: 1. High Sensitivity: This metal detector has high sensitivity and stability, it can recognize different types of metal and can easily find the metal objects that are useful to you. 2. Excellent ABS Material: This metal detector is made of excellent ABS material, which is strong and wear resistant, not easy to be damaged and has a long service life. 3. Microelectronic Processor: This metal detector utilizes a microelectronic processor for controlling the chip unit calibration and instrument self testing system, which allows for easy and fast scanning and testing, increasing the efficiency of work. 4. Accurate Location: This metal detector can determine exactly where an object is buried, and can identify specific types of metal with a frequency modulator, and features a remote search system and an accurate location detection system. 5. Wide Application: This metal detector has a wide range of applications and is widely used for security checks, archaeological treasures and more. Specification: Item Type: Metal Detector Material: ABS Detector: 12.6V Lithium battery x 1, Battery Capacity: 2000mAh??Shipped With Built In Battery) Receiver: 12.6V Lithium Battery x 1, Battery Capacity: 2000mAh ( Shipped With Built In Battery ) Power Adapter Voltage: AC 100-240V Uses: It is widely used in addition to military applications: security checks, archaeological treasure hunting, prospecting. Technical Parameters: Search Range: Maximum Approx. 1500m/4921.3ft Detection Depth: Maximum Approx. 30m/98.4ft Transmission Frequency: 433MHz How To Use: 1. Hold the instrument, slowly scanning in an arc, together with the rotation of your own. At this time, the explorer's elbow should always be tightly attached to the sides of the body, about 40 degrees to 60 degrees can turn. Prospector must slowly rotate, and to adhere to the body's stability. 2. Standardize your scanning action. First of all, let the receiving antenna correctly stretch open after. Make the receiving antenna in front of you, and your body into 90 degrees open, not to the left and right sides of the deflection. 3. When the antenna is aligned with the target object, the instrument will be determined, although you continue to explore across the target. When you feel that this determination is valid, you remember the direction. Then, move the instrument about 10 meters to the left or right and repeat the process of determining the approach as described above. Observe the direction of this determination. The intersection of the two directions is the buried position of the object. 4. If you feel that the exact position you have just measured is still off, you can determine it from another point of view. If the object is within 10 meters, you should walk slowly and smoothly along one of the routes. When you pass the object and are directly above it, the antenna of the instrument will be shaken on both sides. At this point, the measured position will be very accurate. (Please refer to the instruction manual for specific operation instructions.) The metal detector comes with a demagnetization function (as long as the probe of the receiver is close to the ferrous metal, the alarm three times, can be demagnetized)..
