Metal Detector HD LCD Screen Underground Metal Scanner Outdoor Gold Silver Copper Finder Item Type: Metal Detector Material: ABS Detector: 11.1V lithium battery x 1, battery capacity: 2000mAh (built in) Receiver: 11.1V lithium battery x 1, battery capacity: 2000mAh (built in) Use: In addition to military applications, it is also widely used for safety inspections, archaeological exploration, and mineral exploration Technical Parameters: 1. Search Scope: Up to 1000M 2. Detection Depth: Maximum 25M 3. Transmission Frequency: 433MHz 4. Charging Time: 5-8H Operating Instructions: 1. Hold the instrument and slowly scan in an arc, rotating yourself together. At this time, the explorer elbow should always be tightly pressed against both sides of the body, and it should be rotated approximately 40 to 60 degrees. Attention: Explorers must slowly rotate and maintain their body stability. 2. Standardize your scanning actions. Firstly, ensure that the receiving antenna is properly extended and opened. Place the receiving antenna directly in front of you and open it at a 90 degree angle to your body, without tilting to the left or right. 3. When the antenna is aligned with the target, the instrument will confirm, even if you continue to explore beyond the target. When you feel that this confirmation is effective, remember this direction. Then, move the instrument about 10 meters to the left or right and repeat the process of determining the policy mentioned earlier. Observing the determined direction this time, the intersection of the two directions is the burial direction of the target object. 4. If you feel that there is still a certain deviation in the specific direction just measured, you can determine it from another viewpoint. If the target is within about 10 meters, you should slowly and steadily follow a designated route between them. When you pass through the target and are directly above it, the antenna of the instrument will sway on both sides. At this point, the measured orientation is very accurate. (Please refer to the manual for specific operating instructions.) The product comes with a demagnetization function (as long as the probe of the receiver approaches the ferrous metal and alarms three times, demagnetization can be achieved.)
