Remote Metal Detector High Accuracy Handheld Metal Finder Jewellery Search Locator Item Type: Metal Finder Material: ABS, Sponge Coating, Aluminum Alloy Detector Battery: 1600mAh Rechargeable Nickel Cadmium Battery (built in battery) Receiver Battery: 1000mAh Rechargeable Nickel Cadmium Battery (built in battery) Application: Widely used in military, security inspections, archaeological exploration, and mineral exploration Detected Objects: Gold, silver, copper, conventional valuable metals (Pd, Pt), gem (diamond, emeralds, etc.) Search Range: Approx. 1500 meter / 4921.3ft Detection Depth: Approx. 25 meter / 82ft Transmission Frequency: 5.6-6KHz Signal Frequency: 360-440HzHow e: 1. Hold the device and slowly scan in an arc, rotating yourself together. At this point, the explorer elbow should always be tightly pressed against both sides of the body, and it should be rotated approximately 40 to 60 degrees. 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 antenna directly in front of you and open it at a 90° angle to your body, without tilting to the left or right. 3. When the antenna is aligned with the target, the device will confirm, even if you continue to explore beyond the target. When you feel that this confirmation is effective, remember this direction. Then, move 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 both 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 device will sway on both sides. At this point, the measured orientation is very accurate. (Please refer to the manual for specific operation instructions) The product comes with a demagnetization function (as long as the probe of the receiver is close to the iron metal and an alarm is given three times, demagnetization can be achieved)
