With high sensitivity and stability, it can identify and find different types of metals Made of ABS material, which is lightweight, strong, and durable for long-lasting It can fast and accurate positioning and identification of metal types The microelectronic processor can scan and test easily and quickly It is widely used in security inspections, archaeological treasures, etc. Specification: Material: ABS Battery Type: 9.6V, 800mAh Rechargeable Lithium Ion Battery (Included) Power Adapter Voltage: AC 100-240V Search Range: Approx. 1-99m/3.3-324.8ft Detection Depth: Approx. 16m/52.5ft Transmission Frequency: 5.6-6KHz Signal Frequency: 360-440Hz Charging Time: 5-8h Application: It is widely used in security inspections, archaeological treasure hunting, and mineral prospecting How to Use: 1. Hold the instrument, scan in an arc slowly, and rotate yourself together. At this time, the elbows should always be tightly attached to the sides of the body, and it is enough to rotate about 40-60°. The prospector must rotate slowly and maintain a steady body. 2. Standardize your scanning actions. First, let the receiving antenna be correctly extended after opening. Make the receiving antenna directly in front of you, open at 90° to your body, and not deflect to the left and right. 3. When the antenna is aligned with the target, the instrument will confirm it, even if you the target and continue to explore. When you feel that this determination is effective, remember this direction. Then, move the instrument to the left or right about 10m, and repeat the process of determining the policy just mentioned. Observing the determined direction this time, the intersection of the two directions is the buried position of the target. 4. If you feel that there is a certain deviation in the specific position that has just been measured, you can determine it from another point of view. If the target is within 10m, slowly and steadily follow a prescribed route. When you pass the target and you are directly above it, the antenna of the instrument will shake on both sides. The position measured at this time is very accurate. (Please refer to the manual for specific operation instructions). The product has its own degaussing function (as long as the receiver probe is close to the ferrous metal, alarm 3 times, and can be degaussed) Note: It can scan gold, silver, copper, and gems with high metal content. It cannot detect other metals.
