1、The gold and silver dollar searcher with excellent performance is built with imported technology. 2、Easy to use, you can directly select the type of metal you want to detect. 3、The positioning range is more accurate, and the positioning attributes are more accurate. 4、Rechargeable metal detector, the machine set cotains a box, easy to carry and use. 5、It is widely used in military applications, security inspections, archaeological treasure hunting, and mining prospecting. Item Type: Metal Detector Material: Aluminum Alloy Color: Yellow Built-In Lithium Battery: Rechargeable (lithium ion battery, 9.6V, 800mAh) Search Range: 1-99M Detection Depth: 16M Transmission Frequency: 5.6-6KHz Signal Frequency: 360-440Hz Charging Time: 5-8H Metals that can be scanned include gold, silver, copper, and gems with high metal content. It cannot detect other metals. The product has its own degaussing function (as long as the probe of the receiver is close to the ferrous metal and the alarm is three times, it can be degaussed) Uses: In addition to military applications, it is also widely used in security inspections, archaeological treasure hunting, and mineral prospecting. How to Use: 1. Hold the instrument, scan in an arc very slowly, and rotate yourself together. At this time, the prospector's elbows should always be tightly attached to the sides of the body, and it is enough to rotate about 40 to 60 degrees. Note: The prospector must rotate slowly and maintain a steady body. 2. Standardize your scanning actions. First of all, let the receiving antenna be properly extended after opening. Make the receiving antenna directly in front of you, open at 90 degrees 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 cross the target and continue to explore. When you feel that this determination is effective, you keep this direction in mind. Then, move the instrument to the left or right about 10 meters, 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 10 meters, you will 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.
