Feature:1. Easy Scanning: The use of microelectronic processors to control chip unit calibration and instrument self inspection systems can facilitate and quickly scan and test, improve the work efficiency and save your labor.2. High in Accuracy: The detector has high sensitivity and stability, can identify different types of metals, and can easily find useful metal objects for you.3. Quick Detection: Accurately determine where the object is buried and locate it. Specific types of metals can be identified through frequency regulators. Equipped with remote search system and precise position detection system.4. Detected Objects: The metal finder can quickly detect gold, silver, copper, conventional metals as well as stones such as emeralds, opals, etc. Can also be widely used for safety inspections, archaeological exploration, and mineral exploration.5. Convenient Carry: Mainly made of premium aluminum alloy material, the metal detector is very convenient to carry for indoor and outdoor scanning.Specification:Item Type: Metal DetectorMaterial: ABS, sponge coating, aluminum alloyDetector Battery: Built in rechargeable nickel chromium battery. Receiver Battery: Built in rechargeable nickel chromium battery. Use: Widely used for safety inspections, archaeological exploration, mineral exploration, etc. Detected Objects: For gold, silver, copper, conventional metals such as palladium, platinum,and stones such as emeralds, etc. Search Range: Approx. 1000m / 3280.84ft. Detection Depth: Approx. 15m / 49.21ft, maximum. Transmission Frequency: 5.6-6KHzSignal Frequency: 433HzHow to Use: 1. Hold the instrument and slowly scan in an arc, swing yourself together. At this point, the your elbow should always be tightly pressed against both sides of the body, and it should be swang approximately 40 to 60 degrees. Note that you must slowly swing and maintain stable body. 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 unfold 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 way 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, and 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. .Package List:1 x Metal Detector1 x Receiver1 x Adapter1 x Headphone2 x Signal Rod1 x User Manual1 x Storage Box1 x StickerNote:The product needs to be used in an open and undisturbed environment, and cannot be used indoors.
