Feature:1. WIDE RANGE: The metal detector kit features a remote search system and an accurate position detection system. Moreover, the detection range can reach 1000meter, and the underground detection depth can reach 15meter2. HIGH PERFORMANCE: The underground metal detector is made of excellent aluminum alloy material, durable, safe, easy to use, with long life3. DURABLE AND PRACTICAL: Metal detector built in 1600mAh large capacity rechargeable battery, lasting life. Signal frequency 360440HZ, you can explore more places4. PROFESSIONAL AND EFFICIENT: The micro electronic processor control the chip unit calibration and instrument self test system, which can easily and quickly scan and test, improve the work efficiency of treasure hunters and reduce the labor strength of testing5. SENSITIVE AND ACCURATE: The metal detector pointer has high sensitivity and stability, and can rely on the frequency regulator to identify the specific type of metal(gold, silver, copper, diamond(precious stone)), so that you can easily find the metal items that are useful to you, and accurately determine the location of the object6. APPLICABLE SCENARIO: Underground metal scanner can be located, suitable for finding treasure, looking for gold, silver, copper and precious stonesSpecification:Item Type: Metal DetectorSearch Range: Approx. 1000meter / 3280.8ftDetection Depth: Approx. 15meter / 49.2ftDetector: 1 x 12V Lithium Battery, Battery Capacity: 1600mAhReceiver: 1 x 12V Lithium Battery, Battery Capacity: 1600mAhTransmission Frequency: 5.6~6KHZSignal Frequency: 360-440HZCharging Time: 5-8HDetection Depth: This instrument can detect at least 3.5meters for an object measuring 5cm x 5cm.For an object of 30cm x 30cm, can detect 5-8 meters, and if the object of this size is buried for a long time, can reach 12 meters.The larger the area of the object, the deeper the detection depth will be.Features: Can accurately determine the buried location of the object, can be located.The frequency regulator can also be used to identify the specific type of metal.How to Use:Stand in a comfortable position on the ground, holding the instrument in your hands, with your elbows firmly against your sides. Note: You must have this instrument in front of your body, allow enough room for the receiving antenna to unfold, and tilt the antenna slightly downward from the horizontal line. The angle is somewhere between 7 and 10 degrees.1. Hold the instrument and scan it very slowly in an arc, rotating yourself together. At this time, the prospector should always keep his elbows firmly against the sides of the body, and turn about 40 to 60 degrees. Note: The prospector must rotate slowly and stick to a steady body.2. Standardize your scanning actions. First, after the receiving antenna is properly extended and opened. Keep the receiving antenna directly in front of you, open at 90 degrees from your body, and cannot be deflected to the left or right.3. When the line is aligned with the target object, the instrument will determine the location, although you continue to explore across the target. When you feel that this determination is valid, you remember this direction. Then, move the instrument about 10 meters to the left or right, and repeat the process of determining the policy described earlier. Observe this time to determine the direction, the intersection of the two directions is the buried orientation of the object.4. If you feel that the specific orientation you just measured has a certain offset, you can determine it from another viewpoint. If the object is within 10 meters or so, you walk slowly and smoothly along one of the designated routes. When you pass the object and are directly above it, the antenna of the instrument wobbles on both sides. Now the azimuth is very accurate..Package List:1 x Detector1 x Receiver1 x Power Adapter6 x Antenna1 x User Manual1 x Black Storage BoxNote:1. Do not disassemble or modify the instrument.2. Try to avoid mobile phones or other metals near the instrument during operation.3. Please use this instrument in the temperature of 040 and 10% 30% humidity environment.4. The use of wires, needles and other metal objects to short circuit the battery, do not put the battery with the necklace and other metal objects together, otherwise will cause electrical leakage, overheating, burst and fire.5. Do not charge continuously for 24 hours. Use AC. Note: The new battery will only be effective if goes through two or three cycles of full charge and discharge.6. Keep away dust and dirt, which can cause corrosion and wear of parts. Regularly wipe the detector with a damp cloth to keep appearance clean and fresh. Do not use harsh chemicals to clean products.7. Please do not put the water container next to the charger, so as not to splash out and cause overheating, leakage or failure of the charger.8. Do not charge the instrument in these places: Where the sun shines directly; Where the outside temperature is below 0 degrees or ab
