Feature: 1. HIGH ACCURACY: Specific types of metal can be identified by frequency regulator. The metal finder kit features a remote search system and a accurate location detection system. Moreover, the detection range can up to 1000meter, and the underground detection depth can up to 30meter 2. KEY DESCRIPTION: Digital display meter knob can adjust the frequency and percentage, press the knob to adjust the frequency size, press on/off to switch to adjust the percentage, the left knob to adjust the depth, the left knob to adjust the range, the front knob is the position key, there is a sensitivity lever behind, can improve the detection sensitivity, there is a power switch, can open or close the metal detector 3. DETECTION PROMPTION: When the metal position is detected, the metal detector will sound and prompt, the better the sound continuity, the more accurate the position 4. WIDE APPLICATION: Whether you are a beginner or an advanced metal detector expert, metal detectors are always right for you. Handheld metal finder is suitable for treasure finding, looking for gold, silver, copper and precious stones 5. FUNCTIONS AND USES: The underground metal scanner can accurately determine where objects are buried, and the search system is controlled by a microcomputer processor and is reflective conductive Specification: Item Type: Metal Detector Depth of Detection: Maximum Detection Depth: About 30meter For a 5cm x 5cm object, you can detect at least 8meter For an object of 30cm x 30 cm, it can detect 5-8 meters, and if an object of that size is buried long enough, it can detect up to 30 meters The larger the area of the object, the deeper the detection will be Specific Functions: Accurately determine the buried location of the object Search System: Microcomputer processor control and reflection conductivity Search Area: Approx. 1000meter / 3280.8ft Detection Depth: Approx. 30m / 98.4ft Battery: 1 x 12V 1000mAh rechargeable li ion battery Transmission Frequency: 5.6-6KHz Sign Frequency: 990Hz Detection Types: Gold, silver, copper, jewelry, etc. .
