Feature 1Using advanced microcircuit control processors, precise positioning and strong antiinterference. 2Adopts a 360degree tip point probe design, it can detect in the narrow gaps. 3Vibration and blue light LED light alarm can prompt you the location of the metal in time. 4Advanced signal processing technology, when the vibration frequency increases, the closer the detection target is. 5Air compression sealing design is adopted, and the battery can be easily installed without the aid of any tools. 6When the battery voltage is low, the sensor will remind you to replace the battery in time. 7Uses seamless buttconnected full intelligent switch technology, can control startup or shutdown without any adjustment actions.Condition: 100% Brand NewItem Type: Metal FinderMaterial: ABSDetection Technology: Impulse Induction (PI)Detection Mode: All MetalsAlarm Method: VibrationDetection Distance: Underwater 30m / 98.4ftBattery Attributes: 1 x 9V (6F22) Battery (Battery Not Included)Weight: Approx. 408g / 14.4ozProduct Size:Length: Approx. 38cm / 15.0inProbe Diameter: Approx. 5cm / 2.0in .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Metal Detector (Battery Not Included)1 x ManualNote1.Please allow 0-1 inch error due to manual measurement. Thanks for your understanding.2.Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard.3.When detecting metal, the increase of the amount of pulse vibration indicates that the closer the detection target is. Of course, the strength of the pulse vibration depends on the size and distance of the metal shape. This is a high-precision electronic instrument. Please wipe it clean and keep it properly after use. The appearance of this product is sturdy and durable. Please do not use it as a crowbar or digging tool during use to avoid damage to the machine. When the instrument is not used frequently, please remove the battery to prevent possible leakage of the battery.
