Unique For those interested, there is no need to buy a metal detector. In addition, this metal detector has a greater detection distance than other metal detectors of this type [sensitivity: 50 cents for 8 cm]. [Sensitivity: 50 cents for 8 cm]. Widely misused due to its high price. It can be used as a multi-hundred-dollar device. The extended probe section brings the probe length of the detector to 12.5cm for the first time, while the detectors available on the market only have a probe length of 7-10cm. A longer probe means a wider detection area. 3 levels of sensitivity for a 360 detection area There are three levels of sensitivity with different torches (3 LEDs), audio reports and differential vibrations between the sensor and the object. The closer the object, the louder the sound and the green LEDs flash one after another. Unnecessary searches are avoided. Save time on the hunt The detector operates with one button and is easy to use. When the detector is close to a metal object, it will automatically flash, give an alarm and vibrate. This detector is ideal for adults. Thanks to its adult size, the detection distance has been improved. It can be used as an auxiliary instrument for large metals or as an everyday instrument. Compact, lightweight and portable design The professional metal detector is 28 cm long and weighs 0.2 kg. The rotating part of the detector needle is waterproof according to IP66 standard.
