Highly Sensitive Metal Detectors: Metal detectors allow you to quickly scan large areas and then use a precise locating tip to narrow and pinpoint targets before digging. The strip probe design allows you to hold the metal detector in your hand. Simple operation: When a metal object is detected with a single button, an LED lights up. At the same time, a Bi-Bi alarm sounds. The intensity of the alarm increases as the detector approaches the metal target. This unique feature helps the user determine the exact location of the target. Lightweight and portable: 1/3 the weight of a traditional metal detector. Comes with a plastic elasticated webbing, belt sheath and carrying case to make it easy to carry or hang, preventing it from being dropped or lost. PARTIAL WATERPROOF: The pointer of the dust metal detector is partially waterproof. You can sink this part into water to check whether there is metal in the water. However, it cannot be used under water, and the switch and horn are not waterproof. WIDELY USED: This metal detector pin can do all types of work such as searching for coins, gold, silver, artifacts, jewellery, helping you to easily locate treasures or lost metal objects, whether indoors, outdoors, on walls, in sand, grass or soil, and even in extreme temperatures ranging from -35F (-37C) to 158F Package: one metal detector (batteries not included)
