This handheld needle detector operates using magnetic field sensing technology and features a one-button adjustment for high and low sensitivity settings, enabling accurate detection of broken needles and other ferromagnetic metals. Its lightweight design makes it particularly suitable for detecting thin and small items. It can be used as a follow-up tool after larger needle detectors to provide precise localization within a small range. Widely applicable in industries such as apparel, food, and pharmaceuticals, the device is equipped with a triple alarm system (light, sound, and vibration), allowing users to choose their preferred alert mode. Powered by easily replaceable AA batteries, it offers simple operation and exceptional practicality.
