Vibration-type hand-held needle detector
Description: aka: hand-held needle detectors, hand-held needle detectors, this type of hand-held portable needle device system device. Using magnetic field principle, can accurately detect the needle and other iron items specific location. The thin pieces and small items for testing very. And for large needle detected after the hand-held needle detector can help you find exactly small needle or ferromagnetic metal really is here to avoid metallic contamination or mechanical harm to consumers, and improving product quality.

Main features:
Switch with vibration and sound alarm function;
Easy to operate and light to carry, Detecting high sensitivity;
Imported high-end digital chip, performance is more stable and durable;
Can accurately identify needle (metal) location;
Continuous long-term work, not heat, does not produce overload;
Voltage is lower than 6V will produce less than a row of their calls, said power shortages should replace the battery.
