Features:-There are 4 detection modes, magnetic field detection mode, which can find widely used magnetized GPS trackers; camera lens finder mode, which can find hidden pinhole cameras with a simple visual inspection through infrared laser scanning; RF signal detection mode, which can detect active RF bug transmitters such as transmitting cameras, GPS trackers, wireless audio bugs; anti-theft alarm vibration sensing mode.-With 2 alarm modes, beep and vibration, and 5 levels of adjustable sensitivity, it can be applied to various situations.-With the help of the third-generation smart chip, this detector not only helps to expand the detection range to 1MHz-6.5GHz, but also enhances the anti-interference ability, which can quickly detect 2G/3G/4G/GSM signals.-.
