Stronger Magnetic Field DetectionBug detector is an effective rf signal & magnetic field detector that helps you detect hidden cameras, GPS trackers. The bug detector uses a new digital linear detection chip, which is more sensitive to magnetic field detection. The detection range is increased, the working time is longer, more stable and accurate, and professionally protects your privacy. Dual Function CompatibleThe electromagnetic wave and magnetic field detection functions can be used at the same time, and there is no need to switch modes frequently, which increases the workload exponentially. The two functions can also be used at the same time to verify each other, and accurately find out the possible hidden devices. MultipurposeThe anti spy detector can accurately detect 1.2G~5.8G wireless cameras, hidden miniature cameras, wireless audio bugs,2G/3G/4G/WIFI signal bugs, wiretaps, mobile phone tapping, GPS trackers, magnetic GPS tracking devices, and other bug
