Spy Spot has just released a new Bug Detector which is very advanced and has multiple detection modes. It can locate hidden cameras while also locating GPS Trackers on vehicles, listening devices, WIFI, and Bluetooth devices. The Bug Detector comes with a magnetic probe attachment that scans for magnets and will vibrate if it detects any. It includes an antenna to expand the signal so the device will buzz or vibrate once it picks up a device ranging on a certain frequency.
