V.L.F. probe tests your AC outlets, phone lines, or suspicious wires for very low frequency "carrier current" signals.

The audio feedback test utilizes the CSR-1 speaker to cause sound regeneration with the microphone of the hidden transmitter. This is positive proof of the presence of a listening device.

The CSR-1 is very "user friendly", unlike many units costing hundreds of dollars more.

Headphones are included to allow you to listen to transmitters without alerting the eavesdropper.
