Delta V Advanced – Detecting real time RF listening devices

The Delta V Advanced is a compact handheld differential RF wide band detector. Measuring the rate of change in field strength enables accurate pinpointing of local RF sources, quickly and efficiently.

Designed to protect against real time streaming from surveillance bugs, by detecting and locating their signal, then using audio and visual alerts to guide you to the target. Highly effective when searching rooms, venues, people and objects, Delta V is an essential part of any TSCM tool box.
