Delta V
                             

In areas of high RF activity, such as big cities, interference can make it difficult to pinpoint local active
RF transmitters. When time is short nd high-level emergency or external meetings are required it is
essential to be able to quickly and easily locate active radio eavesdropping devices.

Delta V is a handheld differential RF field-strength wide band detector. Rather than measuring the
absolute field strength, Delta V measures the rate of change in field strength. Ideal for use in areas
with high RF activity, this technique provides a high degree of rejection of strong distant signal sources,
providing greater discrimination against outside signals. The result is accurate location of active radio
listening devices, wherever the meeting.

A Push Button is provided to reduce the sensitivity of Delta V whilst working close to a local transmitter.
This prevents a maximum response occurring too far from a transmitter to locate the source accurately.

Portable, quick and simple to use, Delta V is the ideal tool for quick location of active listening devices.
