The DSP-20 is a dual channel vehicle detector with built-in directional logic controls. Front panel switches allows the user to select between two independent channels or directional logic mode.
The DSP-20 is a dual channel detector that uses advanced channel scanning technology to provide superior noise tolerance. The scanning technology allows for placement of loops closer together (even overlapping) than ever possible with single channel detectors.
