S-80 and S-80 MC

M.P.H. Industries

CPL Approved -- single antenna and no auto-lock

Some units use automobile speedometer cable to measure patrol car speed instead of the radar (moving mode only). This feature is intended to eliminate batching errors, and allows officers to operate radar in stop and go traffic without switching radar between stationary and moving mode. OPERATION
