Detailed Description

RU2Fast Radar Speed Dolly

The ORIGINAL Speed Radar Dolly - Fast-500 radar dolly has kept school children and other pedestrians safe for more than eight years. RU2Fast speed display dollies are built in the USA using the finest materials. The Fast-500 radar dolly is built to provide you with many years of reliable service. For industrial applications like PIT traffic, the Fast-500 can reliably read down to 1 MPH. The radar signs feature a full matrix high intensity LED display with 12" characters to make it readable up to 750 feet and is appropriate for lower speeds (sub 35 MPH). In cases where that's "too much information" the Fast-500's radar sensitivity is adjustable to 5 increments. In addition to the standard flashing digit alert, several additional violator alerts are available including a "SLOW" message and our flashing Red/Blue bars which are particularly effective at night.
