On-board GPS distance measuring, coordinates and data memory. No Calibration. No Installation. No External Sensor required. Accurate, reliable and easy to operate, our RAC GEO II units are the industry standard Distance Measuring Instrument (DMI).

Measures precise speed in mph, fps, and kph. User selectable signalling source, Vehicle Speed Sensor or GPS. Event/Data logging to log multiple fields just as a user-defined event numbers, speed, aerial and traversed distances, and GPS coordinates.

The RAC-GEO-II is the most accurate and powerful GPS DMI on the market. The RAC-GEO-II is built to last, with high grade components and a proven industry track record. Skip the process of trying those cheaply made, short lived units made by other brands. Let our decades of DMI development experience work for you.

The CS1100 can be used to measure distances with an accuracy error less than 0.05% and a measurement repeatability over 95%. Just connect power and the GPS antenna will acquire multiple satellite constellations. The large touchscreen gives the user the ability to add a start station, station direction, pause the count, or reset the stationing.
