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.

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).

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.

The Ames Pro GPS-DMI 250 is an all-in-one version of our Pro GPS-DMI for users wanting the most straightforward distance measurement system possible. It uses DGPS signals to measure linear distance, with data from the OBD-II port on your vehicle for …

The NiteStar is a Distance Measuring Instrument (DMI) designed to accurately record distances and survey coordinates as you drive. The device records distances for logging points along a given route and gives you linear distances with a high degree of accuracy.

The Ames Pro GPS-DMI is a Distance Measurement Instrument that uses a GPS receiver to measure pavement distances, replacing traditional encoder-based DMI systems. Nothing else on the market today works more efficiently to guarantee accurate distance measurement.

The GPS-DMI Pro Distance Measuring Instrument (DMI) from MH Corbin is designed to complete a typical distance measurement survey using just four keys. The device records distances via GPS for logging points along a given route and offers linear distances with …
