Add GPS data to Nitestar® DMI Systems.

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 a superior degree of accuracy. 

The GPS-DMI Pro connects into a vehicle’s OBDII port and uses both vehicle distance data and GPS data to provide distance information to the Nitestar NS50 or NS60 DMI display unit. 

Moving the GPS-DMI Pro from one vehicle to another can be done in just minutes. The GPS-DMI Pro receiver is sold as a stand-alone device to be used with the Nitestar NS50 or NS60 DMI.
