The Series 9000 GPS Interface System provides the same functions as Series 7000 instruments PLUS the important addition of nautical Miles Per Gallon over the ground. The speed signal required to calculate the nMPG reading is obtained from GPS and Loran systems having a NMEA 0183 serial port output.

The direct display of nautical Miles Per Gallon over the ground gives the skipper a powerful new tool to set optimum fuel efficiency under all conditions and to determine precisely how far he can go with his remaining fuel.
