OZTRIP CAR COMPUTER - Robert Priestly
Whether on land or sea, the OzTrip Computer can be used to display trip
info on 27 functions of speed, fuel, time, and distance of your
�vehicle.� It also includes a sprint timer which is ideal for timing a
standing quarter mile, plus it can be used as a general-purpose data
logger not even related to vehicles.
