ABSTRACT:
A portable device to determine highway marker locations including an enlarged disc dial having graduated scale markings on each side thereof and therearound representing increasing and decreasing highway mileage markers, respectively, and smaller disc dials superposed on either side of and centrally rotatably and lockably mounted thereon. The latter are provided with scale markings therearound representing vehicle odometer readings. To keep track of a vehicle's highway location, the user visually notes the last highway marker passed and rotates the small dial until the last two digits of the vehicle odometer reading indicated on the dial scale are aligned with the scale marking on the appropriate large intermediate dial (either increasing or decreasing, depending on direction of travel) corresponding with that mile marker, and the three discs are locked thereat. Thereafter, and for the remainder of that trip, the present nearest mile marker location of the vehicle may be determined by viewing the odometer reading and then looking at the device and reading directly from the scale on the appropriate large dial, the mile marker that aligns with the last two digits of the odometer reading.
