Abstract: A personal multi-purpose navigational instrument which can be hand held and portable for transporting at long distances is disclosed. The navigational instrument can receive, process, display, store and interface data for navigational use, such as, bearing information, inclination and declination,temperature, barometric pressure, current and elapse times, or the like. The navigational instrument has an internal flux gate magnetometer, solid state temperature sensor, solid state barometric pressure sensor, infrared sensor, and real time clock. The navigational instrument has a foldable LCD display for outputting the desired navigational information and a keyboard for instructing or inputting information through an internal microprocessor. Numerous functions can be performed as desired by way of the operations performed by the user on the keyboard; i.e.
