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., by way of specifically operating the multiple keys or buttons on the keyboard in various specific steps in order to achieve, for display or the like, the desired navigational information. A protractor/graduated scale and a pop-up lens extend from the navigational instrument for use in orienteering, mapping or course plotting. An infrared sensor is provided for use at dark environments for detecting the presence of “hot”bodies. An optical input/output port for serially interfacing between the internal CPU of the instrument and another electronic device, computer or the like, is also provided. The internal components are effectively arranged between upper and lower casings to provide a very compact and portable navigational instrument which can withstand the worst or weather conditions.
