Abstract
An underwater navigation system for indicating a return direction from an underwater return position to a starting position includes a processor and a power source, a three-dimensional compass, a timer, a water speed sensor and a display interfacing with the processor. The processor is adapted to determine a direction of the starting position relative to the underwater return position based on data received from the three-dimensional compass, the timer and the water speed sensor.
