A head up display system includes first and second optical waveguides. A bracket holds the optical waveguides in a spaced-apart fixed relationship to one another such that their optical axes are separated by a distance of 63.5-65 millimeters. The optical waveguides are angularly disposed with respect to one another to produce a binocular image whose focal plane is located out at a distance of 2-4 meters. The bracket also specifically positions the optical waveguides adjacent to a transparent face plate of a dive helmet or dive mask.

A breathing-air tank pressure tracking system includes a housing having lights mounted therein. The lights are spaced-apart from one another and disposed along a line. A pressure sensor is coupled to a tank containing pressurized breathing air. The pressure sensor detects a pressure of the pressurized breathing air and produces a signal indicative thereof. The housing is configured to be coupled to an exterior portion of a dive helmet wherein the lights are positioned in a field-of-view of a user wearing the dive helmet. A controller, mounted in the housing, is coupled to the pressure sensor and the lights. The controller activates selected ones of the lights based on the signal received from the pressure sensor.
