ABSTRACT:
A gauge for warning a scuba diver of an unsafe rate of ascent in the ocean or sea. The gauge is normally attached to the diver's forearm or wrist by means of straps. As the diver ascends, water flows through the gauge. A disk which is pivotally attached within the gauge in the path of the water flow moves in response to the water flow. As the disk moves, an indicator attached to the disk moves along a calibrated scale. As the diver's rate of ascent exceeds a predetermined safe rate, the indicator moves into a marked unsafe zone, thereby warning the diver of an unsafe rate of ascent.
