Abstract
Device for and method of dive monitoring, wherein the pressure in a diving flask of a breathing equipment and the ambient pressure which the diver is exposed to at the respective water depth are detected. A decompression computing means is used to determine the respective decompression stops which the diver has to observe in surfacing, and how much time surfacing will require altogether. A performance index is derived from the variation of the pressure versus time in the diving flask, which index is a measure of the physical work performed by the diver. This performance index is supplied to the decompression computing means and is considered in the calculation of the total surfacing period.
