Abstract
A portable data sensing and processing device for a SCUBA diver using a tank of compressed air wherein the device provides integrated information to the diver on a liquid crystal display screen to permit the diver to make a longer time variable depth underwater dive than would be permitted by the U.S. Navy dive tables for a no-decompression ascent.
