Understanding and Applying Decompression Dive Tables is an online tutorial that explains basic dive physiology, gas physics, and the use of recreational dive tables to plan no-decompression dives.


Gary's software utility page contains several SCUBA-related dive calculators (e.g., PADI and NAUI dive tables, and Nitrox maximum operating depth calculators), an EAN Gas Mix Calculator, and Latitude/Longitude coordinator converters.


Gary's SCUBA and mariner Web bookmarks has pointers to many Web sites, including dive shop links, educational resources, marine documentation sources, and more.
