Advanced Nitrox
Student practices her valve drills above USS Spiegel Grove, Key Largo, Florida
Often the first course as you "go tech" the Advanced Nitrox Course introduces the fundamental academic and in-water skills required to safety and effectively plan decompression dives to the training depth of 140 fsw with a maximum of 15 minutes decompression.
A classic benefit for this course is the ability to do one long dive at the same (deeper) site while other divers do a short dive then sit out for an hour surface interval before another short dive.
The ability to spend more bottom time exploring the wreck or site with minimal decompression and not having to spend what can frequently be an uncomfortable hour surface interval is what frequently guides people to this course.
Depending on the individual divers prior experience, air consumption and physical needs this course can be taught using a larger single scuba tank or the more traditional twin tank configuration, a.k.a "doubles".
