A Word of Caution - Please Read!

The material presented in these pages is provided for educational and informational purposes only. Reading any of this does not qualify divers to dive some of the sites described. Many deep wrecks and caves have low visibility, restrictions, and silt that will challenge the most advanced divers. Please obtain the proper training from an organization specializing in technical and cave diving like GUE, NACD, NSS-CDS, or IANTD before attempting this kind of diving.

No amount of previous open water diving experience or training can adequately prepare you for technical diving. According to the National Speleological Society, Cave Diving Section (NSS-CDS), more than 431 untrained, inexperienced, and improperly equipped divers have died since 1960 while cave diving in Florida, Mexico and the Caribbean. No less than 19 were fully certified open water Scuba Instructors. However, they lacked any training in the specialized area of cave diving.
