The PSAI Cavern Manual Updated and Revised

Everyone is now very aware that PSAI holds the highest standards in keeping our manuals at the leading edge, providing our divers and instructors with the very best. The PSAI Cavern Manual has been updated and revised. The PSAI Executive Board would like to thank PSAI Instructor Trainer German Yanez for his contributions. German is responsible for the new cover photos as well as some new photos that are distributed throughout the chapters of this manual. He also provided some very nice cavern/cave maps that have been added to the PSAI Cavern Manual.
