The Certified Diver’s Handbook

This book has excellent diving information for everyone from beginners to Undercurrent subscribers. Long-time diver and writer Clay Coleman covers everything from diver lingo to wave action, and The Certified Diver’s Handbook comes closer to putting it all between the covers of a single volume than any other effort we have seen. Humberto Fontova, author of The Helldiver’s Rodeo, puts it this way: “From masks to valve regulators, from rip tides to thermoclines, from fireworms to sharks—Clay overlooks nothing! You’ve never been through such a comprehensive course.” 384 pages; list price $22.95; order now and pay only $15.71. Log on to Undercurrent.
