Wreck-diving is a discipline as different from open-water scuba as
college is from kindergarten. The basic certification course
introduces a non-diver to the subsurface world, and provides him
with the essential knowledge and skills necessary to enable him to
immerse his body in water and discover that, with artificial
devices, he can still breathe. However, a check-out dive and a
C-card do not prepare a person for the rigors of wreck-diving. Most
certifying agencies offer specialty courses designed to present the
entry level diver with new challenges, encouraging him to improve
his proficiency under controlled supervision. This step-by-step
approach is good because it ensures that a diver does not get in
over his head, so to speak, by taking on more than he can handle.
What the beginner sometimes fails to realize is that dives conducted
in different environments and under a variety of conditions require
an intimate understanding of himself and his limitations, and of the
water into which he is about to plunge: the ocean is more than a
pool with a larger circumference. By increasing his skills
incrementally and by gaining a gradual appreciation for the deep, a
diver can achieve his full potential safer and more rapidly.
This book is a primer for one particular and very captivating
activity: diving on shipwrecks. It proposes to offer practical
information, as opposed to theoretical or mathematical; that is, how
to conduct a dive on sunken ships, not what happens to the body
under pressure. Furthermore, it intends to address the grimmer
realities that are often overlooked: entanglement, equipment
flooding, seasickness, and getting lost at sea, to name a few. To a
certain extent, these unfortunate events are overemphasized in order
to make up for the fact that they are seldom addressed in class or
in popular publications: they make uncomfortable enlightenment at
best. My intention is not to scare anyone off, but to acquaint
people with worst case scenarios that may never occur, and to impart
information that is otherwise unobtainable.
The topics covered include equipment modification, thermal
protection, access to sites, current and surge, wreck orientation
and navigation, night diving, photography, pharmacology, and a
riveting rivet by rivet account of how shipwrecks got the way they
are and why they look the way they do. The text is extensively
illustrated with color photographs from the author's collection;
eight illustrations demonstrate the evolution of shipwreck collapse,
from an intact hull to a field of debris.
Primary Wreck-Diving Guide is the first of the three Wreck-Diving
Guides. It is followed by the Advanced Wreck-Diving Guide (deep air
diving, decompression methods, wreck penetration, and more), which
itself is followed by the Ultimate Wreck-Diving Guide (which
introduces nitrox, mixed gas, accelerated decompression using
oxygen, and other high-tech concepts).
The Technical Diving Handbook

The Ultimate Wreck-Diving Guide was the seminal book on technical
diving: the primogenitor of its kind. It was written at a time when
nitrox, accelerated decompression, helium mixes, rebreathers, and
other emerging techniques and technologies were yet in their
infancy. The publication of the original volume propelled deep
diving into far deeper realms of the dark abyss.
The Ultimate, as it came to be called, was considered pure heresy by
those who opposed progress. The purpose of the book was to introduce
to the information-starved masses that a small group of exploratory
divers was stretching the underwater envelope, and how they went
about doing it. Call it an awareness guide.
Ignited by the author's vision, technical diving has taken off like
a launched rocket, accelerating faster with each passing moment and
carrying with it a payload of unknown dividends. What began as new
phase in the slow progress of underwater exploration has grown with
Evolution became revolution. Almost overnight, the concepts of "high
tech" and "extended range" diving entered the forefront of human
The rite of passage is over. Technical diving has come of age.
Underwater explorers can now share the benefits of space-age
spin-off hardware and developing decompression methodologies. The
present volume incorporates recent innovations that were unavailable
until only a few years ago, and in some cases were nonexistent when
its predecessor first saw print.
Acquaint yourself now with such new and exciting devices as the
programmable nitrox wrist decompression computer, the personal
computer interface, the hoseless pressure gauge, a heads-up mask
display, decompression software for laptops, a submersible electric
heating pad, and more.
Also included in this handbook are equations and tips for blending
nitrox, trimix, heliox, and heliair; instructions on how to build an
in-water oxygen decompression station; the procedures and the
chemicals needed to clean tanks, valves, and regulators for oxygen
service; and a complete chapter on how to plan and conduct
expedition style mix-gas diving operations.
The previous book was the ultimate. This one goes beyond.
