Deep Diving Overview

Deep diving is sort of a relative term, as a deep dive for one person may not be a deep dive for another. Books have been written about deep diving and there has been much controversy over the years with respect to how to deep dive, what gasses to use, decompression techniques, etc. If you’ve browsed around on some of the training websites, you probably noticed a specialty certification called Deep Diver. What does that mean exactly? For training agencies like NAUI and PADI, this certification teaches you to dive from 60 to 130 feet (18 to 40 m) following no decompression requirements. You also probably noticed that if you were to take an Advanced level certification, you would also be exposed to at least one deep dive.

Technical Training

Technical wreck diving training is designed towards highly motivated individuals who desire to explore wrecks beyond the limits of standard recreational diving limitations. Technical wreck diving is making penetrations inside a wreck beyond the natural light zones, deeper than 130 fsw, and requiring stage decompression. Because of the lack of direct access to the surface and the potential for disorientation or silt-out, special procedures are utilized when exploring the interior portions of wrecks.

Technical wreck diving training involves taking a course or series of courses from a training agency such as TDI, NAUI, PADI, IANTD, or GUE. Technical wreck diving training is designed to provide you the skills and knowledge needed to gain the experience and minimize the risks in penetrating wrecks, decompressing, and diving to depths greater than 130 fsw. Throughout the training, you learn the skills needed to plan and execute dives that take you deep inside a wreck.

Recreational deep diving training teaches you to safely dive to a maximum of 130 feet (40 m). Training agencies such as NAUI, PADI, and IANTD offer this type of training. There are two ways to receive deep diving training. Most training organizations teach and require at least one deep dive when taking their advanced level certifications. Most of them also offer a specialty certification called Deep Diver, which also teaches you do dive between 60 and 130 feet (18 to 40 m). For details about each of the courses, contact your instructor or training agency. Each training agency may require different prerequisites and have a different approach to the training. Make sure you understand and are comfortable with the type of training offered. Learning, understanding, and practicing are why you are there, not just to quickly get another certification card.
