What is deep diving?
Deep diving can be broken down into two levels: recreational deep diving and technical deep diving. Recreational deep diving is diving to depths between 60 and 130 feet (18 to 40 m) following no decompression requirements. Technical deep diving is diving to depths beyond 130 feet (40 m) using staged decompression methods and the proper gasses, like trimix as the bottom gas and nitrox and oxygen for decompression.
Do you need a special certification to deep dive?
You need special training and certification. There are recreational (advanced level and deep diver) certifications to properly train you in diving to a maximum depth of 130 feet (40 m). Most dive charters require an advanced level certification to dive deeper than 60 feet (18 m). On the technical side of deep diving, you need to go through trimix certification training, staged decompression training, and understand all of the parameters required to safely dive deeper than 130 feet (40 m).
Do you need special equipment to deep dive?
At the recreational level, standard open water gear is generally all you need. At the technical level, there is much more gear that you’ll need, from double tanks with manifolds to stage tanks and the proper exposure suit. The gear requirements are much greater when technical deep diving.
Why would you want to dive deeper than the recreational limits?
Diving to depths greater than 130 feet (40 m) and entering decompression requirements is a much more advanced level of diving. However, the rewards of being able to explore to greater depths to see a wreck, cave, wall, or blue hole can be exhilarating. Deep diving in the technical community is not about going deep, it’s about having to go deep to explore the wreck, cave, blue hole, or wall that you want to see. Many dive explorers and adventurers strive to see and learn about what lies deep in our oceans, lakes, and springs. This desire pushes them to be able to dive deeper.
Is deep diving safe?
Deep diving is safe as long as you receive the proper training and properly use what learn in your training courses. By following the techniques, procedures, and philosophies you learn in training, deep diving can be very safe. However, if you have a maverick or reckless attitude, deep diving may not be for you.
