Les utilisateurs doivent utiliser les bouteilles en respectant les paramètres de conception, notamment en ne les remplissant qu'à la pression de service nominale et en les faisant inspecter par des techniciens formés et qualifiés et en les faisant requalifier par une installation d'essai réputée et reconnue. Plus de 90 % des ruptures se produisent pendant le remplissage, c'est pourquoi il est essentiel de procéder à une inspection diligente au cours de ce processus. Les bouteilles devraient fonctionner en toute sécurité pendant toute leur durée de vie si les utilisateurs respectent les conditions de conception et d'utilisation.
The U.S. currently has 14 national marine sanctuaries and two marine national monuments, and each has its own unique story. In preserving these irreplaceable resources, the sanctuaries protect who we are at our base — our soul as a nation. They reaffirm us and connect us to our incredible heritage.
Crocodiles are apex predators, and in the wrong place and time, humans are potential prey. There are exceptions, but most of these wonderful and primitive reptiles won’t squander encountering a potential meal. When swimming in any reptile habitat, know who and what you may encounter, or don’t swim at all. The resident American crocodiles at Jardines de la Reina routinely share their waters with snorkelers and divers, but Jen Hayes didn’t feel the same comfort working in Nile crocodile waters in Botswana.
Underwater photographers usually evolve a specialty, but the first fork in their road typically involves defining an interest in either photographing natural history — marine life in particular — or concentrating on editorial and commercial work that inevitably involves photographing people underwater. Photos of charismatic marine life help tell the story of a dive destination or might be used for photo décor or stock photography. Compositions that illustrate people interacting with marine life bridge both disciplines and combine each approach’s rewards and challenges.
With nearly 16,000 miles of rugged coastline and more than 40,000 islands and islets, British Columbia’s Howe Sound features fantastic marine life and spectacular coldwater scuba adventures. Stretching 27 miles from its narrow head under lofty mountain peaks at Squamish to its wide-mouth opening into the Strait of Georgia just northwest of Vancouver, Howe Sound is North America’s southernmost fjord. This sea-to-sky corridor crafted by glaciers and perfected by time seems tailor-made for subsea exploration — reef and wreck, rec and tech.

Divers can’t save themselves unless they understand what’s happening and how to evaluate the problem, keep breathing and act. It sounds simple, but the rescue diver course helped me solidify my safety and survival skills. I may not remember every detail, but one item still stands out for me as invaluable for a new diver: Any dive can be stopped at any time, for any reason, without question. To that I would add “and without embarrassment.” That advice would eventually save me.
