Composite, fiber-wound cylinders are making their way back into diving in rebreathers and other advanced scuba gear. The weight and lifespan benefits of these cylinders are attempting to challenge their previous cost barrier.
The 11-liter aluminum 80, aptly named for its 11-liter internal volume and 80-cubic-foot capacity when filled to its 200 bar/3,000 PSI rated pressure, is by far the most common cylinder. Just because it is the most common, however, may not mean it is the right one for you. Cylinders come in a wide variety of […]
As the field of recreational diving continues to evolve, DAN remains committed to being at the forefront of safety and scientific advancement. The purpose of this article is to educate […]
GETTING COLD ON A DIVE IS UNPLEASANT, but if it progresses to hypothermia, it becomes potentially fatal. Even more than discomfort, considering the physiological and psychological stress it can cause, being cold is potentially risky.
SURFACE MARKER BUOYS (SMBS) AND DELAYED SURFACE MARKER BUOYS (DSMBS) are common and essential safety devices. These brightly colored, inflatable tubes, sometimes called safety sausages, are critical pieces of equipment that divers should take on most dives. Divers most often use them as signaling devices to mark their locations below the surface and alert boat […]
DES TERMES DIFFÉRENTS PEUVENT PARFOIS DESCRIRE le même équipement dans l'industrie de la plongée. Ce que certains plongeurs appellent une lampe de plongée, par exemple, d'autres l'appellent une torche de plongée. Les deux étant physiquement identiques, les noms sont interchangeables et ne causent au pire qu'une confusion mineure.
L'éclairage de plongée est un équipement essentiel qui peut être utile à tous les plongeurs lors de la plupart des plongées. Il existe plusieurs types d'éclairages avec des utilisations différentes et quelques considérations clés à prendre en compte avant l'achat. Il n'existe pas d'approche unique en matière d'éclairage de plongée. Chaque plongeur doit donc examiner attentivement ses propres objectifs et besoins avant de choisir le modèle le plus utile.
Chaque année, de nouvelles technologies améliorées font leur apparition dans l'industrie de la plongée. Ces progrès peuvent rendre la plongée plus sûre, plus agréable, ou parfois les deux à la fois.
THE DIVE KNIFE IS AN ICONIC PART OF A SCUBA DIVER’S GEAR. Since the inception of diving as a recreational activity, the dive knife’s presence in a diver’s equipment has influenced the public image of scuba diving as a dangerous sport and placed its participants in a league of their own.
IN THE 1900s UMBERTO PELIZZARI was a young diver from Busto Arsizio, Italy, who was making headlines by breaking world records in constant weight and variable weight freediving. Needing an edge against his archrival, Francisco “Pipin” Ferreras, he sought advice on fins from a friend who was knowledgeable about innovative freediving equipment: Valerio Grassi, founder of Omersub.
