The world's first power heated wetsuit

2010-02-09T09:13:00.000-08:00

The idea was straightforward. Design and build the world's first power-heated wetsuit. The concept was unique. Rip Curl has made the best surfing wetsuits since 1969, but never before have innovation, technology and science so meticulouslly challenged.

The plan was precise. Research, development, testing and production unrivalled. Succes would open up a new frontier for surfing exploration. Failure was not an option.

The Rip Curl H-Bomb is now a reality. It has conquered the extremes of the Artic Circle. It is backed by oru elite surf team and performance tested by World Champion Mick Fanning.

The H-Bomb use 2 lithium-ion 7,4 volt batteries. Each battery weighs 120g. Batteries are rechargeable. Recharge time is aprox 3 hours to restore full power. The batteries power up heating elements on your back.

The batteries are carried in internal pockets on the lower back, positioned so there's minimal impact on your flexibility.

The temperature of the elements is controlled using 3 settings on the switch.

How to properly clean and your regulator after diving

2009-03-27T11:16:00.000-07:00

This instructional video by Scuba.com will show you how to properly clean your regulator after a day of diving. You can keep it clean and in good condition if you rinse it with fresh warm water to remove all the salt. It will also help if you have the ability to attach it back to a tank and blow all the remaining water out. As always, a yearly inspection at your dive shop is needed.

Pee-valve for women

2008-11-24T10:36:00.000-08:00

Thanks to better drysuits and cylinder configurations, people are spending more time underwater, and if you keep drinking plenty of liquids, there will come a time when nature calls.

The She-P makes it possible for female (technical) divers to comfortably use a P-valve while diving in a drysuit instead of using diapers.

The She-P is a soft silicone device featuring a reservoir with ‘output’ tube, that has flexible ‘wings’ that are designed to be adhered to the skin with a medical adhesive intended for use with prosthetic devices. This results in a proper seal and comfortable urinating.

The price is 84 € for a She-P and 278 € for the complet kit.

In the following video shows the process of manufacturing a jacket, jackets seem manufacturer's Aqualung, according to the anagram is seen in the video.

As you will see this is a rather long and laborious process. Having seen the video you may no longer seem so expensive the price of the jacket.

Making a scuba tank

2008-09-03T05:31:00.000-07:00

In this video is all the process of manufacture of the scuba diving tanks that so many times we have loaded to our back. It is a somewhat peculiar process of manufacture and it never is of more knowledge since our diving gear is done, since it allows us to know it more and to understand better his operation.

The video is somewhat long but I personally have found it very interesting.

WASP Injector Knife

2008-07-25T05:17:00.000-07:00

Nobody wants to engage in hand-to-hand combat with a dangerous marine predator. These situations, as uncommon as they may be, can occur. Until now, the diver has been extremely vulnerable and defenseless.

The WASP Injection Knife gives you the ability to defend yourself with deadly force and, if nothing else, it gives you peace of mind and increased comfort while reducing diver stress levels.

When you are crawling around inside a shipwreck with your whole world illuminated only as far as your dive light will allow it is nice to know that you are carrying a weapon that can truly protect you.

As divers, we all know what the effects of compressed gas are underwater. Our training teaches us that our lungs would burst from over-inflation if we held our breath and rose to the surface. This principle is key to the effectiveness of the WASP Injection System.

This weapon injects a freezing cold ball of compressed gas, approximately the size of a basketball, at 800psi nearly instantly. The effects of this injection will drop many of the world's largest land predators. The effects of the compressed gas not only cause over-inflation during ascent when used underwater, but also freezes all tissues and organs surrounding the point of injection on land or at sea. When used underwater, the injected gas carries the predator to the surface BEFORE blood is released into the water. Thus giving the diver added protection by diverting other potential predators to the surface.

Price: $379.95

Private Luxury Submarine

2007-12-07T09:12:00.000-08:00

SEAmagine Hydrospace Corporation announces that it has just delivered its latest luxury submarine, the Ocean Pearl submersible, which will be installed on a luxury mega yacht in Europe, named the Amevi Surprise, during the fall this year.

The Ocean Pearl submersible represents the latest state of the art technology for underwater exploration specifically designed for the luxury yacht market. This SEAmagine luxury 2-person transparent submersible has a depth rating of 500 feet (153 m) and its transparent spherical cabin offers an unprecedented panoramic view to its occupants. Contacted in 2006 by the luxury yacht Amevi for a small submarine, SEAmagine responded with an enhanced version of its scientific and commercial submersible design with a focus on comfort, safety, and simplicity of operation to ensure a realistic product for the luxury yacht market.

In response to the growing demand from the luxury yacht market for luxury submarines, SEAmagine has designed and produced a version of its manned submersibles specifically to complement luxury yachts. This 1-atmosphere submersible offers comfort, safety, and an exceptional field of view to its occupants in a dry environment not affected by water depth pressure or temperature. With over 72 hours of life support, this environmentally friendly electric underwater vehicle meets all the standards of the latest scientific submersibles but with the comfort and luxury of first class seats underwater. All of SEAmagine’s submersible are classed by the American Bureau of Shipping (ABS), meet the regulations of the Cayman Island Shipping Registry. and have a long-standing record of excellence for over 10 years.

SEAmagine’s submersibles feature a special design from the more traditional concepts, which make them ideally suited for operation from a yacht.

Submersibles tend to be neutrally buoyant vessels and need to be boarded by the occupants while on deck before being hoisted into the water to go diving. Similarly, the submersibles need to be hoisted back on deck for the occupants to disembark. This inherent need of traditional submersible design makes their operation logistically complex, difficult and time consuming. To greatly simplify the operation of a submersible from a yacht, SEAmagine’s design offers a unique patented buoyancy system that permits the small craft not only to submerge but also to float high above the water line. This allows the submersible to be operated as surface vessel and be handled or docked as a regular tender once launched.

The advantages of this feature are wide-ranging and immediate: 1) the submersibles are hoisted without occupants on board. Not only is this simpler and safer, it also allows the use of simpler cranes, eliminating the burden of having the cranes “man-rated.” 2) The launching operation can be performed by crewmembers only without the guests being present. Similarly, recovery of the submersible at the end of the day involves the crewmembers only, leaving the guests to revel in the day’s discoveries liberated from such technical operations. 3) Once launched, the submersible remains in the water as a surface vessel and is docked at the dive platform. Passengers simply step into the vessel when the pilot has it ready and step out when the submersible returns to the docking position. This allows multiple dives to be performed without having to struggle with crane launch and recovery operations for each dive. This greatly simplifies the logistics of operation, safety, enjoyment, and provides more dive time in a day.

Finally, a crucial aspect of manned submersible use is operator/owner support through the life-cycle management of the assets. Manned submersibles are complex machines and their safe and efficient operation for research, work or pleasure is not a one-man show. It is a team effort that involves the manufacturer, owner, operator, regulatory agency and the piloting crew. Technical support for the submersible, spare parts, equipment addition and general maintenance are essential services to an owner for maintaining the value of each vehicle and above all keeping them in use. This can very often be a problem with older or second-hand submersibles.

An important part of the product support and customer service includes the crew and submersible pilot training. Any operation requires that there be a trained pilot in the submersible and a trained surface controller at all times, that maintains communication with the underwater vessel and tracks its position. The yacht captain must be familiar with the launch and recovery process and is part of the safety protocol established during training. Companies such as SEAmagine have developed well-structured pilot training program for its submersibles, which the company initially developed in conjunction with the US Coast Guard for a tourism operation and has kept improving on the process over the years.

SEAmagine’s business is an international endeavor. Operating manned submersibles around the world requires solid technical foundations, a full understanding of certification rules and expertise with national regulatory agencies. “We have led six manned submersible deployments in five different countries,” says William Kohnen, president of SEAmagine Hydrospace Corp., in California. “Expertise counts. Ten years of experience gives us the perspective required to understand life cycle management issues thoroughly that leverages our state-of-the-art technology, our products, training program and skills to provide practical service-oriented solutions.”

Manned submersibles always have and continue to fulfill a dream for many to explore the open oceans, for work or leisure. Today’s state of technology can bring this to reality. “Our approach focuses on people, processes, and technology. We understand people’s dreams of exploring the oceans and we share the passion,” concludes Charles Kohnen, vice-president of SEAmagine. “We utilize a variety of enabling technologies and best practices to help our clients become operational, maintain high levels of safety, and strengthen our relationships to deliver more innovative products and services.”

SEAmagine is a world-leading manufacturer of small 2 person and 3 person acrylic submersibles for the scientific, commercial and luxury yacht markets with depth ratings ranging from 500 feet (153m) to 3000 feet (914m) deep. With 7 submersibles delivered in 6 countries to date, SEAmagine submarines have accumulated over 7000 dives with excellent track record in safety and reliability.

The history behind Scuba Diving

2007-11-29T12:48:00.000-08:00

Scuba is the acronym for Self Contained Underwater Breathing Apparatus. Jacques-Yves Cousteau and Emile Gagnan are considered to be the inventors of the scuba diving kit we have today.

The key terms in SCUBA are ‘Self Contained’, since the alternative forms of diving gear depend on a hose, which leads to the surface of the water. The hose is attached to a pump which forces down air through the hose at such a pressure, which will cancel out the pressure, exerted by the water on the diver’s chest. One such equipment is the diving bell. The earliest versions of diving bells could be called self-contained in one sense of the term because it lacked a hose, and the total air supply available was whatever was already inside the bell. However, the limited air supply constrained the movement and length of time, which the diver could spend under water.

Before Jacques-Yves Cousteau and Emile Gagnan designed the prototype for the modern scuba diving gear, there were some important inventions, which led up to it. Several people tried to develop a self-contained apparatus for divers, such as:

Aristotle is said to have described a diving bell in 360 BCE, and Alexander the Great apparently made several dives using a crude bell in 332BCE.

Sieur Freminet developed the very first self-contained air equipment in 1772 - a ‘rebreathing’ apparatus which would recycle the air inside the diving bell which had been exhaled. However, Freminet died after being in his invention for twenty minutes due to sever lack of oxygen.

William James invented a self-contained air device in 1825. It consisted of a cylindrical iron belt, holding sufficient air for a seven- minute long dive, attached to a copper helmet.

Benoit Rouquayrol and Auguste Denayrouse designed a device in 1865 which consisted of a horizontal steel tank of air attached to the diver’s back and connected to a mouth-piece.

Henry Fleuss built a pure oxygen ‘rebreather’ and it was a closed-circuit device.

Dr. Christian Lambertsen developed a ‘Self-Contained Underwater Oxygen Breathing Apparatus’ for the U.S. military war effort, code-named ‘SCUBA’ in 1939. Even though this apparatus worked well for shallow water diving, the oxygen toxicity made it unsafe for greater depths.

Finally, researchers such as Cousteau decided that filtered and purified compressed air was the best gas mixture to use in self-contained breathing devices. During World War II, around 1942-43, Jacques-Yves Cousteau and Emile Gagnan reworked a pressure regulator which Gagnan had initially developed to enable automobiles to run on vegetable oils due to acute shortage of petroleum during the war. The new regulator would send compressed air at the correct pressure to counteract the pressure put on the diver’s chest by the water. They called their device the ‘Aqua-lung’, and this has been the originator for the scuba diving gear of today.
