Since our creation in 1953, members of the British Sub Aqua Club (BSAC) have been enthusiastic adopters of new diving equipment and procedures. Combined with our strong expeditionary and project focus, this has resulted in us being some of the first technical divers to visit iconic wrecks such as the HMS Prince of Wales/Repulse, HMS Victoria and RMS Egypt.
As a largely amateur organisation largely based on local clubs in the UK, individual BSAC technical divers can find it difficult to find others who share their passion. To address this, BSAC Technical centrally organises events such as technical try dives and training courses, all coordinated using our Facebook page. Until the pandemic we also organised a number of annual expeditions to places such as the world-famous wrecks off Malin Head, Donegal, which were very popular.
We have also seen technical diving becoming increasingly common in individual branches, leading to divers on the same boat and site using single cylinders, twinsets, sidemount, and CCRs. Some branches are fortunate enough to have very strong cadres of technical divers, and an excellent example is the Plymouth Sound Branch. In 2020, the club organised approximately 20 dives in the 60-80 meter/196-261 feet range mainly from their club RIBs and were also some of the very first divers to visit HMS Victory (1744) which lies in 78 metres of water in the middle of the English Channel.
BSAC Tech Webinars
BSAC is producing a series of webinars, many of which are of interest to Technical Divers. Non-members can access them by following the BSAC Technical Group Facebook page where they are advertised. Here are some of their recorded webinars:
Coming April 14 at 19:30 GMT:
The Relevance Of WWII Oxygen Experiments To Today’s Rebreather Divers by Paul Haynes. Driven by wartime operational requirements following a series of diving accidents–some of which were fatal–in the early 1940s, the UK Royal Navy undertook an extensive program of manned oxygen toxicity diving experiments to determine ‘safe’ oxygen exposure limits. Eight decades later, these experiments still stand today as the defining work in oxygen toxicity in humans. The presentation examines the key findings of these experiments and their relevance for today’s nitrox/rebreather diver. Anyone wanting to watch this talk needs to email firstname.lastname@example.org. All you need to do is send the email saying you want to attend, and you’ll receive the link on the day.
To support our branches in their technical diving, BSAC has long published Safe Diving guidance and created training, including some of the first CCR courses in Europe. In the last few years, we have been an important part of the highly successful worldwide collaboration to develop international standards (ISO) for rebreather training including the welcome inclusion of trimix on the earliest decompression course. Even before final publication, we are revising our own courses so that they will be compliant at the earliest possible opportunity and have already successfully trialed them.
As a broad church, BSAC Technical is proud to provide a forum for debates to improve Technical Diving, so we were particularly pleased to support Paul Haynes’ recent article and webinar on Mouthpiece Retaining Straps (MRS). Last year, BSAC also led the way by providing detailed information on the importance of managing gas density and were the first training agency to release gas density look-up tables which are now being built into our procedures.
In summary, BSAC Technical is a group of passionate divers who have come together to improve procedures and assist others to achieve technical skills; but mainly we want to do as much technical diving as possible! As the world situation improves, we’re very much looking forward to getting back into the water again.
