The Nitrox Recreational Mode will be available free of charge, as a firmware update, on all Shearwater Petrels from mid to late April 2014.

We have been advised that this new Nitrox mode is clearer and easier to use than ever before. The new mode offers optional safety stops, obvious warnings and plenty of customisation, and will make the Petrel a useful computer for air and Enriched Air Nitrox (EANx) diving. When divers are ready to take their diving to the next level, the Petrel will support their trimix and rebreather requirements.

Key Features of this new mode include:

  • Big, Clear Displays
  • Optional Safety Stops
  • Decompression when you need it
  • Configurable Bottom Row
  • No-Decompression Limit Planner
  • Simple Menu System

Apparently this new recreational mode has simple settings that allow the diver to use three air or nitrox breathing gas mixtures, whilst giving a greater emphasis on the no-decompression limits (NDL). A bar graph display will turn from green to red as the diver approaches their NDL. In addition a 3 minute countdown safety stop will start when the diver hits 6 metres / 20 feet on their ascent. If the Petrel goes into a mandatory decompression situation, the display turns red and displays, “DECO STOP” with the depth and time at that stop.

Do you want to get trained by a renowned diving and environmental physiologist? Dr Neal W Pollock will be heading up the DAN 75th Diving and Hyperbaric Medicine Course in May. This six-day course will be held at Little Cayman Beach Resort in Little Cayman from Saturday 3rd to Saturday 10th May 2014. The course is designed primarily for physicians. It may be of value to emergency medical personnel, paramedics, nurses and other professionals with interest in diving as well.

The program delivers a range of topics to orient participants to the state of the art of diving safety, diving medicine, hyperbaric medicine and environmental physiology. Classroom time includes lectures and interactive case studies sessions.

Presentation topics include:

  • Medical and physical fitness to dive
  • Diving safety - issues and current research
  • Hyperbaric medicine - applications, protocols and mechanisms
  • Decompression physiology and pathophysiology
  • Diving injuries and management
  • Considerations for thermal stress, altitude exposure, freediving and special populations
  • Controversies in diving medicine

Santi Launch Their 'Ladies First' Drysuit

Santi Ladys First Drysuit_Rosemary E Lunn_Roz Lunn_The Underwater Marketing Company_X-Ray Magazine_Jill Heinerth_Becky Kagan Schott_thermal stress_Dr Neal W Pollock_John KendallDid you know that International Women's Day is annually marked on 8th March? Me neither. Why do I mention this? Santi has chosen this day to launch their new 'Ladies First' range of dry and undersuits.

A number of suit manufacturers have been producing a ladies cut drysuit for awhile. Santi has now joined their ranks with the launch of their 'Ladies First' drysuit. This membrane suit is based on the current Santi E.Motion drysuit. It is constructed from an ultra flexible material and is ultra lightweight. I saw this suit at the 2014 Dusseldorf Boot Show and believe it to weight approximately 4kg. The 'Ladies First' suit has a number of nice features that come as standard. A warm neck collar, bib and braces / suspenders, a choice of seals (latex, neoprene and silicone), and two cargo pockets on the thighs.

The pockets are slightly narrower cut to ensure a more optimal fit on a petite leg. Both pockets benefit from a metal D-ring and a couple of bungee loops. If you have never used bungee loops before, they are a godsend when you are rooting through your pockets looking for a specific item. It means that provided you have clipped various items to the bungee loop, you can turf your pockets out underwater and you don't lose a piece of kit. In addition one of the pockets has an external zipped pocket on the outside of the flap and this is handy for stashing a Trilobite cutting tool.

Front zipped suits are always a better option for ladies because the tailoring can be more precise. Generally the biggest bit that a lady has to get into a drysuit is their good child bearing hips, unlike a man who traditionally has broad shoulders. Ladies tend to have smaller shoulders compared to their hips, therefore a front donning suit is normally the preferred choice because you achieve a better cut / fit. The radical thing that Santi has done on this suit is switch the front plastic T zip route, and I suspect that it won't be long before the other manufacturers do the same thing. On the 'Ladies First' suit it runs from the top right shoulder down to the left hip instead of the usual route of top left shoulder to bottom right hip. Why is this so special? If the front zip is routed in the traditional way on a petite female, the manufacturer can struggle to get the shoulder dump in the right location because the zip can be in the way. By simply switching sides, Santi can ensure the shoulder dump is located in the best place, what ever size of female.

Overall this is quite an attractive feminine suit without being girly. Interestingly the colour scheme - black with fuchsia highlights - is strongly reminiscent of Apeks Aqua Lung's 'Twilight' highlight colour in their ladies 'Details' range. Purple really is the new pink. If you don't fancy fuchsia, Santi also offers the choice of black with lemon highlights and black with black highlights. The complete package comes in a practical bag and you also get a limited edition woolly hat. I am certainly curious to see what this suit dives like.

Scuba Schools International (SSI), a premier education and business support organisation, is pleased to announce the appointment of Adam Wood as SSI Technical Training Director.

Adam Wood, SSI, Scuba Schools International, Steve Newman, Corrie Harris, technical diving instructor, Doug McNeese, Robert Stoss, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, Divemaster Scuba Nottingham, Tech XR, XR, TXR As one of the new breed of young dive professionals, Adam is striving to raise the bar of technical diving and challenge old perceptions and philosophies to make exceptional divers and instructors. Adam's passion is teaching, passing on knowledge & skills in Technical, Sidemount and Closed Circuit Rebreathers, both at user, instructor and instructor trainer level. He is focused on making diving aspirational, cool and exciting with the goal attracting a new divers and retaining old ones.

Adam owns one of the UK's largest certifying dive centres and is one of a select group of SSI Recreational, Technical and CCR Instructor Trainers. He was also a contributing editor to the new XR & TXR Technical & Technical CCR Materials for SSI. As one of the hardest working people in diving you can find Adam teaching almost every day either in one of the UK's satellite centres or in worldwide destinations.

"Having seen the benefits the SSI system brings to the dive centre I now want to blur the lines between recreational and technical diving whilst making the higher end of technical diving more extreme and safer than ever!" "I have supported the production of the recent XR and TXR materials and am underway with the next new releases – you better be excited!" commented Adam Wood, SSI Technical Training Director.

Robert Stoss, SSI President said "It is great to have Adam on board, we have been watching him grow in the technical diving auditorium and this is an excellent opportunity for us both, he knows how to structure new technical programs and understands how they will be implemented within the successful dive centre. He has a number of great projects planned for 2014 and with the new opportunities available within SSI we can take technical diving to the next level."

Adam has been lucky to be invited to be involved in some exciting projects around the world. More recently he has been contracted to work with and train the BBC Natural History unit, acting as trainer, technical advisor and dive supervisor.

TeXpediationR is a project Adam hopes will flourish, allowing all divers to participate in Expedition diving at their own level. Adam has acted on screen, been an aid to under water filming and provided logistical and technical support for worldwide projects, most recently he has been filming with the BBC in North Carolina inside the wreck of the Aeolus with over 200 Sand Tiger sharks.

Remember, SSI is not just a certification agency. WE ARE YOUR PARTNER IN BUSINESS! What we offer around the world is way ahead of even much larger industries. If you want to break the bonds that hold you back from reaching your potential, either email us or visit our website.
