Rebreather Divers Grateful For Henderson’s List

At the end of May 2017 AP Diving’s Managing Director – Martin Parker – issued a statement on the Inspiration List.

“Gordon Henderson is retiring his Inspiration Users List after 19 years. I don’t think this milestone should pass without acknowledging the role of Gordon’s Inspiration List for CCRs generally: It has been a fundamental part of the way the sport diving world has learned about closed circuit rebreathers, procedures and rebreather safety.”

Gordon Henderson was an early adopter of the Inspiration Rebreather and a gifted IT specialist. When he placed an order for the “just launched” Inspo in 1998, Henderson immediately recognised the need for Inspiration owners to be able to communicate freely, and set up the Inspiration List using his Drogon email system. (Social media didn’t exist at the time and forums were pretty basic).

The resulting Inspiration List provided certified AP rebreather users with immediate multi-way communication and the ability to discuss issues, and share experiences with other CCR divers because “no knowledge or a little knowledge can kill you”.

“Why we don’t use Lithium Hydroxide, …..the idea for monitoring the thermal process in the scrubber came from list member discussions, ….understanding the effect of depth on the scrubber, …best decompression practices, ….best gas choices are just some of the topics that were put to bed.”

“As a new Inspo diver (15 months now), lemme [sic] register my regards and gratitude to Gordon for doing this good work. A list like this is critical to safe, independent customer development and education, and it’s good to see that the factory agrees.”
Ken Blakely

This forum has proven to be the single most valuable education tool for the both of us to learn to dive more safely and knowledgeably. Time and again real nuggets of information from many contributors have enable us to learn more about our breathers and diving in general that we would not have otherwise learned.”

Martin Parker also stated that if it wasn’t for Gordon’s involvement, the Inspiration List would have been dropped.

“I realised that quite a few of the subscribers enjoy this form of communication and if there is something important for the factory to say, it’s a good way of reaching people quickly.” Martin Parker

The Inspiration List also inspired other divers to set up valuable resources, including Jan Willem Bech’s “The Rebreather Site.

We are pleased to report that Andrew Last has kindly taken up the Inspiration List mantle.

Thank you Gordon for your exceptional service. It has been appreciated by so many CCR divers.

I’ll leave the last word to wreck explorer Geraint Ffoulkes-Jones.

“The true legacy of all your excellent work just cannot be measured, because it is the number of lives your valuable Inspo and general CCR information sharing source has saved over countless years, and thankfully we will never know the true extent.”

 

 

A New Option For Carrying Dive Plan Data

The phrase “plan the dive, dive the plan” was coined Hal Watts, founder of PSAI. (He was also the one to name an alternative air source ‘an octopus’, but that’s another story.)

Let’s face it, the fundamentals of dive planning remain the same for all divers, a process that every diver should follow. However, when it comes to recording your proposed plan, what do you do? It can be quite simple data or something far more complex, depending on what level of dive you have planned for.

Mixed gas training in Scapa Flow, March 1999

I wish that ‘Deco-Decals‘ has been in existence in March 1999 during my trimix training. I can vividly remember sitting in the cabin of MV Karin – a Scapa Flow liveaboard – with a roll of masking tape, and very precisely covering my wrist slate with strips of it. Once this was evenly applied I would then carefully draw a specific grid in biro. Finally I would take my time to write out my dive schedule and two bailout tables. It would typically take me about 30 minutes to plan my dive and get my slate ready for a dive. Whilst I found the process quite theraputic, the task was a bit of a time thief, and I would lose chunks of my day complying with best practice in dive planning.

Today there is a better option for both OC and CCR advanced and technical divers to record their proposed dive – along with the various bail out options – thanks to a collaboration between Huw Singer, Bristol Channel Diving Services, Neal Brock, Deco-Decals, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, XRay Mag, X-Ray MagazineHuw Singer and Brit based Bristol Channel Diving Services. The team designed and developed a range of self-adhesive, ‘traffic light’ colour-coded slate stickers called ‘Deco-Decals’. They should fit pretty much every scuba-diving wrist slate available (Size: 200mm x 118mm).

Green – the dive is going to plan.

Amber – depth or time has been exceed and adjustments should be made, ie next depth, next time.

Red – there is an issue that requires immediate action, ie loss of decompression gas, or bailout is needed.

We all know that colour is absorbed at depth, so what is the point of colour coding each decal? In low light conditions the diver will use a light to read their slate – and in blue water there will be a visual difference, albeit subtle. The significance of the colour coding also makes the students think beyond the immediate dive plan and understand the implications of properly planning for set scenarios, in addition to the original dive plan.

Each Deco-Decal is logically laid out, in an accessible format for training scenarios or every day diving up to 70 metre / 230 feet diving, and is available in both metric and imperial. (There is also a V2 version of Deco-Decal dive planning set which is printed slightly larger, apparently making it easier to read underwater for those with slightly older eyes.)

The green slate has a two useful key way points to prompt you where you need to turn your dive – gas pressure or time. Plus you can see the gas mixtures you are carrying, both back gas and deco gas.

The reusable decals are varnished and durable, and you simply write on them using an ultra-fine tipped waterproof marker. Once you have completed your dive and want to input fresh data, just wipe the decal clean with a ‘Magic Sponge’ / ‘Magic Eraser’ or similar product. After multiple use (10+ dives) you can replace a decal by peeling it off cleanly, leaving little, if any, adhesive residue.
