Present Ideas For Divers: Oxygen Measurement For Divers by John Lamb

Oxygen Measurement For Divers, rebreather divers, oxygen sensors, John Lamb, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, fuel limited sensors, storage of sensors, oxygen sensors, Paul Toomer, Mark Powell, Jill Heinerth, CCR safetyDo you have a rebreather diver in your life that you are particularly fond of?

Are you stuck for a present idea? If they don’t already possess a copy of John Lamb’s latest book, then why not pick them up a copy. It will help keep them safe(r) and provide them with accurate information on oxygen sensors.

“John Lamb’s book, ‘Oxygen Measurement For Divers’ is exactly what we have been waiting for. This book is a must read for any diver using any form of oxygen analyser, whether it is a simple oxygen analyser or in a complex rebreather.”
– Paul Toomer, Director of Diver Training, RAID

There are quite a lot of myths and misconceptions about oxygen sensors, hence earlier this year John Lamb published ‘Oxygen Measurement For Divers’. It is stuffed full of nuggets of information that every rebreather diver needs.

This book has been designed for divers to pick it up and dip into it. To check information. To look up answers.

It has achieved the happy balance of having a good technical aspect whilst remaining useful.

“This is an invaluable resource and should be compulsory reading for any rebreather diver.”
– Mark Powell, SDI / TDI / ERDI Training Advisory Panel

The explanations and illustrations are very clear and, even when describing complex principles, are structured in a very understandable way. Everything is covered from current limitation behaviour to best management practices for storage.

Lamb succinctly covers key topics, explaining in plain English the reasons for sensor failure:

  • the effects of temperature, humidity and pressure
  • sensor accuracy and stability
  • testing sensors
  • Do’s and Don’ts
  • how to determine the end of a life of a sensor
  • advice for looking after your sensors

“If you want to break through the mire of misinformation and be better informed about diving safety, this is a must-read book.”
– Jill Heinerth, explorer

‘Oxygen Measurement for Divers’ can be purchased in two formats. As a paperback, direct from Vandagraph for £15.00. Or, as a Kindle book for £7.50

 

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.”
