"What dive charter companies out there are TRUE supporters of technical diving? By this I mean that they don't just say that they are 'tech' or 'CCR' friendly. They really provide the products, services and support needed by this market."

Here is the criteria:

  • The company states whether the customer wanting to do a tech dive needs to buy a sole charter, or a customer can walk in and go for a tech dive
  • The company has tech gear for hire - twin / double manifolded cylinders, rigged stage tanks, sorb, etc
  • The company pumps helium, oxygen, etc and can boost fills
  • The staff are fully capable of supporting tech divers, ie providing guiding services

If you know a dive company who can offer at least two out of the four criteria listed above, please email Pete Mesley.

He would really appreciate your feedback and input on this.

 

John Dalla-Zuanna Receives OZTek 2015 Outstanding Achievement Award

OZTek 2015 Technical Diver of the Year, OZTek 2015 Industry Recognition Award, OZTek 2015 Outstanding Achievement Award, OZTek 2015 Media Excellence Award, John Dalla-Zuanna, Richard Vevers, Richard Evans, Lance Robb. OZTek 2015 Award Winners, Rosemary E Lunn, Roz Lunn, The Underwater Marketing Company, The OZTek Awards celebrate the achievements and endeavours of Australia's leading Divers and Dive Industry personnel - the people who have helped push the boundaries of knowledge and exploration in the field of advanced and technical diving.

On Sunday 15th March 2015, during the Gala Award Ceremony, previous OZTEk award winner Dr Richard 'Harry' Harris announced OZTek's 2015 Outstanding Achievement Award. This is what Harry had to say to packed audience of advanced and technical diving movers and shakers.

"It is an enormous honour to be asked by the OZTek Organisers to present this very well deserved award to a close friend, a wonderful dive budy, a mentor and a constant voice of reason in the mad world of technical diving!

I would like to break with tradition and ask this man - John Dalla-Zuanna - to come and join me up here, whilst I tell you why he is such a special guy in this great sport of ours.

At the cheeky young age of just 58, JDZ is truly a veteran of the sport of cave and technical diving. Cave diving in Australia started pretty much at the time JDZ started cave diving, so it is impossible to consider one without the other. Around the time the CDAA became incorporated in 1973, JDZ started visiting the Mount Gambier area. He cut a fine figure in Piccaninnie Ponds with his Moray suit! He became qualified in 1975 as member #256 and from that time on was inspired by the sport. A trip in the late 70's to Florida to meet Sheck Exlley, Wes Skiles and Woody Jasper quickly led to adopting sidemount diving, and feeling the thrill of laying line in virgin passage.

Thus the passion was born and returned to Australia and began teaching both open water and cave diving. He has reached the highest levels of recreational and cave diving instructor. And, as a long time FAUI instructor, a PADI Course Director and CDAA Advanced Cave instructor, countless students have come under his thoughtful and methodical influence. The CDAA has benefited enormously from John's vision for cave diving, and he has filled a voluntary position with that organisation in some form or another almost continuously. Ken Smith always said that he used to think cave diving politics were a matter of life and death, and now he realises it is much more serious! JDZ has been a calming influence on all factions of the CDAA for many yearss and is unique in that he is respected and heard by all sides.

I met John at OZTek in, I think, 2003. We had been exchanging emails for awhile and I was about to leave to live in Vanuatu. John had built a rebreather heads up display from an LED light and a mobile phone vibrating motor! He generously gave me this device to put onto my KISS rebreather, which considerably enhanced the safety of my cave exploration at the the time.

After my stint in Vanuatu JDZ was one of the instructors on my penetration course and we struck up a real friendship underscored by our passion for caves, rebreathers and exploration. John had dived in so many caves around the world and along with guys like Paul Hosie, Craig Challen and Ken Smith, I quickly found a group of experienced cave divers who mentored me into the world of exploration and expedition diving. I am sure John has had a major impact on many other peoples' lives, the way he has influenced mine.

JDZ's ingenuity goes way back. He built a radio detection device called 'the Thumper' which played no small part in the mapping of Mount Gambier's showpiece, 'Tank Cave'. John was an early adopter of closed circuit rebreathers, and along with Tubby McKenzie the early leaky valve CCR Dolphin was born and dived to 85 metres on the Bayonet in the ships graveyard in Victoria. It was this creation that caught my eye and got me into rebreathers in 2002.

John the inventor became an indispensable part of the Wetmules team. (Moto: Lurching from crisis to crisis). His lithium scooter batteries propelled Craig Challen and I to the end of Cocklebiddy in 2008, where Craig added new line to the end of the cave. They also now famously caused the fire which burnt my car to the ground on the way home! His early 12 volt heated undergarments kept us warm in the Pearse Resurgence and his wonderful pasta kept us fed.

Dr 'Harry' Harris contemplating the fact that his beloved Mk15.5 rebreather was now a blackened blob inside the burnt out shell of his Nissan Patrol. (Along with all his other diving equipment, camera system, camping equipment, laptop and clothing). Harry was his way home from a two week cave diving trip to Australia's famous Cocklebiddy Cave in summer 2008, when he spotted smoke in the rear view mirror. 10 minutes after pulling over, everything was destroyed by fire.

John is a regular ocean and wreck diver. He has numerous sub 100 metre / 328 feet wreck dives to his credit and continues to teach young divers open water diving through the La Trobe university club, sharing his passion for all things aquatic. His huge passion right now is the 3D mapping of cave using a combination of video and gaming technology, and in this area he is becoming a world leader. I hope many of you got to see his talk on this today. As the current Site Director of CDAA he shows no sign of letting up, and I look foward to sharing many more dives with this wonderful friend and great ambassador for the sport of technical diving.

Auckland Based Diver? Take Part In A CO2 Prebreathe Study This July

Dr Simon Mitchell and Dr Neal Pollock will be presenting their research at EUROTEK.2014

Are you an Auckland based diver, or live near Auckland, New Zealand? Are you available on Saturday 19th or Sunday 20th July 2014? Do you dive a rebreather or are thinking of becoming a rebreather diver? If you answer 'yes' to these questions, Dr Simon Mitchell and Dr Neal Pollock need your help. They are conducting a Carbon Dioxide (CO2) Prebreathe Study and need volunteers to assist in this incredibly useful research.

We are delighted to report that the findings from this study will be announced at EUROTEK.2014 in September.

What is the purpose of this research?

Rebreathers which recycle exhaled gas after removing carbon dioxide (CO2) are becoming increasingly popular in recreational diving because they offer advantages such as the conservation of breathing gas. However, they are more complex than normal scuba equipment, and there is potential for operator error in their use. These errors may lead to accidents and death. Several of these potential operator errors relate to the use of the CO2 absorbent (or the CO2 “scrubber”). If there is failure of CO2 removal from the expired breath, the diver will re-inhale CO2 and this may result in hypercapnia (commonly referred to as CO2 toxicity). Rebreather divers are taught about this during their rebreather dive training. CO2 toxicity may cause progressive shortness of breath, headache, anxiety, panic, and ultimately unconsciousness. In addition, CO2 toxicity enhances the adverse effects or toxicity of other gases such as nitrogen and oxygen. There have been many deaths during the use of rebreathers in which CO2 toxicity is thought to have contributed, though this is often difficult to prove.

The absorbent material used in CO2 scrubbers must be replaced periodically. Related errors include failing to replace the absorbent material, incorrect packing of the absorbent material into the scrubber canister, and incorrect installation of the canister in the rebreather (or forgetting to install it entirely). Most rebreather units do not monitor CO2, and so rebreather divers are taught to conduct a 5 minute “pre-breathe” of their unit just before entering the water. A prebreathe involves preparing the unit for diving, and then sitting quietly breathing on the rebreather loop. If the CO2 scrubber is absent or faulty the diver will rebreathe CO2 and, in theory, should notice the early symptoms of CO2 toxicity such as shortness of breath or headache.

Divers assume that symptoms of CO2 toxicity will occur reliably and be noted during a 5 minute prebreathe. However, this has never been formally tested. This study aims to measure the proportion of subjects who can identify the absence of an effective scrubber during a 5 minute prebreathe on a rebreather circuit. The detection of a partial scrubber failure may also be evaluated.

If you want to be part of this important study please email Pete Mesley as soon as possible to get booked in. You will be need for no more than 2 hours during the course of the weekend.

 

Rescue of an unconscious diver from depth: the new UHMS guidelines

This is Professor Simon J Mitchell. Simon gave a presentation at EUROTEK.2012 entitled “Rescue of an unconscious diver from depth: the new UHMS guidelines”.

Dr Simon Mitchell talking to EUROTEK.2012

This was probably one of the most important presentations delivered at EUROTEK.2012 and it was the first time this talk was given to a European audience.

Aspects of the correct course of action on finding an unconscious diver underwater have been debated on various internet forums;

- Should you try to replace the regulator?
- Should you wait until a seizure is finished before ascending?
- What procedures should be in place for a rebreather diver?
- Should you try to complete some decompression on a decompression dive?
- Should you try rescue breaths in water at the surface?

We are delighted that permission has now been granted by the UHMS Journal Editor to allow the recreational and technical diving community to access this valuable resource.

The Undersea and Hyperbaric Medical Society (UHMS) is an international, non-profit organization serving over 2,400 members from more than 50 countries. The UHMS is a primary source of scientific information for diving and hyperbaric medicine physiology worldwide. You can help support them by becoming a member and you also get access to the journals.
