Latest UHMS Guidelines On Recovering An Unconcious Diver From Depth To Be Presented At TEKDiveUSA 2014



TEKDiveUSA – the inaugural North American biennial advanced and technical diving conference – will be launched in Miami this Spring. It is being held on Saturday 17th and Sunday 18th May 2014, and is similar in approach to both EUROTEK and OZTek.

It has been many years since America held a technical diving conference, and it is time that the USA had its own homegrown event. The focus of TEKDiveUSA is to entertain whilst furthering the educational aspects of advanced and technical diving. It also gives people who are out there doing exciting projects a platform to share their story with others.

During the weekend forty different talks and useful workshops will cover many aspects of diving; from wreck, cave and physiology through to technique, safety and imaging. Leading experts are flying in from all over the globe to speak at TEKDiveUSA 2014. It promises to be a truly inspirational diving conference.

Rosemary E Lunn, co-organiser of TEKDiveUSA stated, “I am delighted to say that we have got a number of top drawer speakers on board. Associate Professor Simon J Mitchell (Head of Anaesthesiology at the University of Auckland), Richard Lundgen (deep wreck explorer), Cristina Zenato (shark diving professional and cave explorer), Dr John Clarke (Navy Experimental Diving Unit) and Dr Neal W Pollock (research physiologist) have already said, ‘yes we’d love to come and talk, Roz.’ With the plethora of talks planned there will be something that will appeal to every hungry diver wanting to know more.”

“This conference will also be useful to dive professionals, managers and dive center owners. You certainly do not need to be a hard core tekkie to visit TEKDiveUSA, just someone who wants or needs to learn more about diving.

“Probably one of the most important presentations to be delivered during the weekend will be ‘Rescue of an unconscious diver from depth: the new UHMS Diving Committee Guidelines’. This is the first time this talk has been to a North American audience. If you are an advanced or technical diver, instructor, a military, commercial, scientific, public safety or media diver, the presentation is pertinent to you.

“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?

“The Diving Committee of the Undersea and Hyperbaric Medical Society recently completed and published a two-year project to review these questions. Associate Professor Simon J Mitchell will outline the committee’s findings, and the arguments supporting them.

“This is the perfect opportunity to get the entire community engaged – regardless of agency affiliation or philosophy – together as one unified group. It will be great to see everyone sharing experiences and be motivated by, and from each other. Foremost explorers and divers are booking in. If you want to hear about their adventures and expand your diving horizons, tickets are on sale. Secure your weekend pass (US$129.95) now via”

Fourth Element announce Tech Fins inspired by whale tail



A classic vented dive fin, engineered by nature and redesigned to maximise performance.

Fourth Element’s new Tech Fins have taken inspiration from nature and evolution to optimise efficiency. The turbulence disruptors on the top of the blade work in the same way as the nodules of the leading edge of a humpback whale fin, which disrupt the water as they move through it. The resulting turbulence enables the whale to swim with more efficiency. Fourth Element has adopted this evolutionary concept to improve the performance of this classic fin.

Utilising natural rubber in a unique density gradient, the dive fin delivers an ultra- comfortable foot pocket combined with optimised stiffness for finning performance.

The vented design allows water to flow along the blade reducing drag and fatigue, whilst the stiffening rails and ribs ensure that the blade of the fin is driven through the water to maximise the return on effort.

The Tech Fins, with a slightly negative buoyancy characteristic, were developed with technical divers in mind but are suitable for all levels of diver looking for a high-performance rubber fin. The wider blade gives manoeuvrability without compromising the power, while the shorter length improves agility and makes stowing the fins for transport more convenient. Spring straps with comfortable heel pads keep the feet securely held in place. These straps can be removed and changed easily with everyday tools if required.

The Tech Fins are supplied with a hanging/carrying strap and a marine quality bolt snap which may be used to attach them to a bcd or harness for carrying, leaving both hands free for climbing ladders or carrying other gear.

The natural rubber material of this fin is extremely durable, and all components are recyclable at end of life.

The Tech Fins are available in M, L, XL and XXL. These fins will fit sizes 4 (US5) to 14 (US15) and come in Black, Grey or Aqua.

  • Stainless steel spring strap
  • Soft foot pocket
  • Hydro-flow vents
  • Turbulence disruptors
  • Strengthening ribs
