Why go tech? Motivations behind technical diving

In this essay, sports psychologist and technical diver Matt Jevon draws some parallels between the sport of technical diving and the sport of motorcycle racing, including attitudes and behaviors in regards to the inherent dangers and risks, sharing insights into our own nature as divers and adventurists.

Twilight Zone

The pressure builds, causing ears to pop as they equalise. The temperature drops and the light starts to fade. However, bubbles are not an issue for the researchers from the University of Oxford, as they descend in the waters off the Honduran island of Utila. Researching efficiently in the twilight zone requires rebreathers, and the summer of 2015 saw the first-ever expedition led by doctoral students using this technology.

Is There Still a Case for Open Circuit in Tech?

One thing about crystal ball gazing, it is a lot like looking down into the blue abyss while sitting in deco, with the sun’s rays streaming in and making a magical and inviting sight. To those who may not have experienced this yet, it is one of the most evocative and alluring sights that any diver—technical or sport—could ever see. It brings one closer to the water than one can explain in words.

In Defense of Diapers

Well, when using an adult diaper don’t hold it in, just relax. The first time you feel like you need to go, go!

As divers, we all learn very quickly that staying too long underwater can often bring about an urgent call of nature. A rush back to shore or back on to the boat is one of the first experiences for many new Open Water Divers, if not that ignominious feeling of having no choice but to make our wet suit slightly warmer for a short time.

TDI SDI Announces New UK and Ireland Regional Office

David Millin, Managing Director of Sea & Sea stated, “TDI is a legendary agency that UK divers and instructors have trusted for years to provide top notch training and quality materials. Sea & Sea is excited to be part of the continuing history”.

Brian Carney, President of International Training, acknowledged that the UK diving scene has an interesting history when it comes to TDI. The late Rob Palmer, a much respected cave explorer and a leading light in the fledgling technical diving community, helped set up TDI twenty years ago.

Are Rebreathers the Future of Diving?

A rebreather dive begins before you enter the water. You strap on the machine, put on your mask, or pinch your nose, and “pre-breathe” the unit for five minutes while monitoring the sensors and heads-up display (HUD) for any signs of trouble. It’s usually one of the last checklist items to complete before commencing the dive depending on the rebreather.

Exley on Mix

I first spoke with Sheck Exley in the summer of 1991. I had begun publishing aquaCORPS: The Journal for Technical Diving, a year earlier and I was working out of the office at Capt. Billy Dean’s dive shop in Key West, Florida, the first technical diving training center in the United States. “Technical diving”, a term we had just coined to describe this new style of diving, was just in its infancy.

Skills for Technical Diving

Learning to dive involves learning a new set of skills. Mask clearing, buoyancy control, regulator recovery and all the other skills that you learn on an open water course are essential for dealing with the underwater world. As a diver progresses through diving they learn additional skills such as using a drysuit, wreck diving or how to rescue their buddy. With technical diving there are again some new skills that need to be learnt.
