Today ‘technical diving’ is a common phrase and nothing is really thought too much about it … today nitrox is standard, rebreathers are accepted everywhere and growing in numbers (including recreational rebreathers), and side mount is a popular dive configuration.

But was it always like this? How did ‘technical’ come about? It’s never been documented in Australia …. Until now!

OZTek2017 presents a unique photographic exhibit celebrating the people, projects and technologies behind the ‘Technical Diving Revolution’ (1986-199x).

Curated by aquaCORPS Journal founder Michael Menduno, Pushing The Envelope will feature nearly 300 images, maps, tables and quotes (circa 1986-199x) from the early days of technical diving.

Some of the expeditions included are the Andrea Doria, USS Atlanta, RMS Britannic, Cocklebiddy, Diepolder, Edmund Fitzgerald, RMS Lusitania, Nacimiento Manté, USS Monitor, RMS Niagara, Pierce Resurgence, The Shaft, Tank Cave, U-869 (‘U-Who’), Yucatan, Wakulla Springs, and Zacatón.

On display are early tech trimix tables including the first Australian trimix tables created by David Doolette for Chris Brown’s 1993 expedition and Jim Bowden’s 1000-ft Zacatón table; a way-back with ex-NOAA director Dick Rutkowski’s original nitrox training facility, and the first US technical diving training centre, Key West Diver, Key West, FL.

The exhibit also includes pictures of the first mix gas fill stations, early rebreather prototypes, a look into early tech diving fatalities and memorabilia including the Cave Diving Association of Australia (CDAA)’s ban on mixed gas diving in the mid-nineties.

In addition, Pushing The Envelope offers up tributes to tech’s patron saint Sheck Exley, u/w photographer Wes Skiles and decompression guru Dr. RW ‘Bill’ Hamilton.

GET READY TO MIX IT UP!
