David Parker of AP Valves

We regret to announce that David Parker, Company Chairman and co-founder of AP has died.

He helped shape British diving over four decades, initially inventing and then manufacturing the AP Valve (the Angela Parker Valve).  This very simple and reliable breathing valve allowed divers to breathe the emergency air carried in the small ABLJ bottles fitted to the Fenzy and later the Buddy jackets.  Whilst it seems impossible to imagine now because almost every diver carries an alternative air source, ie an Octopus, this wasn't always the case. When the AP Valve was invented alternative air sources were just a pipe dream, hence this valve was much valued because it was an effective way of getting air to breathe in those first critical moments of an "out of air situation".

In 1972 David created the first Buddy buoyancy jacket and it was one of the first manufactured with a direct feed low pressure inflator.  Two years later in 1974 David again was an innovator producing polyurethane HF welded buoyancy jackets - the only sensible production technique that is used today for all BCs and Counterlungs.

He also invented the self-sealing surface marker buoy and was running the company when the Buddy Pacific, Arctic, Sea King, and Commando jackets were developed and first sold.

David Parker was a founding member of the North Warwicks Sub Aqua Club and was BSAC Instructor No.177.

In 2007, he was awarded a much deserved Lifetime Achievement Award by Diver Magazine for his lasting contribution to the diving industry. As of today's date, the only lifetime achievement award they have made.

He leaves behind an incredible legacy in the shape of AP Valves and Ambient Pressure Diving.

DEMA 2011; Hollis Gear acquires Recreational Rebreather design from VR Technology

Explorer Sport Rebreather, Hollis, CCR, DEMA 2011, Nitrox, PADI, Rebreather, Rosemary E Lunn, Rosemary Lunn, Roz Lunn, SCR, Type R, VR TechnologyHollis Gear is due to unveil a “game changer” in the world of Rebreather technology this afternoon at DEMA 2011.

Hollis Gear and VR Technology have teamed up to co-launch the Explorer Sport Rebreather. This is neither a fully closed circuit Rebreather nor a pure semi-closed system, but an intelligent hybrid that utilizes the best of both worlds. Apparently it's compact, lightweight and extremely easy to use.

The Explorer is unique in using a single gas; Nitrox, and is electronically controlled to achieve an optimal balance of PPO2 and dive time. Plug and Play absorbent cartridges, easy guided setup with “go or no go”, CO2 tracking, and 2 hour design duration should make this a dream for any recreational diver. It's also designed to meet the PADI 'Type R' requirement.
