The new Mistral is a modern version of the original double hose regulator invented by Aqua Lung founder Jacques Cousteau and Emille Gagnan in 1943.

Modern single hose regulators release exhalation bubbles directly from the mouthpiece in front of the diver.  These bubbles can obstruct the diver's view and have long been a complaint with underwater photographers.  Double hose regulators have the unique advantage of releasing the diver's exhaust bubbles behind the diver's head and not obstructing the field of vision.  Double hose regulators also perform very well in icy waters where single hose designs could freeze up and quit working.  This is because the diver's humid exhalation doesn't pass over the moving parts of the regulator, which could cause ice crystals to form.

The Mistral offers all the benefits of the original double hose regulators, combined with the developments and refinements of modern regulator technology.  Incorporating a time proven dry sealed first stage, a unique completely sealed second stage, a high pressure port and multiple low pressure ports, the Mistral offers all the benefits and reliability of modern regulators.  The Aqua Lung Mistral is also the first modern double hose regulator to pass the European EN 250 breathing performance tests.

The Mistral's unique double hose design will appeal to underwater photographers, videographers, ice divers, commercial divers, military divers, search and rescue divers, scientific divers, and anybody nostalgic for the 'good ol' diving days.
