The Aqua Lung Legend Supreme is a cold water rated environmentally sealed regulator with additional cold water features. The new Aqua Lung Legend is smaller & lighter than the old model, providing a more comfortable dive. The balanced diaphragm first stage offers exceptional performance at any depth, cylinder pressure or condition & the added benefit of the environmental seal helps prevent cold conditions from affecting the first stage reliability. The Legend Supreme second stage is fitted with additional cold water measures including heat exchangers & a lip shield (which can be easily removed) but most importantly it has been specially adjusted to resist freezing. A venturi switch provides control of freeflow on the surface & whether the regulator isn't in use. A redesigned exhaust deflector provides better dispersion & easier exhalation.
