First Stage:

Auto Closure Device (ACD) – keeps corrosive water out of the first stage inlet by automatically closing as the Legend is removed from the cylinder valve
This prevents internal lubrication from washing away
Safer for elevated percentages of oxygen
Unique over-balanced, diaphragm design results in superior performance at depth
2 HP ports and 4 MP ports are angled for optimum hose routing
An environmental dry system keeps water out of the main spring chamber thus preventing ice buildup and keeping silt and contamination out
Available in your choice of yoke or DIN connectors
Compatible with up to 40% O2 right out of the box
Second Stage:

Pneumatically-balanced second stage results in smooth, easy breathing
A venturi switch helps prevent free-flow at the surface and when the regulator is out of the diver’s mouth
The opening effort is preset in a fixed position so the diver doesn’t have to worry about adjusting the regulator during the dive
The Comfo-Bite mouthpiece virtually eliminates jaw-fatigue
Heat exchanger (patented) which surrounds the valve mechanism, dissipates the cold caused by gas expansion while drawing in the warmth of the ambient water
The ergonomic exhaust tee channels the exhaust bubbles out of your field of vision. The design also contributes to a reduction in exhalation effort
Attached to a 29ʺ braided Aqua Flex hose. These hoses are lightweight and extremely pliable which eliminates any tugging on the mouthpiece
