The LEG3ND Octopus is the perfect compliment to the Legend regulator family. The high-visibility yellow color makes it easy to find when it's needed most, while the pneumatically-balanced second stage results in smooth, easy breathing. A venturi switch helps prevent free-flow at the surface. The opening effort is pre-set in a fixed position so the diver doesn't have to worry about adjusting the regulator during the dive. Excellent cold-water performance due to highly efficient heat exchanger surrounding the valve.
