The 25X delivers excellent cold water performance and reliability, only has port on one side for optimised twin, stage and sidemount diving and it is environmentally sealed.

    The 25X is machined from a single piece of nickel plated, marine brass for extra strength, features heat exchanger fins on the bottom of the body for additional cold water performance and it's compact design helps to keep it out of the way during the dive.
