Zeagle Onyx CW – 1st Stage Only


Easy breathing high performing cold water regulator.

The Onyx CW, a 2013 Scubalab Testers Choice regulator, is the sealed version of the 2011 Scubalab Testers Choice regulator, the Onyx. With the same attractive finish and outstanding performance as the Onyx regulator, the Onyx CW fills the need for those that find themselves in cooler water.

The internal structure allows direct airflow through the 1st stage, providing lower turbulence for outstanding performance.
