The Keppel II second stage incorporates both style and function and is the ideal choice for the most rugged of diving conditions, making it a new ‘best in class’. The small, ABS polycarbonate housing makes it tough and light, reducing overall jaw fatigue during diving. The strategically engineered shape and firmness of the purge not only look good but helps prevent diaphragm surge when swimming into a current. Pre-positioned front cover ring holes ensure ease of serviceability after heavy use and the second stage incorporates a downstream demand lever valve. This mechanism provides high airflow and smooth, easy breathing. 40% Nitrox compatible out of the box and is included in the Oceanpro Free Parts for Life program.
