Apeks XL4 Second Stage Regulator

The Apeks XL4 Second Stage is compact and lightweight regulator suitable all diving environments. It even performs well in cold water. Its design and low weight reduce jaw fatigue. This makes long dives more comfortable. 

The XL4 Second Stage comes with a Comfobite mouthpiece that features a unique bridge. It fits across the upper palate. Therefore, it needs no bite pressure to stay in place. A reusable mouthpiece clip simplifies field changes.
