Bonassi Eolo regulator (2nd stage) with hose has excellent cold-water performance. This scuba regulator operates with an anti-freeze dry seal system.
Eolo diving regulator comes with a venturi control lever with Dive/Pre-Dive mode. This switch or knob alters the airflow inside the regulator, making breathing easier on the surface and underwater. The “off” setting helps avoid free-flows at the surface.
