HOLLIS 500SE 2ND STAGE REGULATOR
OLD SCHOOL. NEW TECH.
The 500SE utilizes a servo-controlled valve to provide precision airflow and unparalleled performance for both air and trimix divers in a side exhaust configuration. To achieve this, we have perfected the original "lever-servo valve" we designed 35 years ago. Overbalanced diaphragm
the first stage also provides ideal hose routing for both back mount and
side mount users and optimum performance regardless of depth.
