  • Description

    Hollis DC7 500SE regulator is Old School -with New Tech! The new 500SE utilises 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 first stage also provides ideal hose routing for both backmount and sidemount users and optimum performance regardless of depth.
