Hollis 500SE

Old School. New Tech.┬áThe new 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 first stage also provides ideal hose routing for both backmount and sidemount users and optimum performance regardless of depth.

Prices vary. Please Contact Us for more information and other models not listed.
