The Hollis 500SE DC7 Regulator offers smooth breathing with performance and comfort. This regulator easily delivers air at depths deeper than 150 ft (45m) thanks to the overbalanced DC7 first stage that provides greater intermediate pressure to the 500SE second stage. A servo-controlled valve, with a side exhaust, provides optimum airflow to deliver superior gas output even under extreme conditions. Set it up on your sidemount or backmount BCDs with the inline scuba tank connection that has left and right positioning. Choose between the DIN or Yoke regulator for recreational or technical dive. Whether you’re diving in the Caribbean, the Great Lakes or the Atlantic Ocean, the Hollis 500SE DC7 will keep you breathing.
