This regulator is also equipped with a VIVA (Vacuum Failure Indicator) system, which provides a visual and audible alert in case of a free dive or air leak. The DC-7 also features a purge button on the second stage, allowing divers to clear their regulator easily, ensuring a smooth start to each dive.
The Hollis DC-7 Yoke Regulator is a robust and reliable piece of diving equipment, made with materials that can withstand the harsh underwater environment. It is easy to service and maintain, ensuring its longevity and continued performance. Overall, the DC-7 is an excellent choice for recreational and technical divers who prioritize safety, comfort, and performance.
