Apeks DB4+ 1st Stage Dive Regulator

Introducing the latest innovation in scuba diving equipment, the high-pressure ports and compact machined first stage of the Apeks DS4 platform make it a top choice for any diving enthusiast. The over-moulded first-stage endcap and environmental diaphragm prevent ice build-up and protect the first stage from impact damage, ensuring optimal performance even in extreme conditions. The large surface area heat exchanger diaphragm clamp helps increase gas temperature inside the first stage, improving cold water performance. With a unique over-balanced diaphragm design, this regulator allows for superior performance at depth. As the diver descends, the over-balancing feature ensures that the medium pressure gas in the hose increases at a faster rate than ambient, providing unmatched reliability and efficiency.
