The Calypso 2nd stage utilizes an oversized, easy-to-reach purge button for quick and efficient purging of water from the mouthpiece. It is equipped with an adjustable inhalation effort knob that enables easy fine-tuning of breath resistance to suit individual diver preferences. The Calypso 2nd stage regulator also features a dual-density plastic mouthpiece that offers optimal comfort and excellent grip.
The regulator comes with a 3000 lb. (1361 kg) hose length of 49.5 ft (15.1 m) to provide ample hose length for divers, enhancing versatility and flexibility during underwater explorations. The yoke connection on the first stage makes it compatible with QC1, QC2, and DC2 SCUBAPRO or EP high-pressure inflators.
In summary, The Scubapro Aqua Lung Oceanic Mares Cressi Dacor HD0528 Calypso 2nd Stage Regulator with a 3000 lp hose and a 49.5 ft yoke offers a superior diving experience with its advanced, pneumatically-balanced design, exceptional performance in various conditions, and user-friendly features.
