The Halcyon H-75P First Stage offers many refined features that ensure consistent delivery with performance that ranks among the very best in the diving industry.
The stable, intermediate pressure provides precise air delivery to the second stage. This means you will experience a remarkable ease of breathing while diving in all environments; this is true at nearly any tank pressure and within almost any water temperature. This sophisticated technology is among the best in the industry, freeing you to get the most out of your diving.
Air-balanced flow-through piston delivers an optimal amount of air to the second stage, remaining unaffected by changes in tank pressure. Lightweight & responsive components create prompt adjustments to breathing demands in all conditions, temperatures or tank pressures.
Enjoy the smoothest breathing regulator, whether on the final hours of an extreme cave exploration or on a blue water ascent after a magnificent Grand Cayman wall dive.
Rotating swivel provides flexibility and super clean hose routing. The Halcyon 360-degree swivel turret cap with high flow port ensures the best air delivery possible with up to 15% more air than other LP ports.
Combined with Halcyon’s “long” primary hose and backup necklace, your hoses can be configured where you need them.
Whether diving a sophisticated rebreather or a simple, open water system, you can create a configuration that supports easy movement, reduces jaw fatigue from ill-routed hose position and streamlines your diving profile.
Five High-flow Low-pressure Ports allow you to customise your hose routing for comfort and convenience.
Two opposing high-pressure ports allow you to choose where to route your SPG and allow the use of accessories. Most Halcyon divers route their pressure gauge to the left, but the Halcyon H-75P allows flexibility with any configuration you choose; these options provide freedom to support personalised and advanced hose routing configurations.
