This package includes two Halcyon H-75P piston first stages, an adjustable Halcyon Halo second stage as the primary regulator, an Aura second stage as the backup, and all the essential accessories you need for your dive.
Package Components
- Primary Second Stage: Halcyon Halo with a 7′ (210cm) rubber hose
- Backup Second Stage: Halcyon Aura with a 24″ rubber hose
- First Stages: Two Halcyon piston H-75P First Stages (DIN fitting)
- SPG: Halcyon 63mm 360 bar SPG with 24″ or 26″ rubber hose
- Backup Regulator Necklace
- Bolt Snaps: 3/8″ stainless steel for the main regulator, 1/2″ stainless steel for the SPG
Halcyon Halo and Aura Second Stages
Both the Halo and Aura second stages come equipped with the Air Control Vane (ACV), a feature designed to optimize breathing performance. The ACV system utilizes vacuum-assist technology to reduce the work of breathing, making each dive more comfortable and less strenuous.
- ACV in the “dive” position: Provides powerful breathing support.
- ACV in the “Halcyon” position: Prevents free flow, ideal for the surface, diving in currents, or while using the Aura as a backup regulator.
The Comfort Mouthpiece in both second stages helps reduce jaw fatigue and mouth irritation, ensuring comfort throughout your dive. This durable mouthpiece requires minimal effort to keep comfortably in place.
Key Features of the Halcyon DIR Twinset Regulator Package
- Breathing Comfort: ACV system in both second stages for reduced work of breathing and increased comfort.
- Durable Mouthpiece: The Comfort Mouthpiece minimizes jaw fatigue and mouth irritation.
- Long Hose Flexibility: The primary long hose allows for greater freedom of head movement during the dive.
- Backup Regulator Necklace: A convenient solution for securing the backup regulator.
Halcyon Halo – Main Regulator
The Halcyon Halo second stage is built for demanding divers, offering superior performance and reliability. With its dual adjustment system, the Halo provides precise breathing control for a wide range of dive conditions, making it the top choice for divers who demand the best in their gear.
Halcyon Halo – Primary Regulator
The Halcyon Halo second stage provides exceptional, smooth performance in all conditions, thanks to its innovative design and enhanced technology. This regulator delivers a high volume of air effortlessly, ensuring that breathing underwater feels completely natural. The Halo’s performance will captivate you the moment you experience its fluid, high-volume air delivery.
Key Features of the Halcyon Halo:
- Balanced, Adjustable Downstream Valve: The balanced downstream valve offers incredibly smooth breathing, reducing inhalation resistance by offsetting the force of air entering from the first stage. This results in a lower spring tension, making each breath feel effortless.
- Adjustable Inhalation Control: The inhalation control knob allows divers to fine-tune air delivery, making it easier to adjust breathing effort to suit varying dive conditions.
- Compatible with 40% Nitrox (outside the EU): Safe for use with Nitrox blends up to 40% (excluding the EU).
- Air Control Vane (ACV): The ACV system allows fine-tuning of breathing effort and helps prevent free flow under certain conditions.
Halcyon Aura – Backup Regulator
The Halcyon Aura second stage is designed for simplicity and reliability, delivering smooth, consistent airflow in a compact form. Its design and features make it an ideal choice for a backup regulator.
Key Features of the Halcyon Aura:
- Classic Downstream Valve: The downstream valve, a tried-and-true design, ensures reliable performance with a spring that counteracts the incoming airflow. This creates the perfect balance between ease of inhalation and consistent air delivery.
- Pre-Set Inhalation Effort: The Aura’s pre-set inhalation effort suits most diving conditions, providing dependable performance without needing frequent adjustments, making it perfect as a backup regulator.
- Air Control Vane (ACV): The ACV system, present in the Aura, helps regulate breathing and prevents free flow, especially useful in surface conditions, currents, or when used as a backup regulator.
- Compatible with 40% Nitrox (outside the EU): Safe for use with Nitrox blends up to 40% (excluding the EU).
- Non-Adjustable Downstream Valve: The non-adjustable design simplifies usage while maintaining reliability.
Halcyon H-75P First Stages
The Halcyon H-75P first stage is a state-of-the-art piston regulator that guarantees smooth and consistent air delivery throughout your dive. Featuring advanced technology, it is designed to provide precision breathing at nearly any tank pressure or water temperature.
Key Features of the Halcyon H-75P First Stages:
- Air-Balanced Flow-Through Piston: This design ensures optimal air delivery, remaining unaffected by changes in tank pressure. The balanced piston system provides a consistent and reliable flow of air, regardless of the depth or remaining air in the tank.
- Lightweight and Responsive Components: The first stage is built with responsive, lightweight materials that allow quick adjustments to breathing demands in all conditions, whether at extreme depths or during surface ascents.
- Remarkable Ease of Breathing: The H-75P provides smooth breathing whether you’re in the final stages of an extreme cave dive or making a relaxed ascent after a wall dive, such as in Grand Cayman.
This sophisticated technology ensures divers experience maximum comfort, making the Halcyon H-75P first stage one of the most reliable and efficient choices available in the industry.
Rotating Swivel
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.
- Balanced, freeze-resistant piston design
- Rotating swivel
- 2 x High-pressure Ports
- 5 x Low-pressure Ports (3/8)
- 300-bar DIN, compatible with 40% Nitrox
