Halcyon H-50D First Stage: High-Performance Design for Extreme Conditions
The Halcyon H-50D First Stage is engineered for high-performance and durability, designed to excel in harsh environments such as ice-cold waters or areas with environmental contaminants. With its diaphragm design, the H-50D is especially favored by cold-water divers and is built to meet the demands of the most extreme diving conditions.
Environmentally Sealed for Enhanced Performance
The H-50D features a balanced, environmentally sealed diaphragm first stage, ensuring top-tier performance even in cold water. Its dry, balanced chamber diaphragm design prevents water from entering the first stage mechanism, providing consistent and smooth breathing throughout your dive, regardless of tank pressures and depths.
This environmentally sealed design is ideal for divers who need reliable performance in cold and contaminated conditions, offering trouble-free operation in the harshest environments.
Versatile First Stage Ports for Customizable Hose Routing
The H-50D is equipped with two high-pressure ports, positioned oppositely, which give you flexibility when routing your SPG (submersible pressure gauge) and other accessories. While many divers route their pressure gauge to the left, the H-50D allows for any configuration that suits your preferences.
Additionally, the four low-pressure ports offer even more customization for hose routing, ensuring comfort and convenience. These low-pressure ports are high-flow, delivering up to 15% more air compared to standard LP ports, maximizing airflow for efficient performance.
Halcyon H-50D First Stage Features:
- Balanced, Sealed Diaphragm: Provides reliable performance in cold and contaminated environments.
- Dry Balance Chamber: Prevents water from entering the first stage mechanism, enhancing durability.
- 2 x High-Pressure Ports: Allows for flexible accessory configuration.
- 4 x Low-Pressure Ports (3/8): Customizable hose routing with high-flow options for better air delivery.
- 300-bar DIN: Compatible with 40% Nitrox for versatile use.
For divers looking for even more flexibility, consider the Halcyon H-75P first stage, featuring a 360-degree swivel turret for maximum freedom in hose routing.
