Classic Apeks DS4 Twinset Regulator Package

The Classic Apeks DS4 Twinset Regulator Package includes two environmentally sealed first stages. This package also contains an adjustable main second stage and a non-adjustable backup. Long and backup regulator hoses complete this reliable twinset configuration.

DS4 Twinset Regulator Package Includes:

• 2 x Apeks DS4 DIN first stages
• Apeks XTX50 second stage (main)
• Apeks XTX40 second stage (backup)
• 210cm (7') main rubber regulator hose
• 24" backup rubber regulator hose

XTX50 Second Stage

The classic and popular Apeks XTX50 Second Stage allows precise control of breathing effort with its breathing effort adjustment. Furthermore, the XTX50’s second stage can be converted from a right-handed to a left-handed hose configuration. This feature is known as the Reversible Venturi System (RVS). Any Apeks Authorised Service Technician can perform this quick and simple change.

Moreover, the XTX50 Second Stage incorporates the Diver Changeable Exhausts (DCE) system. This system enables divers to switch between a small and a large exhaust tee. For example, the wider exhaust tee minimizes bubble interference, ideal for underwater photography. Conversely, the narrow exhaust tee offers a smaller, more compact, and comfortable setup.

Additionally, the Apeks XTX50 second stage features a two-shot high-strength composite front cover. This significantly improves the durability of the demand valve's most vulnerable part. The ergonomic Venturi lever has been designed to reduce the amount of grit ingress. Finally, a silicone exhaust valve enhances the XTX50 Second Stage's breathing performance.

• Adjustable breathing adjustment control
• Integrated venturi control
• Pneumatically balanced valve design
• Micro Adjuster
• Suitable for cold water use
• Right or Left hand hose configuration
• Changeable Exhaust Tees (not included)

XTX40 Second Stage

The Apeks XTX40 Second Stage is a highly recommended primary or backup regulator. It features a pneumatically balanced second stage and venturi control for smooth inhalation. Similarly to the XTX50, the XTX40’s second stage can be converted from a right-handed to a left-handed hose configuration using the Reversible Venturi System (RVS). This conversion is quick and simple for any Apeks Authorised Service Technician.

Furthermore, the XTX40 Second Stage includes the Diver Changeable Exhausts (DCE) system. This allows divers to choose between a small and a large exhaust tee. Consequently, divers can optimise for minimal bubble interference during underwater photography or a more compact profile.

• Integrated venturi control
• Pneumatically balanced valve design
• Suitable for cold and warm water use
• Right or Left-hand hose configuration
• Changeable Exhaust Tees (not included)

Apeks DS4 First Stage

The Apeks DS4 First Stage is a reliable workhorse with years of proven performance favoured by demanding technical divers. For a long time, these have been popular first stages for twinset configurations. The Apeks DS4 is over-balanced, providing maximum performance at greater depths.

Additionally, a dry chamber prevents water from contacting the first stage spring. This crucial feature stops freezing in cold water environments. The Apeks DS4 First Stage is environmentally dry-sealed for increased reliability. It features four medium-pressure (MP) ports and one high-pressure (HP) port. Finally, it is finished in highly polished chrome for durability and a sleek appearance.

• Environmentally dry sealed
• Four MP ports
• One HP port
• Adjustable intermediate pressure
• Finished in highly polished chrome
