Twinset Foundations / Intro-To-Doubles in Subic Bay

About the RAID Twinset Foundations Course

The RAID Twinset Foundations (Into-To-Doubles) course in Subic Bay is a pre-technical dive certification designed with the recreational diver in mind. The course provides students with the knowledge, and skill proficiency to safely utilize manifold doubles and backplate/wing BCDs with best practice protocols. This exclusive training is held in Subic Bay, Philippines.

Why learn to use doubles/twinset?

Learning to use doubles/twinset configuration gear offers several benefits for scuba divers, including:

• Extended dive time: Doubles/twinsets allow divers to carry more breathing gas, enabling longer dives where gas consumption is a limiting factor.
• Redundancy and safety: With separate cylinders and an isolation valve, divers have a backup gas supply in case of equipment failure, enhancing safety during deep and overhead environment dives.
• Improved balance and streamlined profile: Distributing weight on the back enhances horizontal trim, reducing drag and improving maneuverability.
• Flexibility and adaptability: Doubles/twinsets enable divers to mitigate foreseeable risks on more advanced and challenging dives in a range of diving environments and at deeper depths.
• Preparation for technical training: Learning to use doubles/twinset as a recreational diver allows an early start in developing equipment and protocol familiarity. If you subsequently enroll in a technical diving course, this can pay dividends in reducing task loading.

Proper training is crucial when using doubles/twinsets!

Using doubles/twinset for scuba diving without effective best-practice training can be dangerous due to:

• Incorrect equipment setup: Divers may lack knowledge of how to assemble and configure the gear correctly, leading to gas management and equipment failure issues.
• Lack of familiarity: Diving with doubles/twinset requires adjusting to different gear handling, which without training can lead to confusion and poor decision-making.
• Difficulty in valve shutdowns: Divers may struggle to shut off valves, especially in emergencies, potentially leading to gas loss.
• Increased risk during emergencies: Divers without training may struggle to handle equipment malfunctions and gas sharing effectively, compromising safety.
