The Nitrox Plus Diver course builds upon enriched air diving knowledge and introduces divers to using twin cylinders for greater gas supply and safety. Aimed at recreational divers ready to progress towards technical diving, it focuses on managing two-cylinder setups, extended dive planning, and deeper dives up to 40 metres.
Training starts at the Gosforth dive centre, where instructors introduce advanced Nitrox theory and dual-cylinder handling. You’ll review gas physiology, dive limits, and planning procedures for deeper dives, gaining an understanding of how to balance oxygen exposure with gas reserves. The classroom element also covers equipment configuration, including regulator setup and safety checks for using two cylinders.
Confined water sessions allow you to become familiar with the twin-cylinder system and buoyancy control before heading to open water. During the open water dives, you’ll practise switching gases, monitoring exposure, and maintaining buoyancy at depth. The course focuses on control, precision, and awareness, helping divers gain the confidence to handle extended dive times and deeper environments safely.
Classroom training takes place at the Gosforth dive centre (NE3 2HY). Confined water sessions are held at Elsdon Avenue Pool in Seaton Delaval, Whitley Bay (NE25 0BP), providing a calm environment for equipment setup and control practice. Open water dives are completed at suitable UK dive sites such as Capernwray Quarry, Ellerton Lake, or Beadnell Bay, chosen for their safe access and visibility.
Each site provides the right conditions for real-world practice, ensuring you can apply your new skills effectively. The combination of theory, confined, and open water elements delivers a well-rounded and practical learning experience.
Divers must hold an Open Water Diver and standard Nitrox certification or equivalent. You should have a solid understanding of buoyancy and underwater control, with prior experience in standard single-cylinder diving.
This course bridges recreational and technical diving, providing a smooth transition to more advanced levels. Instructors guide each participant carefully to ensure comfort and competence before moving on to deeper dives and dual-cylinder setups.
Instruction is led by experienced divers who focus on practical skills, safety, and confidence-building. Each session is designed to be clear and supportive, helping divers make the transition towards more complex gas management systems.
Small group sizes ensure personalised supervision during both theory and in-water training. The combination of professional teaching, flexible scheduling, and diverse dive locations creates an ideal environment for advanced learning.
