Pushing the limits of recreational diving requires both skill and confidence. This course prepares you for dives up to 40 metres, with practical experience across diverse open water environments. You’ll learn advanced safety, planning, and navigation techniques while gaining hands-on deep diving practice.
Sessions are fully focused on open water diving, with four progressive dives to introduce and consolidate skills at depths up to 40 metres. Each dive builds confidence, safety awareness, and technique under instructor supervision.
During the dives, you will practise navigation, gas management, buoyancy control, and emergency drills. Instructors provide immediate feedback to refine skills and build comfort at depth.
The final dives integrate all previous skills, allowing you to confidently plan and execute dives to 40 metres while safely managing yourself and a buddy.
Capernwray quarry is ideal for deep dive training, featuring submerged attractions and controlled depths up to 22 metres. Ellerton inland lake offers silty-bottom challenges and shallow sections to practise specific skills. Beadnell Bay provides a natural shore dive environment with open water conditions that test adaptability.
Diving across multiple locations ensures you develop the versatility to handle different water conditions, visibility levels, and underwater features, enhancing both safety and experience.
Certified divers with prior open water experience are required. Recommended previous courses include Open Water 20 or Explorer 30 to ensure readiness for deeper dives.
Competence in dive planning, gas management, and emergency procedures is necessary. This course focuses on advanced depth techniques and realistic open water scenarios.
Expert instructors provide personalised guidance at every stage, combining feedback with practical exercises to enhance confidence and skill mastery. Real open water environments ensure your training translates directly to real-world diving.
Multiple dive sites and progressive exercises give you practical experience in varied conditions, preparing you for advanced recreational dives or professional progression.
