SCR XR Technical

Porto Santo Sub runs the SSI SCR Diving programme on the Mares Horizon Semi-Closed Rebreather, certifying divers to plan and conduct no-decompression dives to 30 m with the SCR unit. The Mares Horizon is the platform used throughout the programme — from confined water sessions through to the 4 open water dives required for certification.

Prerequisites are meaningful: 24 logged dives, an Enriched Air Nitrox specialty, and a Deep Diving specialty. The programme runs over 7 theoretical/configuration sessions, 2 confined water sessions and 4 open water dives, estimated at 24–30 hours total. José Ricardo and the team have been operating in Porto Santo's Atlantic waters long enough to know where conditions are stable enough for rebreather training dives.

The Mares Horizon SCR unit is available for rent as part of training at €150 for the course period. Nitrox fills and other consumables are charged separately. Minimum age is 18.
