The Mares Horizon SCR Diving Course certifies you to safely plan and conduct semi-closed rebreather dives up to 30 meters.
Across 3 to 4 days, you’ll master gas management, emergency procedures, pre-dive checks, and buoyancy control specific to the Horizon system.

Training includes classroom theory, confined water sessions, and multiple open water dives guided by our SSI XR Instructor Trainer.
You’ll experience unparalleled stability, extended dive time, and the freedom of silent exploration.

This program is perfect for experienced open-circuit divers ready to move into advanced, next-generation equipment — without the complexity of fully closed rebreathers.
