A splash of decompression theory, a dash of common sense, bucketload of practice covered with dive planning, and you got the XR Nitrox course!
This programme qualifies you to dive to 40 metres using nitrox and to do 15 minutes of decompression. Your deco gas can be anything up to 50% nitrox, but you cannot do acceleration on the stage gas. You will learn to plan your decos, and execute that plan while maintaining buoyancy and trim to the required standard.
The programme can be completed wearing your standard total diving system, a large cylinder with H or Y valve, a full twinset, or in sidemount configuration.
The longer bottom times you get from limited decompression will allow you to wander around the wrecks and deep parts of pinnacles - and the course prepares you for the Technical Extended Range courses!
