We offer the full line of XR courses: SSI Foundation, SSI Extended Range Nitrox,

SSI Extended Range/Extended Range Trimix

The SSI Extended Range program provides divers with the training necessary to independently plan and conduct limited decompression dives to a maximum depth of 45 meters, using decompression mixtures of up to 100% oxygen for a maximum accumulated decompression time of 25 minutes. The SSI Extended Range can be either done with a XR Sidemount or Twinset Total Diving System. There is even a Trimix option available for those who prefer to have a clear mind at 45m! In that case the Open Water Training dives 5 and 6 will be done using Trimix as a breathing gas..
