The SSI EXTENDED RANGE (XR) line of courses is designed to adequately prepare divers to push their limits - both in terms of dive time and depths reached. Proper training and preparation allows you to safely exceed 40 meters in depth and extend the dive time also by properly planned decompression stops. We invite you to the first course of the SSI EXTENDED RANGE path - EXTENDED RANGE FOUNDATIONS On this course, the main emphasis is on learning the new configuration (dives take place with a two-bottle set), procedures specific to technical diving, and learning and improving skills from previous courses - swimming techniques, trim and neutral buoyancy. The training is an introduction to technical diving and subsequent XR courses. But not only... it is an excellent training for any diver - regardless of whether he plans to dive technically or not, whether he plans to change from a single cylinder to a twine, side mount kit or closed circuit. At the training we improve our own diving skills, the acquired knowledge and skills will allow us to dive more safely and comfortably - the improved technique will allow us to move more efficiently underwater and reduce air consumption.
