The SSI Technical Extended Range course is designed for divers ready to advance into deeper, more demanding environments using either open circuit or closed circuit systems. In this program you will learn to manage twin tanks, carry and deploy two pony bottles, and work with advanced gas mixtures, including limited trimix, under the guidance of an experienced technical instructor. Training focuses on precision buoyancy, advanced propulsion, equipment configuration, gas planning, and safe procedures for extended depth diving. This course is ideal for divers who want to push their limits responsibly, strengthen their technical foundation, and prepare for deeper future training while maintaining strong safety protocols.
