Extended Range

The SSI Extended Range Trimix training program is the foundation on which all other open circuit programs are built. This program marks the start of an exciting journey towards becoming a fully-fledged technical diver. Whether in sidemount or twin-bottle configuration, this program prepares you to plan and execute trimix decompression dives to a maximum depth of 45 m. You'll learn the techniques and procedures for using trimix and nitrox breathing mixes (up to 100% oxygen) for decompression. At the end of the program, you'll be certified as an SSI Extended Range Trimix diver, and your knowledge of technical diving will be further enhanced.
