The SSI Technical Extended Range program provides divers with the training necessary to independently plan and conduct two-gas switch, multiple-stop decompression dives to depths of up to 50m (60m when using trimix), using specialised diving equipment and procedures with an equally-qualified dive buddy.

Two stage cylinders and stage regulators, oxygen cleaned as required or,
A complete XR Sidemount Total Diving System appropriate for multiple-gas switch, accelerated decompression diving. Two stage cylinders and stage regulators, oxygen cleaned as required.
We will complete a days academic development classroom session.

How it works
You will be given sent an email to view the course materials on www.divessi.com to start your academic development. We will schedule 1 day to complete the first part of the academic development and kit configuration session. The Pool session will contain the swim test and skill development. 3 days of Open Water will be the bulk of the program, with thorough de-briefing and feedback given at the end of each day.
