Scuba Schools International (SSI) has a wide range of Open Circuit technical diving courses designed to meet the needs of new and experienced technical divers. SSI&rsquo;s suite of Extended Range dive courses run from a basic foundations course right through to hypoxic trimix and diving to 100 metres with unlimited decompression. Course requirements include the planning of dives to a specific depth and for a specific bottom time. As part of this planning you will be required to plan the optimal gas mixes required, run times and decompression commitments. You will also learn important in-water skills including gas switching, buoyancy control, use of an SMB and rescue procedures.
The SSI Technical Dive package also includes specialist courses for those divers interested in diving in overhead environments. These courses include advanced and technical wreck diving as well as cavern diving. There is also an extended range gas blender course for those divers who wish to know more about the gas mixes they are diving with. &nbsp;For information on the particular course that you are interested in click on the relevant SSI badge below
