Technical Extended Range

Into the Black and Back to the Blue

When the deep calls, the technical diver answers. Go deeper and stay there longer!

The SSI Technical XR programme qualifies you to dive to 50 or 60 metres using nitrox mixes up to 100% oxygen, and to do unlimited decompression using two stage decompression gases. The programme can only be completed using specialized technical diving equipment. The training can be conducted using air or limited Trimix.

You will learn to plan and execute accelerated multi-gas decompression dives. This allows you to stay deeper for longer, explore more, and use the full technical diving equipment set.
