This year equipment has not seen any major evolution. 300 bars
tanks are becoming standard and rebreathers are growing in success.
Dräger comes first with its Atlantis/Dolphin and its newer Ray
(Nitrox semi closed circuit) and for Closed Circuit the Inspiration
from BUDDY (mixed gas closed circuit). Beware however that this
unit also holds the worst casualty record with its catastrophic
1%.
The Nitrox Stick (system designed to blend Nitrox into tanks
not oxygen cleaned using a standard compressor) still not as popular
as it should be.
