We frequently get asked the question as to why we use O2 as a calibration source for oxygen sensors in closed circuit rebreathers (CCR). A CCR dive...

At Shearwater, we place a high value in the work being done by the scientific community relating to diving and decompression theory. We do our best...

For many years it has been common practice for rebreather divers to start breathing from their rebreather prior to the dive. There has been a recen...

We were very busy at Shearwater during the month of March. We managed to trot around the globe to 3 different trade shows: OZTek Dive Conference & Exhibition, Dive Resort Travel Shanghai, and Beneath the Sea.
