Technology for Demanding Technical Divers


From its beginnings in 2004 Shearwater Research Inc. has been fueled by the passion and vision of its CEO Bruce Partridge. With a background in computer systems design, embedded programming and advanced technical diving, Bruce brings a unique perspective to the world of dive computers.

Core Values

Armed with the belief that divers want a simple intuitive user interface previously unavailable in dive computers and rebreather control systems, the earliest focus was on the design of a menu structure that made sense to the user. As an experienced rebreather and open circuit technical diver, Bruce clearly understood the need for divers to be offered reasonable choices, requiring as few button pushes as possible, during stressful underwater situations. Coupled with Bruce’s strong programming skills and demand for robust, reliable products, Shearwater Research has quickly become a major supplier of trimix computers and electronic control systems for rebreathers.


Shearwater places great value in the work being done by the scientific community relating to diving and decompression theory. It is common to find Shearwater representatives attending scientific symposiums and conferences around the world. We support evidence based decision making and the organizations that provide that evidence.

Commitment to Quality

All Shearwater products are designed and manufactured in Vancouver, Canada, in their certified ISO 9001-2008 compliant facility. Their products meet international standards as required by CE, FCC and IC.


Shearwater Research designs and manufactures open-circuit and closed-circuit trimix dive computers for the most demanding technical divers. We provide Buhlmann with Gradient Factors and VPM-B, the most common decompression models used by technical divers. A focus on innovative and simple displays keeps the most important information available at a glance.

Dive Action is the sole agent for Shearwater Research in South Africa.
