Shearwater Research describes itself as “the world leader in the field of dive computers for serious scuba divers”. The company was founded in Canada in 2004 by Bruce Partridge, an advanced technical diver with a background in computer systems design and embedded programming. His vision for Shearwater was to provide reliable, user-friendly, easy-to-read computers to the diving community.

We all dive with Shearwater computers and couldn't rate them highly enough.
