Shearwater Dive Computers

Shearwater Research designs and manufactures dive computers for the most demanding technical divers.

Shearwater Petrel and Predator Trimix Computers | Shearwater Predator Trimix Dive Computer | http://www.shearwaterresearch.comThe owner of Shearwater Research, Bruce Partridge, has designed and implemented computer systems since 1972. In a career that spans decades, Bruce has worked in design, operations, and programming in computers and data communications. In 2005, with the experience gained from the previous years of development, Bruce decided to redesign from the ground up using the latest techniques and components. The process control industry provided a wealth of knowledge on controllers, alarms and many other design decisions. This solid foundation was paired with an overriding desire to produce electronics that hide the complexity behind simple, easy to understand, interfaces.

Scuba Center is an authorized Shearwater Dealer.
This is your assurance that your equipment will come with the full manufacturer's warranty.

Shearwater Petrel: Everything you've come to expect and more!
Shearwater Petrel EXT | Available online and at Scuba Center in Eagan, MinnesotaThe Shearwater Petrel incorporates all features of the Predator, plus includes new hardware and software features. 40% smaller than Predator, it includes OC/CC and a flexible choice of batteries.

Firmware was branched from the Predator V45 firmware, and will be very familiar to users of the Predator.

The Petrel display is an LCD with LED backlight as opposed to the OLED display in the Predator. Size and resolution are the same. Shearwater found the display to be as readable as the Predator’s, and better in some conditions such as bright sunlight.
