Shearwater Research is a Canadian manufacturer of dive computers and rebreather electronics for technical diving.

History

Petrel OC/CC Standalone

From the very beginning the company sought to develop products that are simple to use and easy to read underwater.[1][2]

In 2004, Shearwater Research was founded by Bruce Partridge who produced their products in a spare bedroom at his home.[1] As of 2014, Shearwater was producing thousands of dive computers per year in a manufacturing facility with twenty employees.[1]

Shearwater Research began by building controller boards for the Innerspace Systems Corp (ISC) Megalodon rebreathers in 2004.[3] There was a problem with the configuration and by the end of 2005, ISC was no longer offering the Shearwater electronics package.[3] Since that time, the initial issues have been resolved and Shearwater electronics are again available for use on the ISC Megalodons.[4]

Predator OC/CC External

Shearwater decompression computers began with an implementation of the Bühlmann decompression algorithm into their Shearwater GF in the Spring of 2006.[5] It was available in either the partial pressure of oxygen with decompression or control versions.[5][6] In January 2007, the Shearwater GF was the computer used with the JJ-CCR.[7]

With the release of the Predator in 2009, Shearwater moved away from the old LCD display technology to the use of new OLED displays in their computers.[8][9] This was the first color OLED diving computer available in the market with a user replaceable battery.[2] Power was a major limiting factor in the development process to include the OLED technology.[2]

Shearwater received their certification for ISO 9001-2008 in 2010 and all their products are complient with CE, FCC and IC international standards.[10]

With the Predator, Shearwater also introduced bluetooth to allow easier syncing with their desktop software.[2][8] Their reason for the move to bluetooth was to make a computer that could be used on multiple operating systems.[2] The Predator's two button design has been called "intuitive and easy to use".[11] The top of the line Predator will also allow for up to five breathing gases for the rebreather and up to five bail-out gasses.[9] The user can make gas switches on the computer at any point during the dive.[11]

In 2011, Shearwater announced that they had licensed a technique to monitor carbon dioxide absorbent canister developed by the United States Navy Experimental Diving Unit.[12][13][14] In collaboration with rEvo rebreathers, they were able to show that the thermal canister CO2 monitor would work with Shearwater's Predator dive computer.[15]

Shearwater has continued to develop new ways to calculate decompression in their equipment by releasing an implementation of the Varying Permeability Model (VPM-B/GFS) in 2011.[16] The "GFS" is for Gradient Factor Surfacing and indicates the combination were VPM and GF models are compared and the longer time utilized for the displayed profile.[16]

The Shearwater Petrel has been called the "Predator with improvements".[17] The Petrel was designed to allow a standard AA battery to drive the power it needs for calculations and OLED display with automatic brightness changing.[17][18] The unit is 40% smaller than the Predator.[18] The Petrel includes both the Bühlmann algorithm and their VPM-B/GFS algorithm.[17] The Petrel also extends the profile data storage that was previously available from 200 to approximately 1000 hours.[17]

With the release of the Petrel, Shearwater has also improved the educational materials available to their owners.[18]

In 2013, Shearwater was presented with the International System Safety Society Award for safety in "Scientific Research & Development" at the 31st International System Safety Conference in Boston.[19]

Shearwater's NERD or Near Eye Remote Display is a head-up display that places the divers information in front of their eyes.[20] The Shearwater NERD was released at Dive 2013 in Birmingham, UK.[20]

Safety outreach

In 2010, Shearwater was one of the founding manufacturers for the Rebreather Education and Safety Association.[21] Shearwater's Bruce Partridge served as Secretary for the founding board of the organization.[21]

Partridge also presented at the Rebreather Forum 3 meeting held in 2012.[22] He presented on the use of information technology with focus on human factors in equipment design.[23]

Shearwater is also a sponsor for the diving research efforts of the Rubicon Foundation.[24]

Exploration support

A Shearwater Predator was used to calculate decompression on a 2010 expedition that lead to the identification of the HMS Snaefell that went down on July 5, 1941.[25]

Lance Robb utilized an ISC Megalodon rebreather with a Shearwater Predator in a 2010 expedition to explore Osprey Reef at a depth of 156 m (512 ft).[26]

Shearwater also supported research by the University of Connecticut and Ocean Opportunity to explore the Tongue of the Ocean. This project, funded by the National Geographic Society/ Waitt Grants Program to explore the mesophotic zone between 200 ft (61 m) and 500 ft (150 m) carried The Explorers Club flag number 172.[27] The Shearwater electronics were utilized to record the diver profiles.[28][29]
