History Shearwater_Research

petrel oc/cc standalone

from beginning company sought develop products simple use , easy read underwater.

in 2004, shearwater research founded bruce partridge produced products in spare bedroom @ home. of 2014, shearwater producing thousands of dive computers per year in manufacturing facility twenty employees.

shearwater research began building controller boards innerspace systems corp (isc) megalodon rebreathers in 2004. there problem configuration , end of 2005, isc no longer offering shearwater electronics package. since time, initial issues have been resolved , shearwater electronics again available use on isc megalodons.

predator oc/cc external

shearwater decompression computers began implementation of bühlmann decompression algorithm shearwater gf in spring of 2006. available in either partial pressure of oxygen decompression or control versions. in january 2007, shearwater gf computer used jj-ccr.

with release of predator in 2009, shearwater moved away old lcd display technology use of new oled displays in computers. first color oled diving computer available in market user replaceable battery. power major limiting factor in development process include oled technology.

shearwater received certification iso 9001-2008 in 2010 , products complient ce, fcc , ic international standards.

with predator, shearwater introduced bluetooth allow easier syncing desktop software. reason move bluetooth make computer used on multiple operating systems. predator s 2 button design has been called intuitive , easy use . top of line predator allow 5 breathing gases rebreather , 5 bail-out gasses. user can make gas switches on computer @ point during dive.

in 2011, shearwater announced had licensed technique monitor carbon dioxide absorbent canister developed united states navy experimental diving unit. in collaboration revo rebreathers, able show thermal canister co2 monitor work shearwater s predator dive computer.

shearwater has continued develop new ways calculate decompression in equipment releasing implementation of varying permeability model (vpm-b/gfs) in 2011. gfs gradient factor surfacing , indicates combination vpm , gf models compared , longer time utilized displayed profile.

the shearwater petrel has been called predator improvements . petrel designed allow standard aa battery drive power needs calculations , oled display automatic brightness changing. unit 40% smaller predator. petrel includes both bühlmann algorithm , vpm-b/gfs algorithm. petrel extends profile data storage available 200 approximately 1000 hours.

with release of petrel, shearwater has improved educational materials available owners.

in 2013, shearwater presented international system safety society award safety in scientific research & development @ 31st international system safety conference in boston.

shearwater s nerd or near eye remote display head-up display places divers information in front of eyes. shearwater nerd released @ dive 2013 in birmingham, uk.

the recent computer, perdix, similar petrel has 30% longer battery life , thinner , lower profile. computer named after grey partridge .  (the founder s surname partridge)
