The SAILOR SE-II and SGE-II Satellite EPIRBs are satellite distress beacons designed to operate in conjunction with the Cospas-Sarsat international satellite search and rescue system.
The SE-II and the SGE-II is identical except for the GPS built into the the SGE-II, which improves the accurasy of the position transmitted to shore when activated. The EPIRBs are supplied with either a manual release bracket or with an automatic hydrostatic release bracket, which will automatically release the EPIRB in situation where the vessel is sinking.
