ACR 9490-1 HydroFix Hydrostatic Release Unit for Category I EPIRBs

Patented rod system allows release of the beacon from a Category I bracket when submerged in water between 1.5 - 4 meters (4.9 - 13.1 feet).  Designed to work with Sea Shelter™, Sea Shelter™2 and Sea Shelter™3 brackets

A patented rod system does not rely on a battery, blade or pyrotechnic device to release the beacon. This advantage allows for a quick, seamless and reliable release in an emergency.

Note that this is a date-stamped product and must be replaced every 2 years from the date of installation or 4 years from the date of manufacture.
