ACR Part # 9490 (was 9402)

  • When submerged in water between 5-13 ft. (1.5 - 4 m), the HydroFix will disengage the rod allowing the Category 1 bracket to release the EBIRB.
  • ACR has designed a patent pending release rod system, which does not depend on a battery, sharp blade, or a pyrotechnic device to release the beacon.
  • Designed to work with ACR's Open Face, Sea Shelter and Sea Shelter2 brackets.
  • This advantage allows ACR to offer an HRU that is individually tested to ensure that the HydroFix is the most reliable HRU in an emergency situation.
  • All HydroFix units are tested to the same high standards and quality workmanship you have come to expect from ACR over the past 50 years.
