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. 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. ACR's HydroFix™ is now part of the standard replacement kit for the following EPIRBs* and brackets: Satellite 406™ (Closed and Open Face Brackets) Model: RLB-27 P/N 2754/2756/ 2772 Satellite2 406™ Model: RLB-32 P/N 2774 RapidFix™ 406 Model: RLB-33 P/N 2776 GlobalFix™ 406 Model: RLB-35 P/N 2742 Sea Shelter™ P/N 9327 Sea Shelter™2 *Not for use with RLB-23 406 EPIRB (fully enclosed bracket) P/N 9435/9455
