How we calculate scores →About this gear
The HydroFix is a hydrostatic release unit for compatible ACR SeaShelter, SeaShelter 2 and SeaShelter 3 EPIRB brackets. Its mechanical release rod operates without a battery, blade or pyrotechnic charge.
Consider before buying
It is a dated replacement component, not an EPIRB or a universal release. ACR specifies replacement after two years installed or four years from manufacture. A visually tidy unit can still be due for replacement.
Our take
Buy it by bracket compatibility and expiry date. A different brand’s release is not automatically interchangeable; the right alternative is whichever replacement the bracket manufacturer explicitly specifies.
