McMurdo Replacement HRU Kit for G8 EPIRB

The McMurdo Replacement HRU Kit is a hydrostatic release unit for McMurdo G8 series EPIRBs.

Hydrostatic release units are consumables with a fixed service life, typically two years, and replacing one is scheduled maintenance rather than a repair. The date is marked on the unit, and a beacon with an expired HRU fails inspection even though the beacon itself is fully serviceable.

This kit suits the G8 series specifically, so the beacon model should be confirmed rather than assumed from the brand. The HRU is what lets a Category 1 EPIRB float free and activate on its own as a vessel sinks, which is the entire reason for fitting one rather than a manual beacon.
