McMurdo breaktHRU

The McMurdo HRU (Hydrostatic Release Unit) is the water pressure activated automatic release mechanism for the Smartfind Plus EPIRB Auto Housing (E5 / G5) and older McMurdo EPIRB models (E3 / G4, Rescue406 / Precision406).

The HRU is designed to automatically release the Auto Housing cover and discharge the Smartfind Plus EPIRB at a depth of between 2 – 4 metres. This action is carried out by a small charge within the HRU forcing a blade to cut through a plastic retaining bolt, releasing both the Auto Housing cover and a spring that forces a lever arm to eject the Smartfind Plus EPIRB.
