For the EPIRB, what depth of water will the HRU release at?

A hydrostatic release unit works by water pressure to automatically detach the EPIRB from its raft when it’s submerged to a certain depth, ensuring the beacon can float free and transmit for rescue. The recommended depth is about three to ten feet of water. This range is chosen to avoid accidental releases from splashes or rough seas (which would happen if it were set shallower) while still triggering reliably as the raft submerges enough to require the beacon to separate and float to the surface. Depths outside this range either risk premature release or inadequate release during submersion, so the three-to-ten-feet window is the practical, safe setting.
