1. Why did it happen?
--Long Hose Reg: Afterward, found that adjustment knob on 2nd stage blew out causing unrecoverable catastrophic free-flow.
2. What depth?
--Doing an initial weight check at 6m/20'
3. What was your reaction?
--Ah! Simple free-flow . . .hey! I can't stop it!!!:shocked2:
4. What was your ascent rate?
-- around 15-20'/min (4-6m/min).
5. Did you have to go to the chamber?
--No, not for that incident
!
6. General experience/thoughts/advice/anything else relevant
--Single Tank Dive. Switched to bungie necklaced back-up reg, instead of trying to "sip" air from the malfunctioning regulator. Had a moment to unclip the SPG and actually see that pointer quickly sweep from 2000 down to 800psi . . .reached behind and shut down tank valve and started CESA. Feathered/modulated tank valve on ascent to take breaths. Had enough gas for a 30sec safety stop at 3m/10'. Surfaced with barely enough tank pressure to inflate my wing (and one hand already undoing/about to ditch my weightbelt). . .
Feathering your tank valve is a skill that's not always taught in mainstream BOW classes; it's a vital technique to learn and practice, especially if your dive buddy is nowhere to be seen, or if you're diving solo. . .
