I know this is old thread but just thought I'd share this video. I was in Little Cayman in 2018 and on a dive with a boatload of strangers. Early in the dive I noticed this one diver that had some very serious "leakage" in her HP hose at about 60ft.... I felt that it was about to blow so took it upon myself to approach her, show her the issue and ascend with her to the surface.... It was a rental reg set so I went with her to the shop with her after we got back and showed them my video and suggested that they needed to check ALL of their rental gear.
She bought me drinks at the Beach Nuts Bar that night!
