This weekend I was on a fun dive in Monterey with my LDS and the SPG blew off the HP hose underwater. I'm wondering if anyone has experienced this before or may have an idea of the cause?
Details:
It was a shore dive at McAbee beach and occurred 18 minutes into the dive at 28ft depth. I reached down with my left hand to look at my SPG and as I pulled up, it shot out of my hand, along with the spool. Fortunately I still had about 2,000 psi in the tank so was able to ascend and swim back to shore safely with my buddies. I wasn't able to recover the spg and only have the hose left to examine. My LDS inspected it and didn't note any scarring in the hose threads. Their assumption is that it wasn't properly torqued down and may have loosened over time.
It was a HOG 2" SPG attached to a 24" braided hose that I purchased from Piranha Dive Mfg a couple months ago. This was my second dive with it, so fairly new. Randy claims it's impossible for this to have occurred as the SPG was under pressure, but I have several witnesses that would disagree. My thought is perhaps the bolt snap location was partially to blame but am interested to hear other opinions. I have two more of these SPGs for my son and wife and want to ensure that they don't experience the same issue. Attached is a photo of the hose threads and an example of how I had the boltsnap connected. Appreciate any feedback.
Only other details I can think of that may be relevant is that the spg was connected to a D ring above my left hip and was still connected as I pulled up. I typically don't need to unclip the boltsnap to read the gauge. There were also no bubbles that I noticed which I would expect if the spg was partially unthreaded. I had also checked my gauge one time already during this dive.
Thanks!
