Thanks for the input everyone. The reg set has not been sent for inspection yet (I plan to do that on at year #2, coming up in January).
From what I gather, the hose doesn't raise anyone's immediate concern, so I'll find at my convenience someone to look at it in-person.
I will add one more vote, based on the photo, that the hose is probably "ok". I have a few that look like that.
However, to play Devil's Advocate, I should tell that I've had only one hose failure in almost 40 years of diving.
That hose actually looked better than the one in your picture; in fact it looked completely "normal" to me (but was an older hose; probably 15 years old). It failed dramatically, at the crimp, actually just slightly inside the crimp.
In my case it was a HP hose that failed, and failed on the surface when I first turned on the air... my feeling is this is the most likely time for a hose to fail, when it is first subjected to a sudden increase in pressure as you turn on the air...
but the possibility
does exist that it could fail underwater as well. The failure may begin as a slight leak, but hoses can just rupture without warning at/near the crimp as my hose did.
Again, I think your hose looks "ok", but keep this in mind.
As others have said, I would need to actually have the hose in front of me and examine it carefully before I'd be confident in saying it was "ok" (although I do believe yours is ok).
If you are
not confident in your ability to make the determination on your own, then do have someone look at the hose for you before you dive again.
Best wishes.
