Scubasailor, this was a wonderful experience! You didn't get hurt, and there were a whole bunch of lessons that got highlighted here, and nothing causes a deeper impression than a personal experience.
In my experience, buddy checks are one of the first things to go after people get certified. We've even had DMs on resort boats HASSLE us for doing them, because they wanted us into the water faster. But solving problems on the surface is ALWAYS easier than solving them underwater, so anything you can catch on land is worth doing there.
In addition, you learned another important lesson . . . Descents are one of the times when things go wrong, or when you become aware of things going wrong, so descents are one of the critical times to keep the team TOGETHER. All too often, I see people jump off the boat and descend without reference to one another, with the intention of regrouping at the bottom of the anchor or wherever. But if one person has a gear issue, or can't equalize, or finds out his valve isn't completely open, that's the time to have ones buddy nearby to help.
Anyway, congratulations on calmly handling the issue. You won't forget this quickly!
