Have you heard the dreaded sound of the recall signal?

One of the downsides of advanced scuba certification is that you become aware, and sometimes its painful awareness, of how many people struggle with scuba diving.  You also tend to become more sensitive to watching and listening to other divers to find out if they are likely to have problems with the dive. Typically I am watching to see how divers put their gear together to see whether they know how it should be assembled and to see how confident they are in their topside skills. If they don’t know how their gear goes together, that is usually a pretty good sign someone on the dive needs to keep an eye on them underwater because chances are pretty good if something goes sideways they could easily panic and hurt themselves. Sometimes I hear divers say things that just don’t make any sense to me; like an average sized diver asking for about twice as much weight as I would expect he would need. I’m learning that when I hear things like that I really need to watch those divers.

One of the really bad sounds to hear when you are underwater is the captain of the boat pounding a weight on the hull of the boat as a recall signal. A repeated Bang bang bang sound usually means that something has gone very wrong for someone on the dive.

Not long ago I was diving in the Bahamas.  We had quite a few dive professionals on the boat; and we had one rookie blue water diver and an older diver among others. The rookie was buddied up with a dive master and the older diver was buddied up with another dive master. My buddy and I were near the other dive leader and were following him into the current to get to some swim throughs.  I noticed that the older diver seemed to have some problems with buoyancy, and he was way too involved in looking at his go pro. The rookie diver looked like he would huff through his air pretty fast. I figured he would be on the surface inside of 20 minutes on what otherwise would have been at least a 45 minute dive. Once I saw Harry, the older diver in the water, it was pretty obvious he would be all over the place, would have bouyancy problems and I figures he might be down 25 minutes.

At about the 20 minute mark my buddy and I had entered a swim through and were quite a ways into the swim through when I heard the dreaded bang bang bang of the recall signal. We came  out of the swim through and headed to the boat with the current at our backs. We were going relatively quickly, in part because the current was at our backs.  Not long after  I heard the recall signal, I shut down the camera and started kicking towards the boat. We rose in the water column and did most of our safety stop on the way back to the boat. When we got on board, the rookie was sitting on the floor of the boat, but otherwise appeared to be alright. I looked around for Harry and he was no where in sight. I hadn’t seen Harry on the way back to the boat so I assumed something was wrong. Actually, after I looked around the boat and realized Harry wasn’t there, the first thought that came to mind was “oh boy” Harry’s dead.

The captain looked a little nervous, but did not seem to be completely upset. I kept looking in the vicinity of the boat expecting to see other divers. Finally, when my gaze shifted out to about 200 meters away from the boat I could see someone holding on to another mooring line. As the boat made its way over to the other mooring line I could see Harry holding on to the mooring bouy and one of the dive staff was with him. Harry had blown thorough his air and had not been able to swim back to the boat because of the current. Fortunately, the dive leader assigned to him had helped him drop weights after he surfaced and had manually inflated his BC. Harry was ok, but needed help getting back on the boat. Had Harry not been with a professional, Harry could have gotten himself into some real trouble. Harry by his own admission was overweighted, underinflated and unable to do anything except hold on to the mooring bouy. And, until his weights were dropped by the diver professional, Harry was “drinking” a lot of sea water. Harry’s situation could have gotten really bad if he had not had immediate help.

The dive staff earned their pay that day. And just in case you are curious what it sounds like to hear a weight banging on the hull of a boat, here is the last bit of the dive with the banging at the end.

In reflection, the dives for 2015 for me, are pretty much done for the year. Everyone came back more or less in one piece. No one got bent. No one suffered a serious injury. So I do have a lot to be thankful for; I just wish the Harry’s of the diving world would be a little more careful, and maybe take a refresher course so they wouldn’t take such big risks.
