Hi all, I thought I should 'fess up that I'm really annoyed with myself. Yesterday, I was on my first sea dive of the year having had a couple of blow-outs in recent weeks. The weather gods were with us, and we found ourselves on a relatively calm channel, in good visibility allowing us to dive the Holland 5 submarine wreck in about 32 of water - a dive I have done before in considerably worse conditions and really enjoyed! Anyway - the dive started and my buddy and I were the first into the water and down the shot (after the skipper who had gone to "set the hook" to use a horrible Americanism). All started off well, but I had a bit of difficulty equalising, pausing on my descent just long enough for the line and buddy to get a bit further away from me. I finned after them and caught up, at the back of the wreck at 30m after a fairly quick descent - but my breathing was rapid after a quick fin. (I'm a fairly fit 34 year old - so this was a bit odd). I tried to get my head in gear and relax my breathing - went to do a reg exchange / test and sent up a flood of bubbles (I'm not really sure why). Anyway - I basically had a "funny moment" and struggled to relax. I signalled to my buddy that I wasn't really okay and we thumbed the dive - back on the boat after 10 minutes in otherwise great conditions. I'm trying to analyse "what went wrong" - and the weird thing is, nothing really did! I felt bad for my buddy for messing what could have been a great dive on a lovely wreck in good conditions - on the other hand, I am glad that I didn't try and force myself to continue and then get myself into trouble. We went on to have a great second dive on the Norman's bay cannon wreck which somewhat made up for it, but I now wonder, other than the "stop and relax" bit, what I should have / could have done. Has anyone else had a dive that just didn't feel right, but they're not sure why? I've never thumbed a dive like that before... Maybe I'm going barmy!
