i actually have a very simple story to share along the lines of what I was talking about.
I was diving w/ jorge off of elliot key and there was a HAULING current. we were only in about 10 -15 FSW and i found a nice little hole up under a fan coral. I checked it out and it was about a 3 ft deep and around hole that was holding at least 10 bugs. I dropped on it the first time and stuck my head in to see if i saw any bugs that were much bigger than the others. I ran out of bottom time and sufaced. As i was breathing on the surface the current pulled me about 25 ft off the spot i saw the hole, so when i dove again i had to fight the current to get back to the spot (this was the first mistake, i should have fought the current from the surface and then dropped). By the time i made it back to the hole and got my head inside and grabbed a bug I had very little air and i had been upsidedown in the hole for at least 35 seconds so i was disoriented. I felt the burn so i grabbed the two bugs i had gotten out of the hole and turned to the side i thought was up. i was a little turned around and i was actually close to horizontal when i tried to fin up. the disorientation coupled with the lack of air, compunded by the inital sprint of fighting the current all added up to a big second of pure panic. I almost immediately figured out which way was up and i was on the surface a tenth of a second after that, but that moment of fear was the most intense feeling of uncertainty I have ever had.
If i would have been in 30 ft it might have been a lot worse.
this story is filled with rookie mistakes and bag circumstance, but to me, it highlights how one can not realize that one small risk at the end of a dive is really added to the entire rest of the dive. So my poor judgement on several small decisions (fight current underwater)(take two bugs on one dive rather than doing another dive) could have been dangerous. I know I would have been much more conservative in 35 fsw or even 25fsw
for what it is worth...
