Can't recall if I posted here back in 2011, but I have yet to have any experiences with panic. I have had numerous uncomfortable situations, due to such things as unexpected current, cramps (I am very prone). Fortunately, I have always remembered to "stop, think, act" as they say. Recently I was at a very benign site where right near the shore it dropped from 3 to 10-15'. Got to about the usual 4' or so to remove fins and exit, but I slipped out a bit, and my boots then couldn't get traction and sunk in the mud. Surfaced (only time I even broke the cardinal rule and added air to my BC, because you can't swim up without fins on and putting them on down there was not a great idea with all the mud I kicked up--didn't want to lose a fin), put the fins back on, exited better this time, and that was that. I did release air as I ascended to keep a slow rate--after thinking, this seemed the way to go. The only bad thing about NOT being in a really bad spot is you have no reference as to how you will react when panic is on the horizon. Maybe I'll get lucky and skate through until I'm too old to dive?
