Last week while doing our morning drop-off dive at Coco View in Roatan I had a learning experience.
At Coco view the second boat dive is a drop-off dive on either Newman’s Wall in the southwest or Coco View Wall in the Northeast side of the channel. You then swim to shore. On this dive we were dropped at Newman’s.
We, group of 4, were coming in with the wall to our left and were at about 90 ft. Somehow, we crossed the channel and were headed out Coco View wall. Bad mistake in that we all assumed the wall was still on our left and didn’t check our compass heading – lesson #2, group consciousness isn’t always right!!
We came up to 45ft at 750psi and surfaced at 500psi, but had gone a fair distance down Coco View wall. I was down to 250psi after the SS.
What would have been a simple surface swim back in the other direction became a pain in the ^%^%^ back swim rafting on the BCDs.
I will never dive again without a snorkel!
I think the greater lesson learned here is that navigation and always knowing where you are is far more important than having a snorkel.
Perhaps, but the OP very openly acknowledged that good navigation is important. He also said that group consensus can be misleading.
He just made the point that another important lesson he learned was to always bring a snorkel to deal with the hassle of a long surface swim.
A very reasonable precaution, I'd say, that comes in handy quite often for many of us who shore dive in the ocean.
I'm always reminded of the scary episode of laryngospasm that was suffered by a ScubaBoarder who choked on some water while on the surface. If I remember correctly, his throat closed up and it was so long before could draw a breath that he almost blacked out. That can happen to anyone.
I also remember my own experience in water so choppy that it was difficult to avoid choking on the chaotic water. Just stuck my snorkel in my mouth and was able to easily watch for boat traffic until my boat could pick me up.
I certainly don't underestimate the risk of rough water or overestimate my ability to cope with it.
I might add that wearing my snorkel on every dive has never proven to be a liability to me. In fact, only twice has it been in the way at all and that was on two occasions when I removed my gear to release an entanglement. Not a big drawback in my book.
Quite often I find snorkelling a real pleasure at the end of a shore dive.
Sometimes I've found having a snorkel invaluable....
