Why do divers carry a snorkel? Don’t they have air already?!
If you’re not a SCUBA diver this is an understandable question. Why would we have a snorkel if we’re already carrying air in a cylinder on our backs?
And, if you are a diver do you ever ask yourself this question or have you ever left your snorkel in your dive bag (you don’t have to admit it out loud… just let the voice in your head do the talking).
The answer to the first question is, of course, we do have air but there are some good reasons for carrying a snorkel as a SCUBA diver and some problems as well.
