BCS, thanks for clarifying your thoughts on snorkels. I was wondering about that.
You make a really good point i.e. OOA grabbing the snorkel. And although I've never witnessed it, I haven't been helping out with classes very long, and I'm sure it's happend more than once. So point taken.
I didn't like how it felt hanging off my mask, so I stopped using it for rec diving.
I was helping with a class and the instr told me that it's a skill that the students must do, so I have to carry one also. But then said, instead of swimming out on your back, use that time to snorkel out and look at what you're missing, find stuff that you can explore on the way back in. And it help get your face used to the cold water. I thought he made a great point, so I keep it in my cumberbun now when I dive and holy cow, I have found some neat things. We can switch out drop down and check it out, them pop back up and continue out to the bouy.
