Snorkel: Most experienced divers insist that snorkels have no place in scuba diving. Some, however, insist that on surface swims or long waits for the boat, they can be useful. If you want a snorkel that'll last you whatever opinion you form, look for one that can be folded or rolled up compact so it can be stored in a pocket.
No matter WHAT your instructor may have told you, you do NOT want a snorkel clamped to your mask. A snorkel attached to the mask is a snag hazard that can flood or even remove your mask, and is widely considered a sure sign of a novice diver: In a poll on an Internet forum, results were:
- Snorkels are pointless, I won't dive with someone who takes one - 1 vote
- Snorkels are pointless, but I really don't care about it much - 12 votes
- Snorkels can be useful sometimes, but I don't take one - 20 votes
- Snorkels can be useful sometimes, so I take one stowed away - 9 votes
- Snorkels can be useful sometimes, I have one readily accessible - 9 votes
- Snorkels are vital dive gear, I won't dive with someone who doesn't have one - 1
So, two thirds of divers who voted do not even take a snorkel. And of the one third who did vote for taking one, some posted the modifier that they only took them when a long surface swim was expected.
Examples of folding snorkels you could consider include Scubapro, Sherwood, and Technisub
