A lot of spearos use snorkels with some sort of purge. The companies like Picasso, Omer, and Cressi all list only simple (non-purge) snorkels in their catalogs.
Is there some overriding reason to choose one or another?
I'm currently using a simple Mares snorkel and a Cressi Sigma (purge). Both work, but the Cressi seems easier to clear at the end of a dive.
