'Dry' snorkels and purge valves?
I'm starting to play underwater hockey and find that regular snorkels get a lot of splash with surface swimming (or lots of commotion on the surface) when I'm breathing hard and have no time to deal with water in the mouthpiece.
I've tested a dry snorkel out and it seems to stop all surface splash, GREAT... however with every dive then blow (clearing) I find a little water remains in my mouth piece. Thus when I take my breath, half a mouthful of water comes bubbling in with the new air, stopping everything for me. QUESTION: Is this little bit of water there because the water doesn't fully exit through the mouthpiece purge valve with a blow? During a blow, does any water also exit the 'dry' valve at the top of the snorkel? Maybe I just have to blow harder?
QUESTION: Are there 'dry' snorkels, without a purge valve, which allow a full blow clearing? Perhaps regular snorkels, with just a rudimentary splash guard which only do a half-job of splash protection, but still allow for traditional blow clearing and no purge valve business?
Provide some product examples if you can! (For me and future readers)
Any comments on this?
