Man I'm learning a lot here Eugene! Love to learn from a pro! If you ever end up with an F-18 in your toy box, I'll fix it...(you buy the parts).
When you say "foot pocket fins", are you talking about these?
But I'm having a hard time figuring this one out:
I take it the lower protuberence is a purge valve, and the other end goes in my ear?
Or does the mouthpiece section extend down my chin, with the breather tube going up thru my mask strap? And you can crawl and butterfly with it?
Come a long way since my first snorkel with the ping-pong ball that tried to kill me.
Looks like I'm going to learn to swim all over again.
