scubatoys:Actually I like the air powered noise makers... the Hammerhead... but if you get one... please - very short honk when you see something really cool you've got to show me. Not HOOOOOOOOOOOOOOOOOOOONNNNNNKKKK!!!! because you spotted the oh so elusive parrot fish.
NOOOOOOO! This brings back nightmares of a couple on a dive trip who constantly honked those things!
How do I talk through my reg? I just....talk! Some sounds can't be pronounced with something between your teeth. Stick your finger between your teeth and talk and you'll see what I mean. Even so, no one has any trouble understanding me. On the other hand, I find very need to talk underwater...hand signals work well enough.
