Quakers really don't ever say much, no matter what you do to them. Infact, once I heard about a Quaker man that was being robbed. He went and got his gun and walked in to the room and said very softly and politely to the man robbing his house "Friend, I would do thee no harm for the world, but thee standest where I am about to shoot."
Oh, quacker noisemaker? Like a sub duck? Do you want one that makes noise above or below? If above, I'd invest in a whistle. You don't need air in your tank to use a whistle. If below, Is ee your point. Was nice in class for my instructor to use to get our attention. Scubatoys probably has them. Otherwise ther eare several other board sponsors who probably have them, and all of them have "scuba" in the name and I can never remember the rest. Check out the "hot deals" forum and you should find links to their sites there. Several of them give discounts to SB members, but you might have to call them to get it.
