o.O You can just buy a mouthpiece and replace it on any reg? I asked my instructor if that was possible and he said no. If I could just get a mouthpiece that would be awesome, I’m sitting here thinking of getting my own regulator to bring lol. It’s not so much the normal germs I’m worried about, it’s the people who throw up in them after getting seasick or like LatitudeAdjustment said, them not getting cleaned great after in "fresh" water. Listerine - good idea!
