The one thing I did notice is that blow out is harder and often requires a second blast to get some drizzle out if the bottom. The problem ca be eliminated while snorkeling by using the "puff" method. When on the surface on the way to scuba, however, this can't be done. I would think that prolonged snorkeling using only the blow method would cause greater fatigue. Brian Atkins ...{attunix, hao, allegra, ucbvax}!nbires!atkins NBI Inc., P.O.
