Earlier this year, I bought my youngest son a new Calypso to do his Open Water training with. His first time in the pool with it, he complained about the plastic second stage and had me take one of my old USD metal seconds and put it on the Calpypso first. His complaint was in two areas: the plastic second gave him dry mouth and the exhaust tee was too narrow, causing his exhaust bubbles to pass directly in front of his mask. That got me to thinking and I've been looking at modern regulators, from various manufacturers, to look at their exhaust tees. It seems that modern regs are plagued by narrow exhaust tees. What gives? Why design a reg without an adequate exhaust tee?
