On alot of my vacation dives there's a set time we will surface, regardless of what's in your tank. I don't like it but I don't make a fuss. I've been in large groups where when someones tank gets low they send them back to the boat & everyone else continues on. I've also seen when one person gets low - were all done. Usually my buddy (boyfriend) sucks air like a madman. But the last time we dove, it was me. Not sure what my problem was.
