I am not a pro, but I have more dives than the dude I took out. It was his 2nd dive. So I played leader, only every time I would turn around to see if he was at my fins, he was way behind and at the bottom trying to stay bouyant. He was kicking up silt, and constantly looking at his air. I lost him so many times and had to go back, that soon I was running low on air! After that, I decided, no newbie buddies!
