We’re swimming fast. Too fast for my liking. I’m taking heaving gulps, and I know my tank won’t last very long if we don’t slow down soon. Just as I’m about to stop and risk losing my group, we hear a rapid series of bangs coming from our dive boat in the distance. Our guide, a lithe Indonesian with pistons for legs and bottomless iron lungs, points into the blue and somehow quickens his pace.
