@Diver0001's story makes me think about the emphasis from my training on situational awareness. The fact that Diver0001 noticed an exit and took note of it was probably a really important aspect of this dive ending well. On one of my training dives I was tasked with sharing air and getting my buddy out of a wreck. This basically just entailed just moving from one interior room, through a few snags and an opening to the outside. My buddy was in side mount, so I turned him sideways to get him through a narrow doorway. Not a big deal and we successfully maneuvered out. Back on the surface, my instructor asked me why I didn't just take him through the big opening directly above me. Doh!
