No we are not screwed
Drifting on the surface, no boat in sight, fog rolling in. One of the other divers said, "We're screwed, the boat still thinks we are on the wreck".
I responded "No we are not screwed" I took out my Nautilus Lifeline and let the boat captain know we bounced, and our GPS position. We soon saw the boat and talked them right over to us. The Lifeline saved our bacon.
