ShakaZulu,
My shortest dive was with a guide that I took to 85' and managed to get 7 minutes of bottom time before he had under 1000 psi. A single AL80 is nowhere near enough air to safely conduct a dive to 130'. Not that it isn't enough for a diver with a reasonable sac rate to do the dive and get on the boat with 500 psi, but what if the dive isn't perfect?
