Florida Scuba: Molasses Reef (06/28/09)
After our deep dive on the USCGC Bibb, we used our second tank of nitrox (31% oxygen) for this very shallow dive to a max depth of 34 feet on Molasses Reef. The nitrox helped with fatigue and with a strong current. The current during our stay, we were told, was very unusual for Florida. Even so, it was a beautiful dive amongst beautiful animals and other ocean life.
Even though this was a pleasure dive, Laszlo and I practiced kick cycles and compass navigation in anticipation of our navigation dive for our Advanced Open Water certification.
Total bottom time was 52 minutes and I went from 3400 PSI in my tank to only 1800 PSI. Breathing nitrox definitely helped us consume less air, though the shallow depth also helps.
