Got to the State park by 8:05 am and was headed around the block to the beach by 8:15 am. Got in the water and swam out past the swim buoy to descend. Visibility was terrible: about 5 ft. I couldn't see the Big Rock. Even when I got down, I couldn't see the Big Rock. I swam around and found the old buoy pin and from there I found the Big Rock and headed South to the smaller rock, but ended up at the knee-high coral. Okay. From there I went 130 degrees to the sand sea and the dead sea rods. From there I went North to the counter-weight and then 130 degrees from there to the barren sea rod and then the green and red coral and finally to the knoll. I could hardly make out the ledge at the knoll from the tipped coral, but the sun came out and visibility got better. Still only about 10 ft, but better. Started exploring to the East, but got lost on the way back. Went South of the knoll, but recognized a small pile of large rocks with a very big Nurse Shark and came back at 45 degrees to find the knoll again. Getting low on air by this time. Played around on the knoll until I was down to 1,000 psi, at which point I headed back: 130 degrees to the red and green coral, then past the barren sea rod to the counter-wieght. Southwest to the dead sea rods and then 130 degrees across the sand sea to the knee-high coral, the smaller rock, North to the Big Rock and back the the beach.
Dive time was 143 minutes; consumption was 21.54 psi/minute at an average depth of 18 feet; SAC rate was 13.94 psi/minute; RMV was 0.36 ft3/minute.
