Sunday, 16 July 2019, 2nd OW Dive on the Swiss Cheese Reef

During our 99-minute surface interval, Johnny took the final exam and we went over the dive tables but he did not take those tests. We geared up and got in the water. We swam out to the buoy and descended at 10:13 am. We swam to the Wrap Around Ledge, swam across the rubble and settled in on the sand flat to perform the skills. We did the removal and recovery of the regulator and the mask. We performed a stationary alternate air source, a cramp release and weight removal and replacement. We performed a fin pivot and then we hovered. We spent 20 minutes on the skills listed on the OW slates. Johnny had trouble performing only one:  the hover.

Graysbys (Cephalopholis cruentatus)

After the skills, we swam East to the Rockline, to the tire and then to the Crescent Moon Rock. We turned ENE and swam to the Giant Barrel Sponges and then to the Staghorn Coral where we saw Graysbys (Cephalopholis cruentatus)

Spotted Scorpionfish (Scorpaena plumieri)

and Spotted Scorpionfish (Scorpaena plumieri).

Giant Anemone (Condylactis gigantea)

We went East to the Sectioned Rock and I photographed the Giant Anemone (Condylactis gigantea) that grew there.

Bar Jack (Caranx ruber) 

At the Sectioned Rock we turned North and followed the Reef. I got a nice picture of a Bar Jack (Caranx ruber).
