Mitch and Nicoles second and third dives


On the surface, I had suggested to Nicole that she treat the mask removal and replacement skill as 3 separate and smaller skills:  1. removing the mask,   2. creating positive air pressure to keep water out of her nose and re-seating the mask, and 3. clearing the mask and securing the mask band.  We talked about it and she went through the skill in her mind. then we descended. On the bottom, she removed her mask, breathed through the regulator, then replaced her mask and cleared it. She paused and then adjusted her mask strap.

Once they each demonstrated mastery of the mask removal and replacement skill we moved on through the other skills, including removing a weight and replacing it underwater and removing the BCD and replacing it underwater. They each performed the various skills but Mitch apparently lost one of his weight packets not too long after performing that skill. Oddly, he did not notice that he had suddenly lost 6 pounds, suggesting that he might be a little heavy at 12 pounds. It was not until he was putting his gear away that he discovered he had lost one of the weight packets.

Dive time was 31 minutes, maximum depth was 23.8 feet and the bottom temperature was 77 degrees.  My SAC was 21.71 psi/minute and the RMV was a more respectable 0.46 cubic feet per minute.
