Diver's Notes

Conditions at Hanauma Bay were less than ideal. Visibility was very bad, spent a considerable amount of time regrouping with buddies than sightseeing.

Aquatic life was abundant and many fish were of good size. Reef formation was amazing near Witch's Brew.

For our exit, we passed through the south channel buoys and followed the cable out to the reef. On our return, we missed the channel buoys and fought with the waves and shallow rock. We went back out into the bay to realign ourselves with the underwater cable.

Tank pressure was shorted to start. Tank was only filled to 2200 PSI. (Credit that to rapid hot filling.) Should invest in a tank checker!
