Wed, April 24, 2013 Dives: 2 Bottom Time: 63 minutes Max Depth: 36-40ft/11-12m Avg Viz: 81-90ft/25-27m Water Temp: 71-75°F/22-24°C Weight: 14 Exposure Suit: Fullsuit - 5/4 (Hood, Gloves, Boots) Tank Type: AL - 80cf/11L Gas Type: Air Dive Type: Boat, Training Dive Buddy:   Nate Jonson Koko Craters Oahu, HI Water Type: Salt Entry Type: Boat

Underwater Navigation Specialty. On the first dive I had to use a compass and swim 20 kick cycles due north, then make a 6 point turn with each side having 20 kick cycles ending up at my starting location. This was very difficult with the current, but I finally managed to complete it. I also had to pick an object on the sea floor then take two compass bearings on it so that I could locate the same object again on a later dive.


On the second dive I had to use a compass and locate objects on predetermined headings that were given to me counting kick cycles between the objects, while mapping the area and objects that I found. At the last object I had to use reciprocal headings from each object to find our way back to the boat
