NAVIGATION CLASS: Today I started a class on underwater navigation. I'm taking this class with Chris a new Divemaster that is just going some specialties. We tried to learn how to use a compass and a little device that aids in mapping or tracking. We had a short classroom session and then started some practiced exercises. We were both pretty clue less and Peter (the head Instructor) had to get us started. Rather than start out underwater, we just did an above water exercise to MAP the dock system. After a rough start, I finally figured it out and did pretty well.

We went into the water and took a 30 meter tape with us. We laid it out under water and used weights to hold it in place. Then we swam from one end to the other at least twice to measure the time it took, the number of fin strokes it took and the amount of air we used. These measurements are used in navigation. The fin stroke count is the most accurate and we'll practice using it next week.

Tonight I'll eat at the Barracuda (the attached restaurant) and then watch the jam session again. Tomorrow will be a fun dive in the afternoon and relaxing. Monday is the stress test that I MUST pass.
