More from Cozumel - Underwater Navigation Class
This morning I studied for my course and this afternoon I did the underwater navigation segment. I learned that I do 28 kicks in 100 feet, to navigate by bottom features and to measure distance by walking along the bottom on my hands and counting the hand strides ( also 28 per 100 feet). Tomorrow I do a deep water dive and follow that with a fish identification dive. More studying.
