The Dive wRites Notebook combines our 28 waterproof page notebook and graphite pencil with our ballistic nylon notebook cover. Inside the notebook cover are 3 non-slip pencil sleeves and a non-slip pocket for a survey compass. The back cover pocket is clear to allow easy visibility of dive tables or check lists. Contents of the notebook are kept secure by a hook-and-loop flap on the notebook cover. A 1 inch plastic d-ring allows the notebook to be clipped off inside a pocket for extra security.
