The Problue Deluxe Underwater Notebook has a heavy duty nylon fabric cover that is closed using a Velcro tab and elastic cord that is stretched across the notebook. The deluxe notebook uses waterproof paper that can be scrubbed clean and re-used and is tear resistant.

One inside cover has four elastic pencil holders and the other inside cover has a Velcro sealed clear Perspex pocket. The notebook is bound by four heavy-duty plastic zip-tie cords to ensure the notebook pages are incredibly secure. The bottom of the spine has an elastic loop that allows the deluxe underwater notebook to be attached to a lanyard or clip. It also comes with a pencil that can be attached to a long elastic cord.

The Problue deluxe notebook has a clear Perspex outer pocket with an inserted chart to allow divers to manually calculate times if necessary and for extra storage.

The Problue Deluxe Underwater Notebook is 12cm X 19.8cm in size.
