Many divers already know the advantage of carrying a slate, for those moments when hand signals are just not enough. Expanding this concept to carrying a whole notebook brings a new dimension to written communication underwater. You can write down conversations, invaluable when complex decisions need to be made, instructions if teaching, survey information, decompression schedules, in fact, anything you’d use a piece of paper for on the surface.
The notebooks come with a plastic pencil which will not split on immersion, like normal wooden pencils. A clear window allows frequently used information like decompression tables to be viewed quickly. They come in a tough Cordura wallet, with 50 pages of plastic paper which can be refilled when full. A double ender to clip into your pocket is also included in the price. They slide neatly into a suit pocket, and are a very nice piece of equipment to have.
