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 youâ€™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.
