The Dive Rite Executive Slate has six, compact erasable slates held together by a stainless-steel-split-rings. A cord with sleeve stows the attached solid carbon stick pencil and attaches to the slate with a corrosion resistant spring-loaded gate clip with swivel. Small enough to fit in a tiny pocket or grouped with other larger items, the Executive Slate is ideal for note taking or as a back-up communication device. Being able to communicate underwater can really make diving more fun. Having something to write on can cut down on playing charades underwater and get to the point. Slate is made from durable plastic. Slate measures 3.5 x 5" (8.9 x 12.7cm) and weighs 2.8 oz (79.4g).
