This compact underwater slate will fit into most BCD Pockets, yet has plenty of room for taking notes, communicating with your dive buddy, or writing down skill performance when training. Whatever your writing needs are, this slate can get it done. Unlike more conventional dive slates the WR6 pencil has replaceable lead for years of continued use. Dolphin Tech's Underwater Slate is also equipped with a corrosion resistant locking gate clip and perhaps best of all, a retractor with lockable mechanism so you don’t have to struggle to prevent it from being pulled back while writing. The WR6 is up to the technical diving task at hand.
