TDS underwater writing slate

TDS dive slate with 40 waterproof pages and a Cordura cover with small pockets, includes graphite pencil. Allows for writing in and out of the water.

The inner notebook features a table on the first two pages where emergency plans or plans for various gases can be placed. The rest of the pages are blank to allow for any desired notes.

The book also features two external elastic bands that allow it to be secured both horizontally and vertically, preventing accidental opening and making it very easy to remove even with thick gloves.
