A sturdy plastic slate for recording information underwater.
This A4 sized slate giving ample room to record everything you see on your dives, however big your writing is underwater. It has a clip to attach to your BCD and a pencil that is securely attached so it doesn't float away. The slate is also printed with a checklist of things to record and a scale.
Each slate also includes a Seasearch "waterproof" pencil made from recycled DVD cases.
