Product Information
The Hollis Underwater Notebook is a waterproof writing kit for divers who need to record information in the water, with waterproof pages that stay legible when wet and an included pencil so you can write at depth. Hollis lists it as SKU 220.8122 in its General Accessories range.
Who it is for
It suits divers who record dive notes or survey data in the water, or pass written messages to a buddy. The pages can be written on in the water, so the notebook also works for communication between buddies.
