Fish ID Guide for the British Isles & Northern Europe for divers and snorkellers in the form of a waterproof slate. Particularly helpful guide to those diving Cornwall to help identify the diverse array of marine life thanks to the Gulf Stream lapping the Cornish coastline.

Take it underwater and spend hours fish spotting or, keep it in your dive bag for post-dive logging sessions.

Our opinion: Great for explorers of the undersea world.
