The Halcyon Diver’s Notebook (Wetnotes) is an essential communication and planning tool designed for both technical and recreational divers. Sized to fit comfortably in any BCD or drysuit thigh pocket, this underwater notebook provides far more space and versatility than standard plastic slates.

Encased in a rugged cover made from the same heavy-duty ballistic nylon used in Halcyon’s BC wings, the Diver’s Notebook is built to withstand extreme dive conditions. Whether you are logging decompression schedules, taking underwater photography notes, mapping wreck features, or running survey lines, this notebook keeps critical dive information organized and accessible.
