More on Wet Notes
Wet notes are essential tools for divers who need to communicate complex messages, record navigation details, or take field notes during underwater research. Made with waterproof materials like plastic or waterproof paper, wet notes allow divers to write using pencils or specialized markers. They typically feature a cord or bungee loop for secure attachment and may include plastic pages, compass headings, emergency plans, or pre-printed dive slates. Cave and technical divers often rely on wet notes for gas plans, turn pressures, and decompression schedules.
