This is a specialized organizational tool used by divers to compile and safeguard records of their underwater experiences. It comprises a binder, typically constructed from durable, water-resistant material, designed to hold log book pages. An example would be a three-ring binder specifically sized to accommodate standard dive log sheets, often featuring pockets for certification cards or other relevant documents.
Maintaining a detailed record of dives serves several crucial functions. It allows divers to track their accumulated experience, analyze dive conditions and performance, and plan future dives more effectively. Furthermore, a well-maintained record can be essential for demonstrating experience levels when pursuing advanced certifications or participating in certain dive activities. Historically, these records were simple notebooks, but the advent of standardized dive logs and readily available binders led to the current organized system.
