■Underwater Slates and Notepads

Slates or notepads are used underwater, and are made of waterproof paper or plastic. They allow for us to communicate underwater when speaking is obviously impossible and gestures are limited, especially for detailed information.

■Log Book

We use the log book to record our number of dives, dive time, air usage, water temperature, and so on, as well as our personal experiences, all in journal form. Required at resorts and such when diving as proof of experience, please make sure to maintain your log book. Many people personalize their books with illustrations and stickers – your enjoyment is OK!

■First Aid Kit

Most instructors and dive shops keep a typical first aid kit prepared, but since moist skin injures more easily than normal, it is useful to have antiseptic, bandaging, and such ready for use. It is also important to include all necessary emergency contact numbers.

■Spare Kit and Tools

Items such as mouthpieces, mask and fin straps, and o-rings - all usually rubber or silicone-based - can tear, so it is a good idea to bring spares along with basic repair tools.
