The Ultimate Diver's Log Book (Mini) is the colourful 50-dive log book. This is a thoughtfully-designed, book-format scuba diving log book. It contains boxes for all the essential details a sport diver might like to record in a clean simple layout. Each dive gets a two-page spread to record all the dive site information. You can also log kit details you might want to refer to again. There is scaled graph paper (time/depth) to record dive profiles (or use however you wish). Almost a whole page is available for sketches, notes and stamps. As with the larger Ultimate Diver's Log Book there is the innovative Visibility Scale - a range of colours from which to pick the water colour and compare with the visibility. There is also room at the front for personal details and lined pages at the back for additional notes. Two colourful pages per dive. Space for 50 dives. Log depths, times, buddies, gases and consumption. Visibility Scale. For recreational divers this is the Ultimate Diver's Log Book (Mini). Slightly shorter and narrower than it's big brother (Ultimate Diver's Log Book: ISBN 978-1-909455-10-6) but the same great quality.
