This project responds to the need for having a functional dive log. When I became a certified diver, I noticed that many logbooks didn't offer me the necessary information. Most of them included several sections that were irrelevant for my dives (e.g. photography equipment). Additionally, some books were too big to take them on a trip comfortably. So, it all resulted in big pages that looked half empty and useless. Therefore, I created a reduced and easy-to-use design that could help divers track immersion data quickly.
