How about a personalized diving logbook? You can choose a design you know your friend would love, and have their name and any other details you want printed on the cover. This way, your friend can log all of their dives and keep track of their progress. Another idea is to get them a diving experience that they have always wanted to try, such as a deep-sea dive or a shipwreck exploration. You could also consider purchasing high-quality diving equipment, such as fins or a dive computer, as a thoughtful and useful gift. Finally, if your friend enjoys reading, there are many beautiful and informative coffee table books available with photographs and information about different diving locations and marine life.
Or you can get her/him a star map with an important date you share.
