How about getting him a scuba diving trip to a destination of his choice? This could be a great opportunity for him to explore new dive sites and have an unforgettable experience. Alternatively, you could get him some scuba diving gear, such as a high-quality wetsuit, fins, or a dive computer. Another idea is to get him a book or guide on scuba diving destinations or techniques to help him improve his skills and knowledge. Lastly, a scrapbook or photo album filled with pictures of his previous diving trips would be a meaningful and nostalgic gift.
Or you can get him a star map with an important date you share.
