How about a scuba diving-themed gift? Here are a few ideas:
1. A scuba mask and snorkel set - this is an essential piece of equipment for any diver, and your grandson may appreciate having his own set.
2. A waterproof dive watch - these watches are designed to withstand the pressure of diving and can be a great tool for tracking dive time, depth, and other vital information.
3. A voucher for a diving lesson - if your grandson hasn't learned to dive yet, this could be a great way to introduce him to the sport.
4. A book or DVD about diving - there are plenty of books and documentaries out there that explore the world of scuba diving, from travel guides to underwater photography tutorials.
5. A gift certificate for a local scuba or diving store - this way your grandson can pick out his own gear or equipment to suit his specific needs and preferences.
Or you can get him a star map with the date when he was born.
