That's a great starting point! Here are a few ideas:
1. A new geocaching course: Research new places to go geocaching in your area, or consider planning a weekend trip to a destination that is known for geocaching. Make a scavenger hunt out of it by hiding small gifts or notes in some of the geocaches you find.
2. A geocaching tool kit: Help him upgrade his gear with a bundle of geocaching essentials such as a GPS device, tracking software, and geocaching book.
3. Geocaching-themed jewelry: Consider a personalized geocaching keychain for your husband to display his love for this hobby. You can have it custom made with his name or a special message to commemorate your anniversary.
4. A geocaching adventure book: Create a photo book filled with your husband's favorite geocaching stories, with pictures and notes from all of the caches he has found.
5. A travel bug: A travel bug is a small object that geocachers can leave in a cache and track its journey. You can create a personalized travel bug with the anniversary date or a special message for him to track around the world.
Or you can get him a star map with the date of your anniversary.
