That's a great hobby! Here are some gift ideas:
1. A metal detector: If your girlfriend doesn't own a metal detector yet or is looking to upgrade her current one, it could be the perfect birthday gift for her.
2. A metal detecting kit: A kit that includes a metal detector, digging tools, headphones, a carrying bag, and a book on metal detecting would be a thoughtful and practical gift.
3. A book on metal detecting: If your girlfriend enjoys reading, a book on metal detecting could be a good choice. Look for one with tips and tricks, techniques, and stories from successful treasure hunters.
4. A metal detecting app: Consider gifting her a subscription to a metal detecting app that provides maps, sites, and tips for finding treasure.
5. A personalized digging tool or carrying bag: Consider getting a digging tool or carrying bag personalized with your girlfriend's name or initials. This is an excellent way to make her feel special and show that you appreciate her hobby.
Or you can get her a star map with the date when she was born.
