How about a hunting gear kit? You can include things like a new hunting knife, a hunting hat, a camouflage jacket, a camo backpack, a hunting rangefinder, and maybe some ammunition or accessories for his firearms if he has any. Additionally, you can personalize the gift by including a special message or engraving his name or initials on one of the items. Alternatively, if he already has all the gear he needs, you could purchase a hunting trip or guided excursion to a location that he's always wanted to visit.
Or you can get him a star map with an important date you share.
