Sine he's coming up on his 14th birthday by now, I'd look at a decent navigation kit to give him a little more independence and responsibility outdoors
Decent baseplate compass with sighting mirror
Basic backup baseplate compass
"Be and expert with map and compass" by Bjorn Kellerstrom, or similar book
Headlamp with medium-long battery life and replaceable batteries. Kudos if it has a red light option to preserve night vision
Planisphere for night navigation
(optional) pocket monocular to glass routes.
Emergency whistle if all else fails. The Storm, Wind Storm. and ACME 558 whistles have reputations for carrying long distances through wooded areas. IME, whistle with distinctive trills tend to be more recognizable.
“He pointed out to him the bearings of the coast, explained to him the variations of the compass, and taught him to read in that vast book opened over our heads which they call heaven, and where God writes in azure with letters of diamonds.”
