Thinking with ds and his interest in gems/rocks etc and all oddments he finds on his way when out lol that I might buy him a metal detector for his birthday next month.
Saw a man on beach 2 days in a row and ds was avidly following him with his spade to dig treasure lol
Saw a National Geographic one for only £20 and wondered if that would be a good start off.
Are they easy to use? He is going to be 7
