Fish Stringer Holder

I have had the problem of wading far away from the boat, catching fish, and then returning to the boat only to find that my stringer is half a mile away. Could y'all give me info on how to make a secure holder for your stinger to your wade belt? or buy one... I was thinking about a 1"x1"x5" block of wood with a bored hole in the middle (then sealed) and a spot for my 2" wade belt to run through. Anything helps, thanks and God bless.
