Years ago we did same with a buds fishing rig, we used an old chain, get one not too heavy and if
you snag on a big stump or rock ledge have it where you can untie the knot with loosing alot of line....
Older cheap chain is easy to find, not sure how big a boat or rig your running, a small 10 ft pc should
do fair enuff? play around with different items, key is to slip on the bottom,,,,,, if thats possiable unless
your fishing mega deep waters?
Teach a child to fish, and you get them hooked for life! then the memories begin!
