I made my own with a dog leash. I cut the chain into 4-5 strips around 6-8 inches long. I put them on a snap ring and attached to around 30 ft of trotline and wound it up on a buoy marker. Most of the time it will either knock the bait loose, or the chains will tangle in the hooks and you can pull it free. It will mess up the hooks, but that is nothing compared to the cost of a CB.
Cost = about $4.00
Set the hook first, ask questions later.
