Thought he was talking about that black plastic thingy you attach decoys to and just roll up.
Those things would be pretty sweet on divers in deeper water if they work as advertised. Beats winding up 4 dozen individual decoys.
You clip them on and just roll it up. It’s alright for deep water situations only one anchore. I feel like it makes the decoys loot right and nervous. Never had an issue killing them over long lines and they are easy and quick.
