Rather than tie eight knots and have the boat out of control, tie these ahead of time at home and keep them stored and ready to use on a tackle buddy. Half of Walleye fishing is preparation. If your fishing around other boats or shallow areas you don’t want to be floating out of control.
Better yet, slip my slip sinker bottom bouncer, it only requires one knot to your leader. It is snagless, fully weight adjustable, won’t spin and has many other benefits.
