We had harnesses on our dipsey and on our inline boards with 3oz weight.Those two inline boards with harnesses did not catch one keeper walleye last week.But the dipsey on 3 setting with the harnesses got like 7 keepers.I believe the turbulence from the dipsey attracts the fish better than a sinker.
I also believe that its much faster to check the dipsey lines for shorts or trash than the boards.I can bring in and reset a dipsey before I can even get a board to the boat.
