In some situations, for quiver/ feeder fishing, you can sometimes replace the feeder with a sinker.
If the fish are eating less, do not stuff the bait with a feeder, it is preferable to use a sinker to propel the rigging.
The branch sinkers are available in a matte black finish which is very discreet. The square shape, for excellent stability at all types of bottoms, including sloped bottoms.
