"The ultimate casting feeders! Absolute Window Feeders are available in three body sizes so you can vary the amount of loose feed introduced. Simply add your loose feed, plug with a small amount of groundbait and cast. The 'window' in the feeder is thumb sized making the operation as simple and easy as possible while there is an internal ramp built in to the feeder to help the bait release. Small holes in the top of the feeder also help to release the bait.
