The Compacta mould is a superb tool for loading method feeders with the same amount of bait every time. Hold the feeder mould in just one hand, while your other hand loads the cavity and presses down the feeder, then simply press the release button and drop out a perfectly formed loaded feeder into your palm! It loads Middy Gripper SG method feeders and other brands perfectly and its ergonomic one-hand release design is brilliant.
