-A unique feeder designed by Delphin in a unique MAGMA design.Base of the feeder is a square basket made of a solid wire. This prevents overpressure during filling with feed, which is perfectly released in the water. There are four pointed protrusions at the bottom allowing the feeder to stick  better to the bottom and thus limiting its movement caused by the hungry fish or the river current. It is equipped with a swivel on the extended moving part for comfortable attachment to the feeder assembly. It is available in various weights and three sizes: S, M and L. Every fan of the feeder can choose the right one for the given situation and water type.
