Protect your fishing pond against herons!
Because this pendant is constantly turning, this sunlight reflects in the eyes of herons that may come close to your pond. The bird is immediately put off by this and therefore has no chance to grab your fish from the water. Below you can see how the Velda Heron Stop Spinner applied above a pond. In addition, however, the hanger can also be attached to the balcony, so that pigeons are chased away.
