Hunt away herons and other invaders
Herons are a burden for every pond enthusiast. Colorful fish stand out and are easily caught by a heron. To protect your fish, you can use a heron hunter like the Laser Guard van Velda. You easily mount the heron hunter about 25 centimeters deep into the ground and then connect it to the power supply with a plug. Now your pond is completely protected against herons and other predators.
Light flashes, laser beams and sounds
The heron hunter automatically detects a movement with his sensor and will respond immediately . This can be done in three different ways. The Laser Guard can react with flashes of light through which the heron will fly away immediately, or through the use of a laser beam. A laser beam is generally less annoying to people compared to a flash of light. Finally, use can be made of a natural way of chase away, namely by the sound of a poison frog or barking dog.
