The Pond Guard Shuffle protects your pond fish against herons and cats by means of glaring flashes of light and penetrating noise of animals of prey, including an ultrasonic sound which is inaudible for men.
By installing this unique Pond Guard on the edge of the pond you will trigger an immediate flight response that will stop cats and herons getting close to the pond and so catching all your valuable fish.
The concept is ingenious, yet simple:
at an angle of 180° and within a radius of not more than 25 metres, a movement sensor will detect an approaching heron (or cat) and immediately emit a number of glaring flashes and the penetrating sound of animals of prey.
the heron or cat takes flight, not to return to this pond in a hurry.
