The Velda Pond Guard protects your pond fish from cats and herons by means of
glaring flashes of light and the penetrating sound of a bird of prey.
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 a bird of prey. Result: the heron or
cat takes flight, not to return to this pond in a hurry.
