The Crop Gard is the first of a new series of bird repelling sound units which use a combination of several completely different and distinct sounds.
Crop Gard has three major sound categories:-
These sounds can be played sequentially or in a completely random order. We recommend the random order to present a more chaotic sound to the birds, which is harder to adapt to or accept.
with all Bird Gard sound generators, the
Gard is fully automatic. It has a light
sensor that can be set with the flick of a switch to DAY, NIGHT, or
24-HOUR operation. There is no need to physically have to go and turn
on in the morning and off at night, it's automatic.
Crop Gard uses only artificial non-natural sounds, sounds which no bird has ever heard before. The Crop Gard has 4 speaker output terminals. It be connected directly to a 4 way (360 degree) speaker. It also can be used to run a sonic fence (a series of speakers 30m apart) made up of as many as 8 speakers thus forming a wall of sound 210m long.
Due to the Crop Gard having several different sounds, it's like having several different individual sound units all placed in the one position and all working at once. This definitely produces a superior result and covers a greater range of bird pest species. When a grower has a large number of different bird species eating his crop, Crop Gard is most often the best choice.
