The Pro Plus is a junior version of the Crop Gard. It has 2 major non-natural harassment sounds. When these sounds are combined, they are very effective against most common bird pests such as:
Cockatoos, Crows, Musk Lorikeets, Rainbow Lorikeets, Scaly Breasted Lorikeets, Port Lincoln Parrots, 28 Parrots, Rosellas, Silver-Eyes, Starlings, Black ducks, Cormorants, Crows, Leatherheads.
Designed principally to repel birds from small areas and domestic bird control, the Pro Plus comes as standard with 2 remote speakers (each with 30m cable). You can extend the distance covered by the two speakers to 60m by daisy chaining 4 speakers.
The Pro Plus Distress is another version of the Pro Plus. This unit is similar to the Pro Plus in all aspects other than it uses only bird distress and predator calls instead of harassment sounds. Eight individual birds are recorded. Six are actual distress calls and the remaining 2 are predator birds, being falcon and kestrel.
Both these units run off either a 12v battery or 240v mains power.
