The GURDIAN 2 models operate with butane or propane gas, allowing them to make loud detonations and thereby protect crops by frightening away birds, wild boar and any other animal that damages them. These detonations may be the desired frequency, from every minute to every half-hour, and the loudness of the detonation can be adjusted thanks to its telescopic cannon, varying from 80 to 120 decibels. The area protected by our scarecrows is three to four hectares depending on the type of crop and type of land. The system is switched on electronically by means of a piezoelectric motor and the rest of the mechanism is mechanical, guaranteeing reliability and tolerance all meteorological inclemency. Our 50 years experience manufacturing and exporting these products allows us to offer you maximum quality and maximum efficiency in crop protection.
