Birds perceive the Agrilaser Handheld’s laser spot as an approaching physical danger. Once they perceive the laser spot, they fly away in search of safer ground and, in contrast to conventional methods of bird deterrence, there will be no habituation. After consistent use of the Agrilaser Handheld, birds will perceive the controlled area as unsafe and will not return. The Agrilaser Handheld is best suited to outdoor bird dispersal over long distances. Use to protect areas such as golf courses, fields and large scale roofs. Bird Control Group dedicated years of research to develop the ultimate laser beam. This goal was achieved through the application of a combination of highly precise optics, filtering and light frequencies. The result is exceptional performance in bird repelling over long distances. Red dot sightTo make operation over long distances more accurate and safe, the Agrilaser Handheld is equipped with a red dot sight. The sight makes it possible to accurately aim the Agrilaser Handheld at a desired target before activating the laser. Key lock systemTo prevent unauthorized use of the equipment, the Agrilaser Handheld is equipped with a key lock system. DurabiltyThe Agrilaser Handheld has a robust design to ensure effectiveness in demanding situations. The shockproof cover protects the laser from damage from falls and dust exposure. Therefore, the laser can be used in a wide variety of environments.
