Simply blare the horn using a momentary push button switch and the cattle will instinctively learn that it is time to feed. The siren also speeds up feeding times since you can sound the siren when you enter the fence and the cattle hear it from yards away. The sirens are not completely waterproof but will stand up to the weather for a long period of time. The sirens sound will travel 1 to 1.5 miles away.
