Intended for use with previously purchased mechanical scare cannons. Modernize any standard mechanical cannon with this conversion kit. Features include: built-in timer, multi-shot, automatic, random, on-demand modes, and hose facture protection valve. Choose between 1, 2, 3, or 4 shots each interval. In automatic mode, the cannon can be set to detonate every 1, 2, 3, 5, 7, 10, 13, 16, 20, 25, 30, 45, or 60 minutes. There are three random modes to eliminate animal tolerance by randomly varying the time after each shot series. It also allows on-demand detonation by purchasing the corded pushbutton controller or the hand-held radio transmitter/receivers.
