The advanced-design IBOC100 and new remote-controlled IBOC300 are highly reliable, battery-powered, valve-mounted irrigation controllers. Easy to install and use, they are specifically designed to provide automatic valve operation in irrigation areas where a hardwire connection is impractical. Both models also are ideal for converting existing electric irrigation valves to independent battery operation, and they can be used to temporarily replace a solenoid if a broken irrigation valve wire cannot be fixed immediately.
