In the late 1980s, the irrigation company Hydro-Rain introduced the first "hybrid" controller design, called the HR-6100, which combined electronic programming with a visual programming interface involving a single selector dial. Many companies followed with similar designs, such as Rainmaster, Griswold Controls, Toro, and Irritrol. Other, less-common systems involve fluid-filled hydraulic tubes to open or close the valves.
