This is the garden watering system that allows you to independently program two hoses from a single hose bib up to three times per day, per line, providing you with precise control for your preferred watering program. The simple three-button control allows you to program either one or two hoses for a specific watering cycle from one minute to 23 hours, and you can set your watering routine seven days in advance. The timer's patented circuitry is completely sealed and waterproof, and a built-in washable sponge filter traps contaminants that can clog or damage valves. Requires one 9-volt battery. 11" H x 10" W x 5" D. (4 lbs.)
