$30 · Lee Valley Watering Timer

We installed a new watering system this summer, so no longer need this; it works perfectly. From the LeeValley website: With these versatile, high-quality timer, controlling how much and how often you water is a straightforward process. The dial-operated timer takes seconds to program. One dial sets watering frequency, with nine options ranging from every 3 hours to every 14 days. A second dial controls watering duration, with ten settings ranging from 2 minutes to 9 hours. A delay-start button postpones activation for 1 to 12 hours, so you don't have to wait for the right hour to set the unit. The digital timer's flexible programming makes it ideal for use in areas with daily water restrictions. With LCD display and easy pushbutton programming, it can be set to water on any or all days of the week, up to four times per day, for a duration ranging from 1 minute to 12 hours (in 1-minute increments). Manual override buttons let you water between cycles, or pause them, without altering the settings. It has a low-battery indicator, and it stores settings for 30 seconds while you change the battery.
