The easily programmable Gilmour Electronic Water Timer saves you time, money, and water all season long. Choose the start time, frequency, and duration, from 1 to 360 minutes, and let the timer do the rest. Its large LCD screen makes programming a breeze, and a safeguard automatically turns the water off when the battery is low. The rain-delay feature even lets you choose how long to delay watering after rainfall, and an on/off function allows you to water manually without removing the timer. Runs on 2 AA batteries (not included).
