"Saving water goes hand in hand with saving money and being good to the earth. The Water Watch brand is a new, clever way to keep track of your garden water consumption. Measure your water use in gallons. A built-in water meter (dial) lets you know how many gallons you have used so you can get a grasp of how much is required and how much you might possibly be wasting. The back of the sprayer has a built in spike for stationary irrigation. It's bright yellow so you always know where you put it too!"
