The on/off switch on the base eliminates trips to the spigot. With a coverage up to 5,800 sq. ft and a spray distance of 43', this sprinkler is ideal for large, mature lawns. With the easy-turn dial, you can precisely set the desired spray distance. The connection outlet is made to attach multiple sprinklers together for increased coverage. This product is backed by a limited lifetime warranty.
