The Scarecrow’s passive infrared sensor stands guard at your water garden. When an animal intruder is “seen,” the Scarecrow releases a 3 second blast of water from your garden hose. The effect is both startling and immediate: animals quickly get out of the area and avoid it in the future. The Scarecrow motion activated sprinkler is sensitive enough to detect animals as small as rabbits and cats and will “fire” up to 1000 times on only one 9 volt battery (not included). This powerful, motion activated sprinkler will disperse 2 cups of water up to 35 feet away per deterrence, day or night.
