Keep animals away from your pond or garden with a harmless blast of water.Protect your yard, fruit trees, vegetables, flowers and water features from hungry or destructive animal intruders. The ScareCrow motion-activated sprinkler automatically detects deer, raccoons, heron, dogs and more as they approach, and repels them with a short, but startling burst of water. The sudden noise, movement and spray scares animals away, teaching them to avoid the area in future.When it sees an intruder, the ScareCrow instantly sprays the trespasser with water under full garden hose pressure. The effect is both startling and immediate. Animals quickly get out of the area and avoid the area around the ScareCrow in the future. Eco-friendly and chemical free Uses 2-3 cups of water per deterrence Detects animals in a 1,000 square foot area day and night Easy to install, move and store A humane solution to unwanted intruders Runs for months and "fires" up to 5,000 times on one 9 volt battery Why It WorksThe ScareCrow motion activated sprinkler consistently creates a memorable and unpleasant experience through a combination of: Sudden, unexpected noise Unexpected movement Water spray The animal immediately associates this unpleasant experience with the location. To avoid similar surprises, they begin to avoid the area in which the ScareCrow resides. While humans flee several steps after activating a ScareCrow motion activated sprinkler, animals are scared to a much greater degree, run much further and stay away longer.We attribute this difference in part to the inherent fight or flight survival response found in most animals and their lack of intelligence or ability to "figure out" what caused the annoying noise and motion.Other reasons why the ScareCrow motion activated sprinkler works: Training/repelling is consistent at the location, 24 hours a day. It is the environment rather than a person or other animal doing the "conditioning". The water spray is sufficiently surprising and unpleasant to communicate an immediate "leave now" message. The ScareCrow protects any open area of the garden or yard that receives the unwanted attention of animals. The sprinkler directs water accurately up to 35 feet (8.5 meters) outward in an arc, protecting a 1000 sq. ft. (90 square meter) area. The sensor will easily sense large animals at a greater distance than the same sensitivity setting will sense a small animal like a cat. For example, set at a sensitivity rating of 8, the ScareCrow will "see" a deer at 35 feet (8.5 meters) but not a cat. At the same sensitivity, the cat would be seen at just 15 feet (4.6 meters).
