Finally a way to keep unwanted animals out of the garden and protect your yard, fruit trees, vegetables and flowers from hungry or destructive creatures. Cats, dogs, deer, rabbits, large birds, and many others. The patented Scarecrow motion-activated sprinkler is the smartest scarecrow ever invented. When it sees an intruder it instantly releases full garden hose water pressure towards the trespasser. 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 constructed of durable, high-quality materials, and has been designed to provide many years of reliable service.

How does it work?
The ScareCrow uses a combination of sudden noise, unexpected movement, and a startling blast of water to create a memorable and unpleasant experience for the trespasser.
The animal immediately associates this unpleasant experience with the location, and to avoid similar surprises, learns to avoid the area. If an animal chooses to return, the ScareCrow will be waiting.
While a human may flee several steps after activating a ScareCrow, animals are typically affected to a much greater degree. In most cases they run much farther, and stay away longer. Because the unit only triggers when the animal moves, its behavior is difficult for animals to anticipate, making it a very effective deterrent.

Rating : - Excellent scarecrow sensor works!
We were having a difficult time keeping rabbits off our lawn. One had returned yet again to start another nest, after I had cautiously relocated her bunnies from her last litter to another area. I was concerned as I did not want to cause any harm to her offspring. Once this product was installed, it was able to detect the slightest motion in its path, and a stream of water would scare it off. We have not seen any more rabbits on the lawn since this was installed, however we did water down a guy sent to do some lawn work at our request!! NOTE: If the scarecrow is set at its most sensitive, a strong breeze or wind will also set it off.
