The Scarecrow protects your garden with a super high sensitivity motion sensor that works both night and day. When your Scarecrow detects an intruder, even as small as a rabbit, it immediately unleashes a powerful three-second blast of water from your garden hose. Those unwanted pests get the message right away! The Scarecrow is humane, environmentally friendly and startlingly effective. Effective up to 10 metres and uses only 2 cups of water per deterrence.
