Orbit Yard Enforcer Motion Sensor Impact Sprinkler. It provides motion activated watering to protect your plants and garden from animals. The heat and motion-activated sensor detects movement from up to 40 feet away and triggers the valve to spray a burst of water. Easily adjusted for sensitivity and range, the sturdy zinc spike provides easy positioning and an additional outlet for attaching multiple sprinklers. This dual-purpose sprinkler also features a timed watering function that allows you to water your garden for 30 minutes at a time. Keep deer away from vegetable gardens, cats out of flowerbeds, birds from strawberry patches and ponds, and dogs away from lawns without the use of harmful methods.
