Just hook it up to your garden hose, plug in the battery and point it over the area to be protected. It's that easy. Scarecrow senses animals the same way security lights detect people; movement and heat. When an animal is seen, a valve opens instantly releasing a three-second pulsating spray of water. The combination of the sudden noise, movement, and water frightens animals away. This startling, yet harmless action is a remarkably effective deterrent. A 9-volt battery and a hookup to a garden hose is all you need to operate your ScareCrow. Battery life is measured in the THOUSANDs of ?activations?. As a rule, the baterry should easily last through an average summer's use. Up to 1000 square feet can be covered by one Scarecrow. A 35 foot deep and 45 foot wide 100 degree sensor detection zone provides plenty of garden protection. If you've tried other solutions that failed, you're ready for the Scarecrow. 2 YEAR LIMITED WARRANTY! 30-DAY MONEY BACK GUARANTEE!
