The biggest problem for any gardener is how to keep animals away from your yard in the kindest way possible. To pull that off, a automatic system that repels animals without chemicals or traps is required. Contench, Havahart and Orbit all make these kinds of yard sentry systems that offer garden protection in a humane way.
How does a automated water sentinel work? A motion activated sprinkler sprays water for a couple of seconds when its sensors detect any movement in the area. Animals get startled by the sudden movement and burst of water and over time, they will associate your garden and orchards with insecurity, and ultimately avoid visiting at all.
The Contech Cro101 scarecrow sprinkler has a lightweight plastic shaft and a metal sprinkler head. The 17-inch unit has a mount, sprinkler, and motion detector. The scarecrow sprinkler can cover up to 1000 square feet of the yard. A group of Contech Cro101 units can be connected together for bigger spaces. The battery-operated scarecrow sprinkler runs with a 9-volt battery. You’ll also need a garden hose connected to the sprinkler unit for it to function. For maintenance and repairs, Contech Cro101 is covered by a 2-year warranty.
If you check for reviews, most users have given Contech Cro101 a 5-star review. It effectively gives stray animals just the right scare, without putting their lives at risk. There are also notable reviews about this scarecrow sprinkler that don’t only focus on keeping stray animals away from the yard. Some people like this because it keeps the grass in the yard hydrated too, especially because it covers 1000 square feet.
The Contech Cro101 has a motion-sensor, it can detect any movement including humans. So when someone attempts to enter your yard without warning, he or she is going to get drenched. Don’t make the mistake of crossing the yard in your date clothes though when the scarecrow sprinkler is activated.
However, it can work as a burglar detector too. Since Contech Cro101 can detect any motion, it will spray water on the intruder and strip off his or her defenses. Most likely, the intruder will be caught off guard and make noises.
