Contech CRO101 Scarecrow Review

This is the main sprinkler I used to almost completely rid my front and back yard from the neighbor’s feral cats. This brand and model is very easy to set up. It requires one 9-volt batter to work and detect motion.Once the battery is inserted, you connect the garden hose to the base of the sprinkler. One battery lasted my almost 3 months, with sprinklers shooting 10-20 times or more each day (see explanation below). When a batter starts to run out, you’ll notice that the detection is not as good and the spray distance is not as far.

A little muddy from winter rains and 3 months of use, but still works like a champ

Make sure the cap is secure on the other end because there is a second port that you can connect a hose to in case you want to chain several sprinklers together. The downside to this is that if both sprinklers go off (which can happen easily if they spray in a similar direction, ie triggering each other) you will get less of a spray distance due to lack of water pressure.

Originally, I purchased 4 units, each for $50 a piece, but now this model seems to be unavailable on Amazon for that. My new #1 recommendation is the Orbit 6100 Yard Enforcer because it is a similar design to the Contech, but also comes with day/night sensors and is made of higher quality material.

I was quite happy with the results I got from the Contech Scarecrow. The only frustration for me was that I could not get a proper angle in my front yard to deal with all the non-cat movement. If I place it facing the neighbors yard, it would go off when they got home. If I place it facing the street, it would get triggered by cars driving by. Reducing the sensitivity helped these situations, but then they wouldn’t go off when cats strolled by.

It took quite a bit of tweaking to find a happy medium, but was possible with two connected units.

    I recently purchased one to stop my dog from pooping in my garden. But haven’t been able to get it to work! I connected the hose from my garden tap where the water pressure is about 0.8 bar, to the Scarecrow water sprinkler. As soon as I turn on the tap, water is shooting out from the connection point on the sprinkler! Do I need a special adaptor for my garden tap to allow water flow only when the sprinkler is activated?
