FAQ on The Scarecrow Sprinkler:
How long will the ScareCrow Sprayer operate before needing a new battery?Results vary from a few weeks to a year depending upon how often people, pets or the wind trigger the unit. The average seems to be between four and six months. The ScareCrow will typically fire approximately 3000 times from a single battery.
How much water pressure is needed?30 to 80 P.S.I. If your water pressure is greater than 80P.S.I., Contech recommends installing a pressure reducer (available at hardware and irrigation supply stores) at the hose bib.
Does the ScareCrow work at night?Yes. The ScareCrow works during the day and at night because it uses an infrared sensor.
Can I adjust the sensitivity of the ScareCrow?.Yes, you can adjust the sensitivity with the simple twist of a knob.
Can I switch the ScareCrow off?Yes. There are two ways to switch off the ScareCrow: either set the sensitivity knob to zero, or shut off the water supply.
Can the ScareCrow Sprayer be used in the winter?No. Bring it in when there is risk of freezing. Freezing water may damage the valve in the Scarecrow.
