How the Scarecrow Works
The Scarecrow protects any open area of the garden or yard that receives the
unwanted attention of animals. Its sprinkler directs water accurately up to 10
m (35 feet), protecting a 90 square meter (1000 sq. ft.) area. The Scarecrow can
see large animals farther away than it can small animals.
The Scarecrow uses a passive infrared sensor to see the temperature difference
between an animal and the background. However, if the animal and the
background are similar temperatures the Scarecrow will have difficulty
detecting movement.
When an animal or person moves into the field of
view, the Scarecrow notices the change and opens
an electronic valve to release a 3 second burst of
water through the sprinkler. The Scarecrow then
pauses for 8 seconds before resuming sensing. This pause creates an element
of randomness and unpredictability preventing animals from becoming used
to the device.
Sensing Area
The sensing area consists of several dozen alleyways through which an animal
must cross to be detected.
Animals like rabbits, cats and squirrels may cross under the sensor
alleys. The sensor will eventually see them. Larger animals and people
are seen the easiest.
The chart on page 4 shows suggested settings for various animals.
Sensitivity Auto Adjust
Nuisance or false triggering shortens battery life. When this happens the
Scarecrow will automatically reduce it’s sensitivity within five minutes
(except for a 1 hour period when the battery is first connected or sensor knob
is adjusted.) False activations are most noticeable during windy conditions.

The Scarecrow seems to have erratic sensitivity.
This could be due to the Scarecrow’s auto adjust circuit. Turn the sensitivity
knob to the OFF (0) position for two seconds. This resets the auto adjust
circuit. If this does not work, ensure the Scarecrow’s lens is clean by wiping it
with a soft damp cloth.
The Scarecrow does not ‘see’ animals.
Re-aim the Scarecrow. Refer to figure 2 on page 6 of this manual. If this does
not work, ensure the Scarecrow’s lens is clean by wiping it with a soft damp
cloth.
The Scarecrow only ‘spits’ water or makes a “pinging” sound..
This indicates the battery is low or your water pressure is too high. Replace the
battery or add a pressure reducer to the water supply.
The Scarecrow leaks water through its sprinkler.
Debris is lodged in its fittings. Remove the sprinkler head and stake. Backflush
water through the valve in the sensor head to dislodge the debris.
