many Scarecrows should I use to protect my valuable koi?

birds, fence in your Koi. We cannot accept responsibility for losses.
might cause my unit to act erratically when I am setting up?
A: Onboard computerized sensitivity dampening kicks in after
the unit has been ON for 5 minutes. Turn your unit off for 2 seconds
to 'reset'. During setup you may wish to 'reset' every 5 minutes
to avoid this 'erratic' behavior.
does the Sensitivity and Automatic Sensitivity Adjustment circuit
A: When a new battery is installed or if the sensitivity
knob is adjusted, the sensitivity of the Scarecrow is set according
to the numbers shown on the knob. This value of sensitivity will
persist for 1 hour (unless the knob is adjusted which restarts the
1 hour timer). After this hour is up, any 4 targets/activations
in a 5 minute period will turn the sensitivity down one half level.
this could happen as fast as every 40 seconds if the triggers
are immediate, one after another. This process continues until
less than 4 targets in any 5 minute period detected.
the unit will never go to sensitivity = 0 which is OFF.
If the sensitivity
has been turned down automatically, every 15 minutes the code
will check to see if there have been any targets in the last 5
minutes. If there were any, the gain is left at its current level.
If there were none, the gain is adjusted up one level.
If a target
occurs within 4.5 seconds of an automatic turn up, the sensitivity
is immediately turned down (and the solenoid will not fire). If
the sensitivity knob is adjusted at any time, the sensitivity
will be reset to the new knob setting and the one hour fixed sensitivity
period starts again.
causes my Scarecrow to trigger when there is no animal or person
A: Wind usually. Branches, flowers or leaves can move and
be 'seen'. The Scarecrow itself can also move in light wind.
Moving water is also a cause of triggers. Avoid pointing the Scarecrow
towards waterfalls. See Troubleshooting
for more on this.

you can approach it from behind.
the Scarecrow be used in the winter?
A: No. Bring it in when there is risk of freezing.
is my unit 'spitting' instead of spraying in 3 second bursts?
A: This is the low battery indicator. Change the battery.
If the problem persists, contact the company for assistance.
type of hose should be used with the Scarecrow?
A: Use the highest quality consumer hoses. Cheap hoses will
can I reduce the risk of flooding my back yard if I'm leaving a
pressurized hose on all the time?
A: Don't leave the tap open all the way. Experiment with
leaving open 1/4 or or 1/2 turn. The longer and more pliable your
hose, the less open your tap needs to be as the hose will act as
a pressure reservoir for the 2-3 cups needed.
not sure I like the 'garish' look of the Scarecrow. Can I get it
A: Yes. It comes that way by default. Applying the decals
for the beak and eyes is optional at your discretion.
I hook it up to my inground irrigation system?
I replace the plastic sprinkler with a brass sprinkler?
A: Yes and No. Technically it's no problem. However, in practice
the high quality impact sprinklers tend to move more SLOWLY and
SILENTLY. This make brass sprinklers less effective at doing the
job of scaring animals.
the Optional Mounting Bracket for?
A: For installing up off the ground, ie: on post, building,
tree etc., or on a board for ground level use. Note: hand tools
required for this type installation.
