Question 1

Will it work on mailmen delivering bills?

Accepted Answer

Shannon, yes it will work on things as large as humans, though we can't promise that they won't return with said bills at a later date.

Question 2

There seems to be an additional part in my package that is about 2" long and 1" high that is not part of assembly instructions. Any clue as to what this is?

Accepted Answer

The extra item drove me nuts for about 30 minutes. Until i figured out that it is simply a screw on replacement part so the "helmet head sensor" can be mounted by sliding the square part on the "valve square front. This lowers the "Helmet sensor" to be about eye level with like a rabbit or cat. 
Simply unscrew the all black small round knob that is on the "helmet sensor" remove the screw and remove the piece you just detached (the 4 inch bracket that has a round hole that would normally fit the vertical pipe shaft. Now replace that 4 inch part with the smaller 2 inch long part that has a square end and a round end. Push the screw thru the round end and into your "helmet sensor" (it only fits one way), then hook it/slide it onto the sensors square front. The "helmet sensor" now just sits there, not exactly a secured in a long term way but i guess it works.

Question 3

What happens if a human steps on the lawn?  Will that turn on and spray on a person?  I don't want it ends up spraying on myself 😂

Accepted Answer

Yes. It has happened to me also. If you walk on the side of Orbit without motion detector it will not turn on. It only detects movement of animal or human on front side of device. You can walk up to it and turn a dial to deactivate it temporarily.

Question 4

Thank you,

Accepted Answer

I have used this on my Koi pond for many years now with great success.  So I don't get sprayed during the day.... my water supply has a battery timer....   The timer is set for 10PM tp 8 AM..... so simple..... works great and I can set the time for it to work.
