[Update: Questions answered! It’s a motion-activated sprinkler, likely used to chase off any ducks or other unwanted visitors to the pool area. See the comments below! Thanks to all who responded to the post.]
What is it??
When the tide is high in the morning, we sometimes walk past a large house along the 7th fairway at the Waialae Golf Course. We have never seen the house occupied, but it is well cared for, the yard well maintained, etc. It features a pool along the golf course side.
And that’s where this question comes from.
There are a couple of tripods set up along the pool in different areas. At first I thought maybe they would occasionally hold an iPhone and take time-lapse photos of the pool area for security purposes, perhaps.
But today I took a couple of pictures so I could examine the gizmo a bit better. In the photo below, you can see that a hose is attached to the central part of the tripod. And then there’s a little controller of some kind attached.
The second photo shows a closeup of the controller box. It has buttons to change the “Duration” and “Range,” and a knob that can be set for Day, Night, Always, or Off.
So the question is, simply, what is this gizmo and what is it controlling?
