Update/Tip: The way our yard is this shoots too large of a swath so I went to Lowes and got a 3 foot piece of 1/2 inch aluminum pipe and made some new arms. I can now get as small as about 2 1/2 feet to around 40 feet. What's cool is that they can be adjusted or I can use combination of any of the arms. For instance, I will use one of the original with one of my new ones. The new one will get the center which the originals don't do that well. I drilled 1/16 inch holes which are plenty large enough. See my photos for a better idea.
