Yes! The CircleScout suite of products was designed with circles in mind, but that doesn't mean that we can't get almost the same amount of information from a lateral irrigation system.
There are some options with laterals; how you would like them to appear on the map will influence where you a) install the CircleScout satellite monitor and b) set your Centerpoint (see article).
Here are some examples of how a lateral will appear in the CircleScout app (available on for iOS, Android, and via web at app.netirrigate.net)
