I found these Sprinkler Gauge a few years ago and they are perfect for finding out exactly how much your sprinklers put out for a given time. I have used them to calibrate and adjust all my heads so they are all putting out the same rate of water. Knowing all of that also comes in handy if you have a Rachio as you can put that info into the controller. for $1.50 each, it's almost hard not to purchase a few of them to use. I may buy more in the future so I can do more heads at once. It is really an eye opener to see how much water actually gets put down each time.
