Doggman,
I have several types of spray booms, BUT, all of them after purchasing, I install a plastic valve in the line that goes to each nozzle, that will cut the flow off what nozzle not wanted to spray. That being said, we can spray any way or any direction wanted. If I just want to spray a fence line or a small enbankment, I will turn off one side and the middle, and let just one side spray. There are different combinations that you can spray. Left only, right only, middle only, right & middle, left & middle, left & right only , etc .. etc... >>>>>
Another thing that can be done, is if you are just wanting to spray one side, but not to far out, either change nozzles, or , you can barely close the valve to shut down the pressure on that nozzle, resulting in a spray, but not shooting as far out.
Fimco also makes several different size nozzles . Some nozzles spray more GPM than others, some spray mist, some jet, some of them fan..... Most of there nozzles are color coded. Give them folks a call and tell them what you are lookin' for as far as the type of fluid spray you want, and they will be glad to help on the perfect nozzle.
