That's a pretty neat sprayer, M5. I made an attachment to my spray rig once and mounted a boomless spray head. I had so much drift that I had to take it off. Wind was almost nothing when I tried it but still the chemical drifted well beyond the spray width. How does yours do with drift?
Drift is usually caused by pressure not matched to nozzle size--or vice versa. Pressure too high causes fine atomization to the point of a mist which = drift in even the slightest breeze. Most nozzles have an operating range---to get larger droplet size (less drift) use the lower end of the reccomended pressure range.
My 35 gal sprayer uses Boominator type nozzles--I do not care for the sizes I have at all. They do a good job, but in order to get an acceptable swath width, pressure has to be run up so high that they tend to produce a mist. 15' wide is about the best I can do with it and not get drift. They come in different configurations, but here's a simple 180° fan shape.
Boominator:
On my 300 gal sprayer, I have 2 nozzle setups, controlled by a rotary valve that allows me to choose which nozzle set I want to use, as well as any combination of nozzles and a circulating bypass to mix with.
I have this boomjet cluster nozzle, but since this picture was taken, I added a little short 4' long Fimco setup, that is located below and forward of the boomjet cluster.
The Fimco I use if I don't need a real wide swath or if I want to shut off one side or another (each of the 3 nozzles has an intergal shtuoff valve)
Boomjet spraying (not my picture) --you can see that it is producing an output that will be large droplet sizes:
I run it right at 30-35psi while actually spraying. This is the 3rd year I've used this setup--and am pretty happy with how it works--I'd be a lot happier if it weren't so far travel back to the well to refill when I'm done with a tankfull. I do also wish I had bit the bullet and just bought a lower profile cylinder shaped 250-300 gal tank. Climbing up on that trailer to mix chems up on top of that tote is getting wearisome on this old man.
