What’s the right choice for nozzle fan angle? 80 degrees or 110 degrees?
This question leads us to boom height. How do we select the right boom height?

Nozzle fan angle does play a role, but so does the type of sprayer you run and, more importantly, the height that creates the best overlap pattern. In this Spray Tips, Tom Wolf explains the drift risks and realities of boom height settings on high clearance sprayers, why high-set booms can negate the benefits of certain nozzle designs and why low-drift nozzles need 100% overlap. Then, it’s off to the white board to illustrate the relationship between nozzle spacing and ideal boom height.
