Generally Mark - I agree.
You won't find too many contractors using
impact heads. We are all using
gear drives.
Both are "rotary", BTW.
The thing is....sometimes an impact head will go a little further in radius than a gear drive, so unless I know what the radius requirements are in Scott's application - I have to stop short of recommending a change over.
When I lay out a design with gear drive rotors...I like to space them anywhere between 22'-28' apart with "head to head" coverage so there's complete overlap. They are capable of going up to 30' but when you try to stretch them that far, you just don't get the best volume of water down, in my experience.
Of course...like anything theory is tested on a daily basis and every situation is different so these are just guidelines I like to go by.
