So I have these two units connected for the autoboom shutoff.   When you have to put in the measurements from the center of the sprayer to the start of boom 2 and 1....  Do you measure to the first nozzle of the boom or to where the nozzle sprays too?  I'm assuming to the nozzle since I run different types.  Will the work control have to be set on auto or on?  When changing the rate of application do you still use the raven?  Anything else I should be doing or watching for?
