What does DC do exactly? What I am looking into is an AL Insight to do section control for planter(CaseIH 955 with SLECTRO controls) and section control for a SP sprayer(Rogator). I have found a few widely varying ways to go about this. 1 Insight has dc boxes and no autoswath. 2 Insight has autoswath and no DC box but is running an liq app module and tapped into boom switches for section control. Which works best, and which is the best way to go for my situation? ? ? ?

Thanks.
