Searching for my first rate control system.  I have both CIH 500 and 750 EZ guide. Can I add EZ boom. And what components do I need. Might end up on both a 50 foot 3 section boom and a 12 row 30 planter.  Rate is primary.  Auto shut off down the road. What components would it take to add auto shut off? 

I'm sure info is somewhere in here. Search is running so slow, I'm not getting anywhere.
