[AT] OT--foam marker for sprayers

[Greg Hass]

On my relatives sprayer, everything was in the middle of the sprayer; 
had 60 foot booms. Have not seen the ones on the ends; but then again 
have not seen a lot of things. hope you get it figured out. For 
spreading fertilizer I use a gps "sort of light bar". Its about twice as 
big as the ones you put on a car windshield but you set how far apart 
you wish the passes to be. Mine is a cheaper version at about $800. Not 
accurate enough for planting, but plenty good to spread fertilizer. I 
did spray with it once and did ok but it was fairly new and I was not 
used to it yet.
