FYI:

When I first started with an Integra and GPS1600 receiver(WAAS) about 2014, and I did very good measurements on GPS receiver to axle centerline: axle C/L to drawbar hole; axle C/Lto 3 point balls; then the factory  "look aheads" defaults were basically perfect, right from the start. AND measure your planter's "attachment point" back to "seed drop area" and enter that into monitor also. (Mine was 13.25 ft; for an drawn JD7200 8 row planter)


IIRC: I think the "Look-aheads" were factory 1.0 and .3 ; over the years, I've only readjusted to .9 and .4 numbers.
