Going to be going with my first guidance system on a combine next year. My options are the FM750 or FM1000, not going to be doing any yield mapping ect...... Just auto steering and cameras. Going to be running a 35' 1050 Maxflex Claas head with this setup what do you think of the level of accuracy you need with a combine? Is waas good enough for a combine? Or does a guy need to go to RTX, omnistar........ect....
