Yes it works fine for me. With my cab layout I am able to mount it close. The guidance lights are easy to see but the Screen might be hard to see if it were far away.
I use a App on my Ipad with a external GPS antennae from Garmin. For about $100 for antennae and the Farm Sprayer App I can get spraying and planting with a 12' End wheel Drill close enough to prevent missed areas & over spray. Keeps a straight line or follows the first pass
