Can a 2600 or 2630 be used for both guidance and a yield monitor in a 70 series combine w/o unlocks? No real need to print maps. How accurate are the yield monitors on the 70 series combines if calibrated correctly? I hear issues with the moisture sensor. Is it really that bad? We have been using a agleader insight, but thinking about trading combines. Will I be disappointed with Deere? Don't really want two displays in cab. Thanks.
