South Carolina
Spent quite awhile in field today(too wet to plant)
Got GPS speed on 2630 display- mechanical ground speed on corner display- radar speed on tablet for controller/monitor
Changed radar calibration number several times till GPS and radar matched-mechanical was always off a little due to slippage /tire diameter/etc.
Finally used 55 as the "magic" number- speeds were very close
Thanks
