I got the pro in at noon today and have it out co-located with the fars and very early results look pretty good. I got a long way to go before things become clear. Today we had winds around 10 mph but did get a few short periods when the wind was calm and low at 1 to 4 mph and the new pro didn't miss a beat, temp stayed right with the fars, no spike due to low winds. Got to wait for one of the morning times when the sun is just coming up and no wind, that is the true test but just a quickie today and the fars max has been 62.3 and the pro 61.6.
