RE: True wind on eS128
Welcome to the Raymarine Forum Chris,

Within performance sailing, True Wind data (sometimes called True Relative to Boat—is Apparent adjusted for Speed Through Water and Heading) requires speed through water data. Please click here to view a FAQ addressing this subject. As the Airmar PB150 does not feature a speed through water sensor, it would not be capable of calculating the through water vector and would thereby actually be reporting wind speed with respect the vessel's motion over ground ... this is not True Wind per the definition specified above. Should you supply a sample of the complete NMEA 0183 sentence transmitted by the Airmar weather station, I will backfeed it into both a C90W and an eS-Series MFD to see how each responds.
