Performing speed run calibration – i50 Speed
This speed calibration involves carrying out up to 2 runs over a
measured distance, to enable a calibration factor to be determined
and applied to your unit. Each run consists of an outward and a
return leg, to minimize the effect of tidal drift when the calibration
factor is determined.
From the Intermediate calibration page:
Note: This procedure is not required if current speed is set to
SOG.
1. Press the Speed button until you reach the Calibration run
length page.
