What are the differences in the inertial nagivation systems between the Butterfly vario and the S80?



The LX literature was confusing on how wind calculations are made and it says in one place that the S80 makes continuous wind calculations on its own but in another place it says that the S80 requires the compass module to improve wind calculations.

Where did you see that a compass module can be connected to a S80? I did not see that in the manual.

S80
Inertial platform 3 axis digital +-8g accelerometer, 3 gyroscopes (for inertial vario, AHRS and wind calculation)

The question about the difference between the butterfly and the S80 is probably proprietary information for both companies.
