I have been flying with the S80 as a stand alone vario. It is connected to my Oudie/SeeYou and Flarm brick.

My unit is set-up with 100% electronic compensation. I have a Winter vario connected to the TE probe.

I have been flying with the S80 using the default settings/filters and it has been very good. It responds a bit faster than the Winters and seems to be less "jumpy" in turbulant conditions with horizontal gusts. My previous electronic vario was a Cambridge 302 which was very satisfactory.
