I have the S3 as my 3rd vario, it is a great vario. But do consider getting the UPS battery pack sold as an accessary, provides 8 hours of operation with audio if you loss ship's batteries .

How do you use 3 varios? Are the audio's going on all of them? Which one do you
believe?

If is is very gusty I switch audio to the Butterfly and I believe the blue dot, for normal soaring it is V80 saved with 9070, and on those days when the clouds are lying, and I can't seem to believe the varios I turn up the volume on the S3 and that that has never failed to work when nothing else does. Plus it literally would not fail when everything else does as it has an independent battery or ship power. I do like 2G's panel but I up set mine up to work if I lose the main bus, get to airport without batteries... Steam gauge ASI, and ALT.
