It's been now over 8 years since I changed to an all electric panel.
My primary vario is a Cambridge 302 and I have a Westerboer pressure
sensor vario (no flask) as a secondary. With two batteries that can
each run the panel for many hours I had so far no problem. I cannot
see one reason why a mechanical vario would still be needed. The
Westerboer is completely in sync with the Cambridge and of course has
an audio output that I actually like much better than the one on the
Cambridge.

Go and throw out the Winter, you can probably sell it for the price of
an electric.

I am considering dropping a Winter Vario from my panel . I have a Glide
computer and primary electric vario on board as well, as an Ilec
electric. Just trying to lose some weight from the cockpit.
Any PRO's or CONS's I need to know about regarding reliability and
redundancy in flight......batteries in the cold etc??
Cheers
