I do not have a mechanical vario. I have a computer with vario, a Butterfly and I have a LX V3 with battery backup, which I think is much better than a mechanical vario. I usually just leave the V3 off, but if I lose my main bus, I still have an electric vario with audio good for 8 hours of flight time. The V3 can be run off main power or battery backup. This V3 vario has it's own speaker so it is a compact install. I believe a few other manufacturers off the same type of functionality.
