Thanks Craig.

I need to work on my description. Looking for Audio various.

Steve,
My backup vario in my current and my last glider has been a Westerboer with pressure sensors like these:

The one I have has a lovely tone - much nicer than Cambridge - and it indicates in absolute synchronicity with my Cambridge302. They both are on the same total energy probe. I prefer it when working really weak lift.
They sold for about $500.
