I agree with Kirk as far as the 'useful' info is concerened.
I have a Sage mechanical (thanks kirk) as the mechanical
backup to my SN10. I find that the Mechanical gives
me a good indication of whats happening outside with
air as it is compensated and gust filtered very well,
and the SN10 gives me a very fast response and allows
me to center quicker and stay there. In other words
when I hear an audio response to lift while cruising
I slow down and glance at the sage and determine whether
or not it is worth making a turn or moving on. The
Sage gives me a better avgerage of what I just flew
into than the SN10. The SN10 gives me a instant responce
that is to short of a time frame to tell if it is
a gust or continued lift. I would like to have a 9volt
audio back up connected to the sage in case of power
failure, but not enough room in the panel or is
there?

So the hole 'accuracy' argument is a bit ridiculous.
If it is really sensitive, it overreacts to gusts.
If it is highly damped, it's an averager. That's why
I want the audio, to let my brain (and butt) figure
out the gusts from the surges and center accordingly.
Tough while staring at a needle on a mechanical that
hasn't been looked at much before, after the needle
on the ubervario MK 69 falls off...
