Vario setup

Currently have a Winter Mechanical (never look at it) and a Borgelt
B40 (love it) with a Volkslogger (hate it) that I don't use into an
IPAQ/SeeYou that runs from a Keychain GPS (bluetooth and works great).
I'm looking to upgrade and simplify and am leaning to removing the
volkslogger, keeping the keychain GPS as a back-up, removing the
Winter and using the B40 as the back-up vario (I have a Lithium 9v
back-up battery installed on it) and getting a Borgelt B500 as an
upgraded vario/gps solution.

Love to hear comments from people with more experience than I in these
matters.

Thanks,

Brian

I love my B40 as a backup vario. I traded out my winter for it a few
years ago after having a power problem take out my main vario about
100 miles from home. After flying home with just the winter it traded
it for the B40 so that I would have an audio if that happened again. I
change out the 9V battery every year when I do the annual.

I installed the averager switch for the b40 so normally I just use it
as an averager but if my main vario fails and I can switch it over to
the vario mode.
