This question was posted earlier but I was hoping for
a few more responses.

Do I put a mechanical vario or do I save space on the
panel.

Would love to hear what people have in their panel.

I think most people would agree that a backup vario is needed. They would
disagree whether the backup should be mechanical or electronic. I chose a
Borgelt B40 electronic vario as a backup since it has an internal backup
battery, audio and averager.

As to whether electronic or mechanical varios are more reliable, I have 4
varios in my "Cabinet of Ancient Instruments". Three are mechanical and one
is electronic. All still work except that the mechanical instruments all
indicate +1 Kt. due to the radium paint on the needles becoming lighter with
age.

Any technology can fail but happily, failures are very rare in today's
instruments.
