What are you backing up with S10? Don't you have mechanical vario?

No need for a mechanical backup the S10 has an internal backup battery for 3 hrs of use.

Never heard of anyone not having a mechanical vario in glider.

The two varios mentioned in the OP are all I have. The mechanical vario went away a long time ago, as did the mechanical compass.
