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.

I don't.

I also do not have a mechanical vario...No need (at least for me) at all....In fact I am somewhat amazed folks are still buying them. Perhaps some clubs still buy them for simplicity or for some other reason, but I haven't had one in many years...
