Do ALL the current features work on the new vario?

Does the electronic total energy work? Are all filters(features)enabled for electronic TE?

Or does it require a TE probe for to to currently work and are all filters(features)enabled?

When all features are enabled(?)what is preferred... A TE probe or electronic TE?

Need a new vario and I am hearing great things about the CN Vario, so just asking.

Thanks, #711.
