10 m/s vario? Really?

I thought euros used pretty much the same 10 knot varios the rest of us use, but labelled ±5 m/s.

Got to admit that I've no idea what EASA says of minumum equipment for cloud flying, if anything, but yes, that is at least what our (still valid) national regulation says. Nowhere is said that it has to be mechanical, though, so variable scale electric vario is ok. (I would not depart my beloved 10 m/s mechanical Bohli at any price.)
