Real wind information is available (Butterfly Vario, Clearnav etc) and I

think it is valuable but it comes with a multi thousand Euro price tag so

upgrading my "old" (and perhaps not very reliable) technology is not an

option.

I haven't looked at Butterfly pricing, but the Clearnav vario (with instant

accurate wind and nav to home base) is only multi thousand Euro if the

multiplication factor is less than one. And (by user reports) is the best

vario on the market bar none.

' And (by user reports) is the best vario on the market bar none.'

That seems like a long stretch. Do you work for them?

The latest generation varios from Clearnav, LX, and Butterfly seem pretty comparable as a vario, the Butterfly has many more features than the others beyond the vario (and a price that reflects the features). I have not experienced how the others perform, but the Butterfly provides instantaneous wind (and I mean "instantaneous") and seems quite accurate.

No, I don't work for them. But I do sell them, and all the other varios by
major manufacturers. I haven't met the same level of enthusiasm for
anything else. The difference seems to be that experienced pilots 'know'
what the air is doing, and a vario enhances that information. The ClearNav
vario seems to agree more closely with what a good pilot feels, and makes
centring and maximising climb more efficient. Likewise the instantaneous
wind appears highly accurate - a useful feature particularly flying in
mountains.

I was sufficiently convinced by the feedback that I bought one for my
glider with my own money, and agree with what my customers say.

Hi
It is unfortunate that the Flight Computer display is one large size only. A 70%screen,like the picture in the Soaring magazine advertisement, would fit my LS6panel. Any other option?

Yea, get a glider with a bigger panel

Seriously, I flew this year with both the CN vario and the LX climb vario (V3) and the sound matches quite well between the two and so does the needle (only climb tested). Very rarely you hear something out of tune. So after flying many hours with both I can say they are pretty close but the LX Vario sounds much more pleasant to the ear. I bet the LX Navigation Vario is the same. It is good we all have difference preferences or life would be very boring.

As a simple climb vario - given that the manufacturers are all using functionally identical barometric sensors and that the filtering algorithms are pretty well understood - it would be a surprise if a particular one was "the best bar none". Now, I can't claim to be a pilot with enough experience to "know" what the air is doing (with only 44 years soaring and 30,000 cross country miles I still require a variometer to quickly center a thermal). It would be interesting to see a video of all three brands in the same panel flying through a few bumpy thermals to prove their differences, if there are any. In my mind the differences are more in UI and extended features.

I thought the CV vario used GPS and air data to calculate wind?
