After reading this thread one can conclude that quality of variometer signal is of secondary importance to most glider pilots. There doesn't seem to be many posters who really can comment on variometer quality. Colour displays, flashing lights and dozens of useless features rule... It's a shame really.















So, what is your definition of a quality variometer? A pellet vario will give you raw data, is that what you want? Come on, fess up, what gets you up best?

Ilec SN10B, Westerboer VW910, Themi. Mechanicals are just so 20th century...







I've flown Cambridge S-&L-NAV, WV910/920/921, VP-3,4 and 6, Zander SR-940&ZS-1, SDI C3, LX5000, LX7000, LX8000, LX160 (dozens-hundreds hours each) plus probably dozen other variometers for short flights.







So far the best electrical variometer has been good old Zander SR940 (yes better than ZS1), which I've used in 3 different gliders for over 500 hrs. Every other system is a league below SR, including all the new LX varios (both facctories), which is worrying since I believe they have majority of new computer market these days.



Hi

That's an opinion not a fact.

What makes the SR 940 the best?

Yes of course it is my opinion. And dozens of other european top pilots'. Go to worlds and look at their cockpits.

SR is only variometer that can show what is happening when you blaze trough thermal at 200kph. Others are usually all around place.

I'm not into old technology, I just wan't to point out that new technology isn't always better, as it should. I hope that Butterfly and Clearnav get the vario part right. Probably they need to mature few more years as nowadays nothing seems to work as advertised right out of the product line.
