New LXNAV V3 variometers in stock now

Can the mechanical needle of the V3 function without electrical input? So, if a total power loss, any vario function left? Thanks,

Hi,



There is a big hardware difference between the V7 and V3. The V7 has pitot

an static inputs and can therefore display push/pull (speed-up/slow-down)

commands. The V3 does not have pitot or static inputs. It can tell you how

fast to fly, but it doesn't know how fast you are flying, so it can't tell

you to speed-up/slow-down. The V3 is a great new idea. It is a Total

Energy vario with audio, with the ability to display the recommended

speed-to-fly based on your glider's polar and the current MacCready setting

and the current lift/sink. It is a lot like having a smart MacCready ring

on a mechanical vario. You can see details he
