I'm looking for a Digital Average Display (DAD) for a Borgelt B40 Vario.. New or used. Only 300 hours on the instrument.



Ermm ... why?



You can fit a simple two-way switch to go between average and instantaneous display on the needle (see manual, but it's a 5 minute job). I use my B40 on average pretty much all the time, using the audio for instantaneous readings. Works really well, and if that needle is even a hair above 0 then you're climbing.

That is an excellent idea. Should I feel the need to stare at the panel, I have a secondary mechanical vario that reads "instantaneous".

Someone offered me a new DAD for $150, but that seems a little high. I like your solution better.
