Note that audio varios without TE compensation are almost useless. I
would suggest that you lobby the club to purchase several new or used
audio varios and properaly install them in your club ships. You might
prime the effort with a $135 donation to get the ball rolling. An
appeal to the group for used equipment might also yield good results.

A few of us low time club renters are considering buying audio variometers
to help keep our eyes outside the cockpit and our planes in lift.

One unit we're looking at is from Blue Sky Avionics, the M12 Cricket

There's also a fancier M19.

Does anyone have experience with these? Do they make sense to use?
Thanks.
