The M19 is a great unit with audio/digital varriometer, damper,
averager,
a 2 scale digital altimeter (MSL & AGL), duration timer,themometer,
max climb/decent rates. I used one in a 1-26, L-13 and Pilatus.
Pilots flying racing sailplanes have different requirements from A
club user. Using it in conjunction with the typical non audio
compensated varios in these gliders was a real plus. The digital AGL
altimeter is nice for checking altitude early on tow. I'd recommend
it.

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.
