Why not put an audible variometer in every glider?

There are also some clip-on audio varios from Flytec and Malletec that work great as well.

Towards the end of my training, I got a clip-on Flytec. I've found it hard to break the "look at the needle" habit. (My current plan is force myself to cover the dial when I'm thermaling.)

I'd suggest that audible variometers would best be introduced on day one of training, maybe even cover up the variometer dial until the student forms the habit of using the audio input.

I was lucky there - when I was learning all our club 2 seaters had audio
varios fitted. Of the simple audio varios I've used, I prefer the Borgelt
B.40 and the Tasmin V1000. The latter is preferable because it
continuously displays an average as well as the instantaneous reading.
Both have been around for a while so used examples can be found. Both
make pleasant noises. The B.40 is now superseded by the B.400 but the
Tasmin is still in production AFAIK. Both can accept a 9v battery as
backup: because of this I fly with a B.40 as backup to my SDI C4.
