We wrote a complete article on that subject, explaining how audio variometers work, and how to set up your audio profile according to your needs with the Vario Tone Editor, a vario simulator.
In order to be at your best when paragliding starts again, why not play with the Vario Tone Editor and set up your best audio profile and share it on our Facebook page ! (a simple screenshot with a little comment, easy !)
Everyone can use the Vario Tone Editor, even if you don’t have a leGPSBip+ ! It’s a simple web page, nothing to install 🙂
