The story of Chouka
As an engineer passionate about paragliding and mountains, I wanted to create a light, simple, and reliable variometer. It all started with a first hand-crafted prototype, placed inside a Tic Tac box and humorously nicknamed the “Vario Tictac”. After several improvements and test flights, this first prototype evolved into the Chouka variometer.
🇫🇷 Our products are carefully made in the French Alps, in Grenoble.

pas moyen d’obtenir une connexion avec XC track…
Bonjour,
Si après avoir suivi la procédure indiquée dans la notice vous n’arrivez pas à établir la connexion n’hésitez pas à nous contacter si vous avez besoin de support pour connecter le vario à XCTrack.

Marche très bien. Beaucoup plus rapide que le Vario barométrique intégré du téléphone Android ( je pense que XC contest ne marche pas sur iPhone). La batterie tient bien. Produit Français !! C’est tout bon. Du coup j’en ai offert un a mon fils qui commence le parapente…
per chi inizia come me è un buon ausilio soprattutto un ottimo rapporto qualità prezzo. Un suggerimento da parte mia è quello di mettere il cordino di un materiale resistente ma soprattutto che non resti attaccato al velcro, con il tempo si logora.

Testé sur trois vols et connecté xctrack à mon smartphone ça fait très bien le taff. Le plus serait une connexion bluetooth, mais je ne sais pas si c’est possible
The switch can be better.
