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.
