The main distinguishing feature of the device Thermocompass from other devices that are used for paragliding, is that the device detects new thermals.
Thermals creates around the turbulent air from the friction of air flows. The diameter of the zone of turbulence is much larger than the thermals. When pilot flight crosses the turbulent region of the thermal, Thermocompass calculate the exact direction of the center of the thermals along the gradient amplitude and phase fluctuations of turbulence.
Finding effective distance depends on the strength of thermals and approximately 300 - 500 meters. When the TC detects fluctuations of turbulence of the thermal, it sounds like a variometer.
In addition, the device uses a maps indicating the locations where the thermals are born. So you can plan your flight is most likely to find thermals. These maps are calculated before the start with preFlightEditor and depending on weather conditions.
Device also has an effective thermal assistant, variometer on barometric, GPS and accelerometer sensors, and many other features.
