Dual-barometer pressure sensing
A dual-barometer design reduces pressure sensor noise by up to 31%, improving the quality of the data supplied to the sensor fusion algorithm.

High sensitivity
We will help you find the core of the thermal.
Duo provides real-time audio feedback based on gaining or losing altitude. Simultaneously broadcasting live flight data to the supported mobile applications. The audio tone curve is fully configurable, allowing pilots to customize its behavior.
How Duo helps in flight
Exceptional precision is achieved through the integration of leading sensors. A dual-barometer system detects the smallest changes in atmospheric pressure, while a high-performance IMU accurately measures vertical acceleration.
Combining data from all three sensors using advanced sensor fusion, FlySys Duo delivers highly accurate, real-time vertical speed information with exceptional responsiveness and stability.
FlySys Duo is powered by a dual-core microcontroller designed for deterministic performance. One core is dedicated exclusively to processing flight data, ensuring uninterrupted real-time operation, while the second core handles wireless communication, user interaction, and all other system tasks.
Live flight data is streamed wirelessly to the companion mobile application, which can generate climb and sink audio using the smartphone's speaker or connected Bluetooth audio devices.
The FlySys mobile and desktop applications make it easy to customize the audio tone curve, adjust device settings, and install firmware updates.
A fully charged FlySys Duo device provides up to 24 hours of continuous operation, enough for even the longest flying days. When using the smartphone to generate audio tones instead of the onboard speaker, battery life is doubled up to 48 hours.

Motion data helps Duo refine the vertical signal as the glider turns and accelerates.
Duo communicates changes in climb and sink through sound, so you can keep your attention on flying.
Connect Duo to the FlySys mobile app over Bluetooth to adjust settings before take-off.
