See the Invisible
The first affordable AR variometer for free-flight. See thermals in 3D space, track your flight path, and view instruments — all projected into your field of view.
Eyes Up. Hands Free.
Every instrument you need, visible without looking away. The first affordable AR variometer for soaring pilots.
AR Thermal Vision
See thermals projected into your field of view. 3D markers show exactly where lift is located, sized by strength. Your flight path trails behind you in real space. Turn your head — the display follows naturally, like real objects in the sky.
- 3D Thermal Markers — Up-arrows appear where thermals are. Larger arrows = stronger lift.
- Flight Path Trail — See your recent path in 3D. Visualize thermal circles and track your climb.
- True Head Tracking — Look around and markers move naturally. Pitch up to see thermals above.
- Full Instrumentation — Vario, TAS/GS, ASL/AGL, compass — all overlaid in your view.
Attitude-Aware Horizon
AR horizon line moves with your head pitch and tilts with roll, giving instant spatial orientation even in clouds or whiteout.
Instant Variometer
IMU-fused vertical speed with Kalman filter. Instant response from accelerometer, drift-corrected by barometer. Audio scales with lift.
Thermal Memory
Thermals you find are remembered and displayed in 3D space. Return to previous lift sources even after flying away.
Speed Display
GPS ground speed or true airspeed with optional pitot tube. Large, readable digits visible at a glance.
Auto Flight Logs
Recording starts automatically when flight is detected. IGC files with full GPS track, altitude, and timestamps.
Compass Header
Magnetometer-stabilized heading with no drift. Always-visible compass bar at the top of every screen.
Airspace Alerts
Visual and audio warnings when approaching restricted airspace. Download regional data via the companion app.
Stall Warning
Configurable low-speed alert with progressive warnings. Audio and visual cues before you reach critical airspeed.
Settings
Customize units, display brightness, audio alerts, and vario sensitivity. All adjustable on-device.
Madgwick filter fuses gyro, accelerometer, and magnetometer
FAI-compliant format for competition and analysis
Real-time data streaming and OTA firmware updates
All-day flying with USB-C charging
Accessories
Bluetooth Airspeed Sensor
Wireless pitot tube for true airspeed. Mounts on wing or riser, streams data via BLE.
Bluetooth Rotary Encoder
Wireless control knob for glove-friendly operation. Mount anywhere on harness or helmet.
Reflective Visor Prism
See-through optical upgrade. Display overlays your field of view without blocking vision.
Full Control From Your Phone
