Product Description

The FrSky High Precision Variometer measures the rate of change of altitude by detecting the change in air pressure (static pressure) as altitude changes.
When used with the FrSky Taranis transmitter you can create a true glider vario with tones that indicate lift and sink, a feature usually costing several hundred dollars for other radio systems.
