Butterfly vario side-by-side with ClearNav vario

The advent of varios with inertial probes that enable the compensation or identification of horizontal gusts will be especially useful in hot strongly thermic areas, like Arizona where I mostly fly.

This is especially true on days when the air is stable but still rises strongly because of very strong surface heating. Thermals in these conditions often have a strong horizontal outflow that increases the energy of the ship as you approach the thermal. Since your total energy increases, all conventional varios indicate lift, leading the pilot to turn too soon. Many experienced pilots know this and compensate as best they can, but it would be great to have a reliable vario do this for you.
