The new firmware for XC Tracer II is almost ready for release. The Sensor Data Fusion code was programmed from scratch. The result is a variometer that is even more precise than before, and in the same time the energy consumption even lower than before. If you are interested to test a beta version of this firmware drop me a mail at info@xctracer.com.

A wind estimation is also in the works. The screenshot shows data from a flight in Interlaken, the arrows show direction and wind velocity.
