I installed Clear Nav vario prior to flying the 15-meter nationals at
Mifflin and found it to be excellent, much better than the 302 which
is right beside it. The unit is very capable on a technical level and
instant winds are in the feature set which will be a big improvement
over the L-NAV. It is good now but the real excitement for this vario
is in the future as various features are added through software
upgrades, including communicating with other devices compatible with
the CAI 302. The functionality of the audio is especially helpful. The
CN Vairo provides better gust filtering which cuts down on the false
indications of lift especially in cruise. During a rain day at
Mifflin I sat in on a management meeting for the Clear Nav group and
was impressed by their direction.
