John, what is the expected lifetime of VP2 anemometer bearings?

If I had to estimate, I'd suggest eg 5 years at an average inland/lowland
location. Coastal locations are typically going to be windier and have at
least some salt spray in the air. Actually the 6410 anemometer design was
revised some 2-3 years ago, in part with new lower-friction bearings (for
enhanced responsiveness at low wind speeds) and TBH there hasn't been enough
field experience with the new design to get a real idea of whether expected
longevity is any different. But I'd hope that at least 5 years was going to
be the benchmark again.
