I have a Davis Vantage Pro2 which I installed two years ago. I am currently watching the console and the daily rain amount is steadily increasing and there is nothing but blue sky overhead.
from the beginning the unit has not lived up to expectation. The rainfall has never been correct compared to an old fashion plastic rain gauge and all efforts to calibrate the tipping cups has been unsuccessful. The anemometer has progressively deteriorated until it is completely useless. The only useful information it provides is temp., humidity and barometric pressure. In my opinion this unit is completely a waste of money.
The problems cannot be blamed on lack of maintenance as routine inspection of the unit is done on a regular basis and I am knowledgeable of the things that need attention.
I would never recommend this unit and will try to find something more dependable.
