FYI
I am on my fourth temperature / humidity sensor for my 12 year old Vantage Pro2. I just replaced the last sensor, it only lasted 22 months, the sensor part number was Davis Part #6930. Davis has replaced the sensor with part # 7346.070.
The new sensor is supposed to have tighter temperature tolerances and will work with any Vantage Pro2 built from 2006 on. Each time the sensors failed it was always on the Dew Point side. Hopefully the new sensors will have a longer life cycle.
The biggest hassle is taking apart the fan aspirated radiation shield to replace.
A two to three year life cycle is not good, the product should be more robust.
I do not live near a salt water environment so that's not a concern, I live in New York State so it gets cold in the Winter.
Keeping my fingers crossed.
