QUESTION: How much more accurate is MeteoShield Pro over Davis FARS fan-ventilated screen?
ANSWER: The proof is in the pudding. On WXforum threads from year 2020 you can find independent testing of users who compared the naturally-ventilated 2020 version of MeteoShield Pro vs Davis fan-aspirated screen, also known as FARS by many hobby users. The results speak for themselves.
The difference was quite visible and striking. Without the use of fan-ventilation, the MeteoShield Pro was able to provide significantly more accurate air temperature readings than the Davis FARS screens during daytime hours in very low winds and strong sunshine.

IMPLICATIONS: The results of this testing show that the most accurate weather station currently on the market is the MeteoHelix IoT Pro which takes full advantage of the patented helical design of the MeteoShield Professional.
