Look at my side-by-side comparison of the Acu-Rite with the Davis VP2
http://www.lexingtonwx.com/comparison. I had intended to run the comparison for a month. The VP2 got so far off on Aug 2 & 3 that I had to recalibrate the Davis system. The Davis temperature data was no longer valid, so I ended the test. The Acu-Rite remains with no adjustment entered.
The Acu-Rite system was model 01010 with the 5-in-1 sensors, $99 from Walmart and the Davis VP2 retails for several times that. Looking at the data, you can't tell the difference except the 5-in-1 wind speed is much more sensitive. The 5-in-1 is now mounted on the same mast with the Davis Vantage Vue.
I have selected the Acu-Rite, which I'll now refer to as VN1TXC, to be the sensor package for the 1st version of the Wxtech Dream Machine.
