WS-2300,2310 Owners

I finally got my replacement anemometer after 3 weeks, but I don’t think it’s quite right still. My wm918 show a wind run of 85.4 miles right now, the ws2310 shows 35.3. Tomorrow I’m building a tower to mount BOTH anemometers on, so I can compare what the reading are when they are mounted in the same spot.
