Hi Paul,

I have the ws2300. I'm not sure what the difference between the ws2300
and ws3500 is, but I can tell you the ws2300 is reasonably accurate but
is let down by a poor 'propeller' design anemometer - you should bear
this in mind if the ws3500 has the same design anemometer.

It appears as if the WS3500 doesn't have an anemometer, but the 3502
does.

That's not a problem though, since I have nowhere to site an anemometer
anyway.
