Ultrasonic 6400 May 28, 2018
Reviewer: joseph vidulich from PORT CHARLOTTE, FL United States  
The Ultrasonic purchase went smoothly.
The product performs exceptionally during dry conditions but has been very disappointing during rain events making the data unusable.
The problem is the device generates erroneous spikes in the wind speed during and after a rain event. The spikes show wind speeds over 100 mph when the winds are actually calm right after a rain. I am contacting the manufacturer for guidance.
