Today I got video of the Pro 78 going against a K Band Speed Sign. Alert was about 2 miles. The second time I went against it with a camera I U-turned to early and didnt get the initial alert I did with the first pass, if that makes any sense. On video I got 1.75 miles. More like 2.0 mi with the first pass. Freeway was full of traffic and it has low and high spots. If anyone knows where I can upload a 178 mb video let me know so I can show it.
