I had some time as I was going to get lunch to test out the K band capabilities of the whistler vs. the K band of the V1. There is one store along a long straight road that has K band radar, so i used that. I drove up to it twice with each detector, running only one at a time. The whistler was in highway mode, x off, pop off, kamaxid
The Valentine started picking it up at about .3-.4 miles away on both occasions. Came on as 2 dot alert at first, and worked up to 4-5 dots.
The runs with the whistler went like this. I got to about 150 yards before the K band alert came on, both times. In each instance it only beeped once and then stopped, then beeped again as i got closer.
Just thought i would pass on my experiences.
