I did my own GOL testing today. Pulled up to stop light saw bmw to the right of me. It was a convert. he had his top down it was late evening so the heat finally came down to where you could roll down your windows and it was a nice night. But anyway upon looking I notice he had a V1 nice and straight right under his rear view mirror. I was actually shocked to see he had it in the exact place I put my xtr. I wasnt gonna drag race this guy or anything. But the light where sitting at is always long especially during the late evening. Anyway I get a ka band alert and about a second later. His starts chirping away. Just as mine said KA his alerted. The delay was like xtr KA - V1 Beep. It almost had a stereo effect to it. Anyway it was one bar. My whistler drop the signal and stop alerting his V1 was still chirping. Then my came back in with a ka again this time with 2 bars then finally both of are where ramping up and at this time the light turn green. Off in the distance was a LEO coming up to the light. We both went by the light I find it funny. The bmw slowed down and he look over into my car to see what detector I had.
I dont know what was all in play at that traffic light. But I did see the xtr alert first. I'm not saying the xtr is better then the v1 by any means. But it was a neat observation to say the least.
