Hey Mike, I see like 5 or 6 new Whistler XTR's at http://whistlergroup.com/newxtrs.asp all with the LED periscopes. Are they all based on the 690's platform, or not? What would be expected performance on these models?
EDIT: Reading the manual, the behavior sounds more like the 1793 style platform (i.e. VG-2 cloaking)
