Valentine Research (
http://www.valentine1.com) has an in-depth article on this new type of 'pulse' radar. (Called POP mode by radar manufacturer MPH Industries.) I will not attempt to rewrite the article, but instead relay two points that the article makes:
1. POP mode is inaccurate; the electronics in the radar gun are unable to initialize quickly enough to get an accurate reading.
2. Because of this, it is stated in the MPH Industries' BEE III Operation and Service Manual, "A note of caution: Information derived during the POP burst is non-evidential. Citations should not be issued based soley on information derived from the POP burst."
Thus, while it is possible to be nailed with one of these, the officer behind the radar gun would be unable to issue a ticket based upon any reading derived while in POP mode.
There are other radar guns out there that disperse their beam less, but the Valentine One is quite capable of picking up this radar, even when the beam is narrow. I took my Valentine One to a friend's workplace, where they sell and install all of the equipment on the city police vehicles, including radar guns. He brought out all of the models available and we set up a series of tests. Even pointed away from the vehicle, the Valentine One picked up the radar at significant range. (Even laser, which surprised even myself.) He was very impressed with the radar detector, as were several police officers that were there at the same time. Many had heard of the Valentine One, but very few have actually seen it in action and were skeptical of its performance. I'm not sure if I made the officers nervous or not.
Regardless, while I do not speed often, the times that I have, the Valentine One has located radar far in advance of the radar gun coming within a usable range of my vehicle.
