Basically a family friend has 2 v1's. One of them is a couple years old w/o the POP mode. And the other is a new one w/ the POP mode. I've borrowed both of them and amazingly prefer the older one. The new one falsed Laser from behind for about 20 miles on the GSP in NJ. Is there any way of looking at the actual unit to determine what version it is? I would like to see if I could find the same version as the old one my friend has on Ebay. Thanks alot.
