I was doing some last minute testing today.. was getting JTG/JFG results aside from a small number of sub 50ft punch throughs (due to small weaknesses that i'm fixing), and all of a sudden I started getting a ton of PT on my tests. At first I thought it was a bad jammer head since I couldn't get it to go off even in parking mode. So as I keep testing my friend tells me that the jammer light/buzzer wasnt going off (red light/sound). We come to find out the sun was killing the jammer head sensors! I have videos which I'll put up either tonight or tomorrow, but basically if your driving towards the sun before sunset, the sun will not allow the jammer heads to detect LIDAR hits (interference?). This is a rather serious flaw since your basically left without protection. If your driving away from the sun and towards LIDAR then the system jams fine, but if your driving towards the sun and get hit with LIDAR the system will not detect it, therefore it will not jam. Also, if you put the system in parking mode, you can actually make the sensors go off with the sun. I do have my heads in a chrome grill, so I'm not sure if that's doing some weird reflection, but I'm not sure I'll be able to test with a blacked out grill since I have to return my laser tomorrow. Heads up Blinder!!
