I got to looking at my setup and the head closest to the headlight is angled about 10 degrees toward the center of the truck. I found this by using a green laser pointer that has a visible beam at night. When I mounted the pointer to the side of the jammer head it was very evident this head was pointed toward the passenger side of the truck.
After you fix the head and level it, maybe if you have time we could do a more controlled test with the Laser Veil and Blinder M45 again. Let me know and I can get a good mount for the tri-pod and retest with the Pro Laser III and Truspeed. Just let me know what time and day is good for you.
