I wanted to start this thread by saying, that when you do installs on Blinder M25 and M45 units how important it is that the Heads are perfectly Level to the road. Today me and Jaykog tested a new Blinder M25 on his Mercedes benz. After I inspected his install which I thought looked very professionally installed, it ends up both heads were off center and not mounted level to the road. Our first run at 1098 feet coming up a hill I got instant punch-throughs with my Pro Laser II. I was hitting center Mass shots only. After putting the levels on one head, it showed the head was firing downward. So JayKog adjusted it and once we did a shot on a level road starting from 600 feet, I didn't get punch-through until about 116 feet. So I want anyone who is looking into purchasing a Blinder, to know that positioning and having the heads level to the road is so Very important. When the Blinder is installed correctly, it performs very well. I hope this information helps people who are looking to do the installs thereself.
