m20 or m40?

[nitric]

Is there any difference besides the number of mounts between the m20 and m40? Im a little confused as to which to get.

This is going on a 06 nissan altima.

This would be great since im seeing more and more NJ state troopers with laser... I travel on route 78 from PA and there all over in western part of 78

not sure your question but i will try to help

The M20 has 2 jammer heads and the M40 has 4 jammer heads that the only difference, And with an 06 Altima you can get away with just an M20

Thanks....

My next question is... The jammer heads. In one video i saw the jammer heads light up when it was getting hit by laser. I assume this is the pulsations that the heads send back to the gun. So can the human eye see this light off the jammer heads?

Just trying to figure out how shealthy i can set this up.

No when the jammer is jamming it can not be seen by the human eye. They are light pulses being thrown back that you cannot see without the help of a special type of video camera. (cant think of it, night mode? im really tired...)
