I'm thinking about getting a laser jammer. I already have an 8500 X50 so I was thinking about getting the ZR3 Shifter to go with it. However I know that it is already kinda old, should I just wait for something else? I hear that the M-40 is supposed to be a little better so should I shell out the extra 100 bucks to get better detection?
Since the shifter comes with 3 laser heads, two intended for the front and one for the rear, can I just put the rear laser head in the front of my car as well and have 3 laser heads there? I don't think I would ever need rear protection here in Mass.
