Never ever buy a cobra radar detector
Aren't the jammers illegal?
Radar jammers are illegal in almost all or maybe even all states laser jammers are only illegal in a few states
Is it just me or are more cops catching people with timing and not using radar detectors that often?
IME K band is ALWAYS false alarm. KA band is most of the times accurate. Though I never get alerts for laser. What type of code is used for laser?
K a band is used on old radar guns, that's why you don't really see it. In ny/nj the cops all shoot ka and the ones that are shooting laser bought their own expensive equipment.
I've seen k in nj
Just join hatzolah. Have a friend who for sure saved money due to his lack of getting tickets.(As a side point I also almost missed shabbos (would have still been driving) but we pretended to give an escort to an officer and drove right thru all the traffic, and got a thank you wave from hime whem we sped past the accident)
from a cop?
Yes. Never on a highway but I saw it in Lakewood and in colts neck (on my way to court for a speeding ticket)
I sometimes see it on those permanent signs that show you your speed, but never from an actual cop. I guess lakewood uses some old equipment. Though many of them definitely shoot KA.
