I bought my first radar detector in 1985 and learned the hard way on how to use it. Instant on was a killer lesson and night driving another, but never made the same mistake twice. However, lasers are a different story. I have had a few very close calls and it is just a matter of time before I get a ticket from one. I am interested in getting a jammer and hope to learn here about the best way to use one from others who have experience with them instead of the hard way again!
