Hmmm no one has welcomed you yet, so let me be the first, fellow Canadian!

The best jammers out right now are the Antilaser Priority. After some research you should formulate your own conclusion but beware of the tests by people like Radar Roy. For unbiased results look at the recent test data by RALETC. I have personally been to one event and had my setup tested. It was a great experience and meeting people I talk to on here makes it that much more personal while discussing on the forum now.
