In our opinion, there is no such thing as a “radar jammer”. Not one that works, at least, except maybe for a classified US Airforce project and we can’t tell you about that…. because it’s classified.
Laser jammers and radar detectors are often referred to radar jammers but they’re totally different things.
Laser jammers are illegal in New Zealand, although you may be interested in our laser parking systems.
Radar jammers, while advertised overseas, simply do not work. In fact industry guru Radar Roy is so confident they don’t work, he’s put a $50,000 reward up for one that DOES work. He reckons it’s a safe bet, and so do we.
Do NOT buy anything advertised as a radar jammer, it simply will not work.
