Rocky Mountain Phazer II Radar Laser Detector Review
Rocky Mountain Phazer II Radar Laser Jammer
Rocky Mountain’s Phazer II offers what seems to be incredible: a device that can prevent your car from being picked up by speed detection devices for the price of a low-end radar detector. Is this too good to be true? 
Yes.
Radar detection works by detecting the Doppler Effect when bouncing a radio wave off the side of the car. The Phazer’s radar jamming is passive: when struck by a radar wave, the Phazer II sends a differing radar pulse to confuse the radar gun. In a best-case scenario, if the device works, it can hide itself from the radar, but not the car. It’s like building a stealth fighter, and only making a couple of the bolts radar-absorbing. The only effective device for jamming radar is an active system, which constantly sends out radar pulses to confuse speed guns.
Laser detection is difficult for even the best devices, as the limited range of laser devices means that they can’t be picked up unless very close to the source: by the time you get a warning, the policeman is probably in sight. Buyers may be attracted to the Phazer II’s laser jamming system, but like all other systems, it is completely ineffective for much the same reason as the radar jammer: the counter-laser would have to hit the laser gun to give a false reading.
If the Phazer II can’t deliver on either laser or radar jamming, is there a reason to buy it? Perhaps. Buyers of the Phazer are covered by Rocky Mountain’s ticket rebate program: for one year the company will reimburse owners for any tickets within 15mph or 30% over the speed limit, whichever is lowest.
The Phazer II retails for $130, but can be found on the Internet for as little as $100, for what is essentially a plastic box that cannot live up to the promises of radar or laser jamming. What you’re really buying is a form of ticket insurance.
