What Are Jam to Gun and Jam to Kill?

Having a radar detector and laser defense system in your car or truck is a great way to avoid speeding tickets. The success those systems have in helping you avoid tickets depends a great deal on how you use them. In this article, we’ll talk about laser defense systems and explain the Jam to Gun and Jam to Kill terms.

What Is a Laser Defense System?

Also called a laser or lidar jammer, laser shifter or laser countermeasure system, a laser defense system works to prevent a police officer from measuring the speed of your vehicle using a lidar (laser) gun. Because lidar guns can target vehicles very accurately (within a few feet at a range of 1,000 feet) and measure very quickly (often in less than 0.5 second), there’s no time for a driver to slow down once a detector has alerted him. Laser defense systems identify the light pulse pattern from the lidar gun, then transmit a signal that includes additional pulses that prevent the gun from working.

What Is Jam to Gun?

Imagine a scenario where you are driving at 90 mph in a 65-mph zone. When you are 1,000 feet away from the law enforcement officer, your laser defense system detects the lidar signal and starts jamming. In a scenario when you employ a Jam to Gun procedure, you allow the defense system to continue to transmit its signal and prevent the officer from taking a speed measurement.

In a Jam to Gun scenario, you never let the officer measure the speed of your vehicle.

The problem with the Jam to Gun method is that the officer will be expecting a measurement. When he or she doesn’t get it, they’ll know you are likely jamming the signal and may decide to pursue you in hopes of catching you speeding or doing something else wrong. You may have avoided the original ticket, but you may not get away without a fine.

What Is Jam to Kill?

A much better process is called Jam to Kill. When your laser defense system is triggered, you should slow down quickly but smoothly. You don’t want the nose of the car to dip suddenly, as that would attract attention. Once you’re at a speed that won’t attract attention, you can cancel the jamming signal transmission and allow the officer to take a reading. He or she may know what you’ve done, but without any proof that you were speeding, they will likely let you carry on your way.

When using a Jam to Kill process, you will cancel the jamming signal once you are traveling at an adequately legal speed.

React Quickly and Efficiently

If you are traveling at 90 mph, you are covering 132 feet per second. If the officer is 1,000 feet away, you have about 7.5 seconds before you are beside him. You need to respond quickly and efficiently to the laser alert from your defense system while not drawing attention to yourself. Several laser defense systems can be configured to automatically stop transmitting the jamming signal after a predetermined amount of time. Many users opt to set the system for 4 or 5 seconds. Others prefer to press a button to cancel the jamming signal once they know they are traveling at the desired speed.

For whatever method you choose, it’s worth practicing the process to the point that it becomes muscle memory. When the system triggers, check your rearview mirror, brake efficiently and smoothly, then cancel the jamming signal. Given that you’ll likely waste 0.25 to 0.5 second simply reacting to the signal, being good at completing the process is very important.

Protect Yourself with a Laser Defense System

If you find you occasionally (or frequently) exceed the posted speed limit, visit your local specialist mobile enhancement retailer and ask about having a custom-installed radar detector and laser defense system installed in your car or truck. Custom-installed radar detectors and laser defense solutions are something that you won’t want to try to install yourself as it typically requires the removal of the bumper covers and careful placement and alignment of the laser sensors for the system to function properly.
