When looking for radar guns for speed law enforcement, you want one which motorists’ detectors cannot locate with ease. A leading online store for high-quality speed guns and related equipment advises that it is vital to know how these detectors work. Being savvy on matters on speed guns functional efficiency is also key.

Speed Guns: Their Functional Principle

First off, these speed guns come with the technology for emitting radio waves which bounce off the target to tell how fast cars are moving. The guns follow the Doppler shift theorem, which depends on the principle of the alteration in wave patterns. With this, you can tell whether cars are moving toward detection points. You can also record the speed and how far away you are from the car. However, you will need first to ascertain what specific car in the speed gun cone is of interest.

Why Zero in On One Target?

You only can get a clear reading from your speed gun when the gun emits a high and constant tone. You will get a weak signal if it reflects from a low or raspy target. You want precise readings from your target car, and it is best if you can get the car’s license plate, headlight or bumper as these easily reflect the waves. Vehicles which move very fast reflect best from the speed gun cone on the ‘fastest’ button.

Application of Speed Guns

Practically, you can control speed guns from your hand or mount them on your dashboard. For officers on bikes, lighter speed guns are the best to use. You can customize your order for these lighter speed guns but specify the exact size. Also, specify the battery type and size as these handheld speed guns will not have an external source of power. Most of the speed guns, however, come with both on- and off-charge capabilities. It is not just enough to know how speed guns work; it is crucial you understand the various modes available. These include:

Moving Speed Guns

When an officer is in motion, the speed gun compares the officer’s and other car’s speed. The speed gun calculates by looking for a background object which is large. It then focuses on a target object which is smaller in size. Next, it measures differences between target speeds and of the police car, the latter of which you can get from your speedometer.

Directional Speed Guns

Moving speed guns have had the challenge of the shadowing errors when you assume the large vehicles to be the stationary object. This technique leads to errors in speed calculation for a target vehicle. Directional speed guns are quite accurate. The patrol car’s speed is not a major factor here; results should be from the signal bouncing off the target vehicle.

A leading online store for radar guns and equipment posits that these calculations should be highly accurate. You cannot get that from old technology where the officer has to pick out which target car to bounce off the signal. Therefore, whenever you are shopping for your speed guns, insist on getting those that come with the latest technology.
