If you have ever gotten pulled over for going over the speed limit, then you know that it’s a hassle to deal with and get it taken care of. Not only that, but your insurance policy can also increase by a significant amount should you already have a prior citation. Fortunately, making use of radar detectors can help to prevent these occurrences and is simply a must have device if you drive frequently.

Before you go out to purchase the cheapest unit that you can find, you may want to consider spending the extra funds for a better quality one. Even if just one speeding ticket is averted, the radar detector will have already paid for itself and will continue to do for many years. This can easily results in savings of hundreds of dollars per year even if you speed by a small amount.

You want a detector that can read all the major bands that most law enforcement agencies use to detect your speed such as the X, K, Ka and Ku band. Most modern radar detectors these days are able to do so but there are still low quality devices that aren’t very effective. The Escort Passport 8500 even has a feature that makes it immune to detection so officers cannot detect its presence.

Another feature that you must have is for the detector to tell you which direction a potential threat is whether it is coming from the front or the rear. Valentine One detectors do a really good job at this as their units contain two antennas for extra sensitivity. These can even tell you whether a potential threat is to the sides of you which is beneficial for many reasons.

Another factor that you want to ensure is that the unit is user friendly as there are some models that can literally be working in less than 5 minutes. There are also some that do not require any adjusting as the settings automatically adjust depending on whether you are driving on the highway or city. Be sure to take these above factors into consideration when purchasing a unit for your car.
