The smaller the better if you know that you want to avoid your speed being checked. Because both the Radar and Laser devices work by firing energy (they do these in the form of microwaves or light) at your car to tell the speed, the bigger the target the larger the bounce back will be.
So, a big target like a truck can be speed checked from up to a mile away, actually, it can be detected beyond the field of vision of a human being. So, if you are a truck driver, you may be speed checked by a cop you cannot even see.
A smaller target like a sports car has to be much closer, like about 500 feet maximum distance.
The first thing that we will tell you before we let you know what product we can advise you to choose, seeing as our selection will not be tailored to everyone’s needs. There is not such thing as a one size fit all product in the world, and the list we curated in our guide article shows that.
The guide we have was made in the hopes that there will be something there for everyone, and one that matches their own specific requirements. So, if the price of the product is key to you, there are radar detectors from the full price range of less than $50 to ones that can be bought at over $500 and everything in between.
There are detectors for both Laser and Radar, and some that specialize in Radar only (many police forces do not make use of laser speed guns).
So, you should take a look at some of the key features as discussed in our previous articles. You should decide which ones are key to you, and you should make sure to check our products guide. Maybe this time, you might find a product that you skimmed past which could turn out to be one that you need.
