Whistler Radar Detector Features

The Whistler XTR-438 is one of the best radars on the market. It is absolutely packed with functionality and features. One of the best features about this model is the 360 Maxx coverage that it offers.

This means that it doesn’t have any blind spots and can detect radars in any direction. This is important to have because having a detector that just picks up on what is in front of it is hardly ideal and leaves you open to radar detection on all sides. 

The next feature is the battery saver. This detector is specially designed to save battery and power so that you can get more hours out of your radar.

Having a radar that doesn’t work due to low battery is extremely frustrating and not ideal. Another well-known radar with this feature is the Uniden LRD450 Laser Radar Detector

Finally, the last intriguing feature that we want to talk about in this section is the setting saver abilities of this radar. While some other radars annoyingly make you reset all of your preferences in between uses, this radar saves them each time so that you don’t have to go through the process again. This definitely saves time and frustration and is a great feature.

Great Radar Detection

Though we talked a little about the detection that this radar detector offers in the previous Features, it’s an important topic that we need to expand on a little bit.

The design of this radar allows for 360 degree protection from radar. That means that if a radar is located behind you, then you will still be able to detect them.

Some other radars don’t have this feature and won’t alert you if the radar isn’t right in front of you. Another area where this radar shines is in the quality of the detection system. 

This radar features G-2 detection, which is the best in anti-radar protection and keeps things discrete. If you’re looking for a truly quality experience in your radar detection, this model is a great affordable option. 

High Grain Lens

The high grain lens on the front of the radar makes it easy for you to read the feedback that it puts out. With no dead zones, this radar gives you constant feedback and is easy to read from your seat. You won’t have to strain your eyes to read what it is telling you or become a distracted driver by leaning forward to read it. 

You also don’t have to worry about operating the buttons. They are large, easy to read, and easy to use. Simply press them to adjust settings or modify signals and you are well on your way to a fully-customized radar detection service. 

Safety Warning Systems

One thing that you’ll hear about frequently when shopping for a radar detector is how many false positives it does or does not give off. This radar is fairly effective and affordable, but it does have its downsides. You may notice a fair amount of false positives when you are using this radar because it can be set off from the safety systems of other cars. 

This is one inconvenience of the machine, but that doesn’t mean the value is not good. This is one of the more affordable radar detectors out there and if you are looking for one on a budget, it will serve you just fine and get the job done. You might have to deal with some false positives, but they are well worth it for each time you can avoid getting a ticket. 


You might recognize this product from its early days as a Best Buy radar detector, but it has since blossomed into one of the most effective and consistent radar detectors on the market. The Whistler radar detector is a fantastic budget buy for anyone looking for a radar detector who doesn’t want to spend hundreds and just needs something simple.

Just because it’s affordable, though, doesn’t mean that it’s not effective. This product is used by thousands of people daily and has tons of features that make it a very appealing option for almost anyone. The dozens of features, affordability, and ease of use put this detector above similar ones in the same price range. We are confident that you won’t regret buying this radar detector by Whistler.
