  • Which Radar Detector is the Best?

    Which radar detector is the best is a simple question but the answer is not so simple. You see what might be the best radar detector for one person might not be the best for another and I will try to explain how to choose the best one for your needs.

    If your needs are for a custom installed radar detector than that answer is easy because there is only one unit available today that fits the bill which is the Beltronics Sti-R Plus.

    Its the only custom installed radar detector on the market today which utilities Escort & Beltronics M3 platform which in my opinion is the best platform available to date. Its a dual antenna which is completely immune to RDD's (Radar Detector Detectors) so if you travel through areas where radar detectors are banned they can not detect you have a radar detector on.

    It's also the only custom installed radar detector which utilizes KA Band Segmentation so you can remove segments of the KA Band that are not used for real police radar which enables it to scan through the frequencies much quicker. Along with KA Segmentation its can also allow you to turn off RDR (Radar Detector Rejection) which normally can delay the detector up to 1/2 second while the detector tries to determine if the alert is a false from a near by leaky radar detector. In an I/O (Instant On) situation this 1/2 second delay could cause the detector to miss one of these quick radar shots.

    For Windshield Mounted Radar Detectors there are 3 of the top radar detectors:

    Here are our choices for the top 3 windshield mounted radar detectors.

    1. Escort Passport Max ($549.95)
    2. Escort Redline ($499.95)
    3. Valentine 1 ($399.95)


    The Escort Passport Max we rate as the best city use radar detector and while it had a rough start with several firmware updates under its belt many original issues have been corrected. The biggest gripe many have with this radar detector is Escorts marketing claims which claimed it was the best radar detector with the maximum range of any other radar detector.

    The Escort Max is not the longest range radar detector ever made but it is close to the performance of the Escort Redline which we will discuss later. It is however the most sensitive gps enabled radar detector and does replace the Escort 9500ix as the leader in this category.

    For city drivers the use of a radar detector can be a huge annoyance because there are many false alerts that you will encounter. The most common false will be from automatic door openers that share the same frequency of police radar. While these sensors are not looking for speed they are using radar to sense motion and trigger their doors to open when people are walking into the stores.

    Sensitive detectors like the Escort Redline or Valentine One will constantly go off because they are so sensitive that they can many times detect these sensors several hundred feet away. I can tell you that running a non gps detector down a main city road with many drug stores or supermarkets the false alerts are almost non stop, Its almost desensitizing that when I see a real threat I can tend to ignore it because I am used to the false alerts in the city.

    The Passport Max has an auto learn function that keeps track of your driving and notes every alert it detects in its internal database. AutoLearn technology uses the power of GPS and the exact frequency of the false alert and automatically will reject unwanted door openers and other fixed position false alerts on future passes making it extremely quiet in the city.

    If you are looking for the best radar detector to use mostly in the city and you can afford it, The passport max is the best detector for your money.

    The Escort Redline is a great detector and there is no doubt about that. If you are a highway driver this unit is awesome and it is the most sensitive windshield mounted radar detector built to date. Its built on the solid M3 antenna platform which is a dual antenna that offers the best off-axis protection available. I have received alerts around hills and curves with no issues with the Redline.

    In areas where detectors are not allowed such as Virginia, Washington DC and parts of Canada this detector has been the favorite. Its the only detector in the Top 3 that is undetectable by police RDD's (Radar Detector Detectors) which are devices used to sniff out vehicles using radar detectors in banned areas, If you live in one of these areas and want a radar detector this is the detector to get hands down.

    I have seen many videos from customers of ours (See Escort Redline Detailed Review) on the Best Radar Detector's website for videos that will show the Escort Redline detecting threats as far away as 10 miles. This is a crazy sensitive detector and for Highway use this detector is simply the best.

    The latest firmware update on the Escort Redline with enhanced RDR/BS options enables you to now have advanced Band Segmentation ability which was once only available on the much higher priced custom installed Beltronics Sti-R Plus. BS (Band Segmentation) allows users to select certain frequency ranges within the KA band to turn on or off. Removing certain bands from the scan that you know are not used in real police radar allows the Redline to scan the KA Band much faster.

    RDR (Radar Detector Rejection) option with the new Expert Firmware was not an option you could turn off in previous editions. This option allows the detectors to eliminate False alerts caused from nearby radar detectors in other vehicles. While this works great to eliminate false alerts it causes the detector to pause (Only for Miliseconds) while it determines if the alert is a false or a real threat. The problem is I/O and POP Radar are very fast and having this option on could cause the Redline to not alert to one of these real threats.

    Using RDR & BS at the same time almost turbo charges the response time of the Redline (See Escort RDR/BS Video) while not adding many additional false alerts. Since you eliminate segments of the non real police frequencies you can eliminate many of these false alerts and you can use the RDR Off function to dramatically increase the response time of the detector. These are not features the average user should play with without guidance of knowing what is used in their area. We can help with setting up your Redline properly in your area.

    So to sum it up if you are a highway driver or live in an area where radar detectors are banned the Escort Redline is the best overall highway performing radar detector.


    There could not be a top 3 without it the Valentine One. For many years the Valentine was the leader of the industry and was considered by enthusiasts the best radar detector around. Times have changed and Valentine has let the Redline pass it as the most sensitive detector. Though not far behind the Redline it is still priced cheaper and is still a great value at $399.95.

    The Valentine 1 is a highway radar detector like the Escort Redline. It does not have the stealth capability that the Redline has so if you are in a Virginia, Washington DC or parts of Canada where detectors are banned this is not the detector for you.

    What is does have that makes it special is two separate antenna's (One in the Front and one in the Rear) so the valentine can help pin point the direction where the signal is stronger to give you an idea where the signal is coming from. The Valentine is the only detector with a front and rear antenna which can help alert you to the direction of the threat.
