What is the Escort Redline XR?
Escort does not actually manufacturer a detector by the name of the Escort Redline XR.
The Escort Redline includes a feature that will enable you segment Ka-band, enabling you to turn off portions of the band that is not used by police.
The result is that a segmented Escort Redline will scan faster, with fewer false alerts.
Now the owner of retail website, RadarTest.com, decided that he could take advantage of the consumer to try to make an extra $100 off of each Escort Redline he sold by segmenting the Escort Redline himself (a simple procedure) and calling it the Redline XR.
Is the Redline the Best ever made?Well that depends. The Escort Redline is based on Escort’s M3 dual antenna design allows the Escort Redline to be specifically tuned for receiving all X, K, and Ka bands. It also contributes to making it undetectable to all RDDs including the
Spectre IV RDD. It is best suited for highway and rural use.
Because of its stealth nature of the Escort Redline, we consider the Escort Redline as the best if you live and/or frequently drive in Virginia where detectors are illegal, or if you’re a professional driver.
But, we also believe the Escort Redline is not well suited for driving in a city environment because of it’s reduced filtering capabilities and because it does not have an internal GPS or photo enforcement database.
So if you drive both in the city and on the highway a better choice would the either the
Escort Max 360 or the new
Escort iX.
Redline vs. Valentine One, which is better?In January of 2014 Car and Driver did a
review of the Escort Max and the Valentine One and here is what they had to say about the V1:
“
One annoyance is incessant false alarms—the Valentine’s filtering isn’t very effective. On our 22-mile loop, the V1 called out 53 threats in its most selective mode, which reduces but doesn’t eliminate X-band alerts. Turning off X-band is an involved process that you wouldn’t bother with on an interstate exit ramp. Determining what’s a cop and what’s not is left to the driver…”
Something else to consider is that the Valentine One is not stealth to the Spectre RDD, which is an important factor if you’re a professional driver and/or drive in the Commonwealth of Virginia.
