Page 7 - Performance is king
It doesn't matter how many bells and whistles it has, or how stylish it is if a radar detector doesn't perform, it's not worth owning. Radar Roy
Many radar detectors are loaded with popular features, they look good on your dash and they are user friendly. Unfortunately, most of these units perform poorly at Ka-band and laser detection. Look closely at a detector's specification before your buy!
Before buying a radar detector, you must discover
False alerts: #1 complaint
A radar detector unable to distinguish errant signals will repeatedly produce annoying false alerts.
Many users of radar detectors complain about false alerts occurring when driving in urban areas. To appease these users, numerous companies have gone out of their way to limit their product's sensitivity in City Mode. Since most speed traps are confined to short-range catches, this is an acceptable compromise.
Ka-Band Sensitivity a must!
Stalker Radar (Applied Concepts Inc.) is now the largest radar gun maker in the world. They pioneered digital Ka radar guns in early 1991.
Today approximately 65% of all new radar guns sales are Ka band, 15% K band and 5% X band. As this is the most difficult band for radar detectors to detect, cheaper radar detectors (and even some more expensive models) do a poor job at detecting this band.
This is because X and K-band have a much narrower bandwidth (X band is a mere 50 megahertz wide and K band is only 200 MHz wide). At 2600 MHz wide, Ka band is 1200 times broader than X band!
This wider bandwidth requires a detector to spend valuable time scanning back and forth to detect. This results in lower sensitivity and less range before your detector delivers a warning.
The best radar detectors made today for Ka band is the Escort Passport 9500ix, the Bel RX65 and the Escort RedLine Radar Detector. Escort 9500ci cordless radar detector is the best cordless detector made today to detect this band. However because it is cordless, Ka range is less than the Escort 8500 X50 and the Bel RX65. (range will not improve even if you do plug in a cordless radar detector, as the circuit board is designed to operate on batteries)
You get what you pay for.
