Radar detector manufacturers are constantly playing a game of catch-up with new technologies designed to nab the lead-footed, some of the critical factors when buying a Radar Detector are :
False Alarms : The case when too many false alarms occur. If your Radar Detector constantly falses than you’ll start to ignore it eventually – and then in a case of a real radar trap it will be too late.
x/k Radar Sensitivity : These frequencies have been used already in the 60 and 70, therefore the radar detectors manufacturers already know how to detect them from miles.
KA Radar Sensitivity : More expensive components are required for this type of frequency, most manufacturers prefer not to include this feature to save money on the development of the device.
Gatso Sensitivity: usually used in Speed Cameras, this the most widely used worldwide frequency – only very good K-Band sensitivity will help you here…
“Pop” Radar Technology : A relatively new instant-on technology that may make a whole generation of radar detectors obsolete. These radar guns operate at low frequency until they are switched on to determine a driver’s speed with lightning-fast accuracy. This leaves a radar detector little opportunity to scan and detect the radar signal.
Pop radar may sound ominous, but a new crop of radar detectors offer Pop radar detection. Sometimes Pop detection is not enabled by default in the radar detector, however; users must turn it on in the settings menu.
