The SPX 7800BT is an unparalleled performing detector almost half the size of other detectors in the global marketplace. It is quick as lightning with its transistor deflective driver sweep circuitry that provides you with further detection ranges. You will be alerted in advance to all radar and laser guns presently being used in the U.S. and Canada. This includes POP radar detection that police use to defeat radar detectors. It detects Instant-on Radar guns as well. The colored OLED display offers relevant information for signal detection and the current operating method of the detector.

Detection Bands

A great feature is the 15-band detection that is very impressive when you consider the U.S. radar guns operate with three radar frequency bands.  Those are the K-band, X-band, and Ka-band that represents three signal types:  radar, laser, and safety systems.  Within these three signal types, the unit detects seven radar signals, six brands of LIDAR laser guns, and two safety system signals.  This does not appear to be any different from typical radar guns except for the added Ku-band and three RDDs (radar detector detectors).  The inclusion of three RDD indicators does not add value other than to claim 15 bands of detection.  It is legal to own radar detectors in the U.S. by passenger vehicles but not allowed for commercial vehicles—unless you travel through Washington, DC, U.S. military bases, Virginia, and a few other states.  There’s no need for concern about the RDD use by law enforcement.

Here in the U.S. only the X-band, K-band or Ka-band is allowed to operate.  That is the reason most radar detectors disregard the Ku-band.  If the U.S. uses the Ku-band in the future, Cobra’s SPX 7800BT radar detector puts you ahead of its competition.  Cobra thinks the Ku-band will be used in the U.S., since it is used in Europe, but infrequently.

Alerts and Mapping

Because the SPX 7800BT is well matched with Cobra iRadar free app you are in for many alerts.  The noteworthy straightforward mapping characteristics benefit the community using this functionality; it’s ahead of its time.  As an award winner launching community resources such as detection abilities, and threat sharing with the most recent Cobra iRadar App Version 4.0, it’s the best.  The unit provides for powerful driver tools from inside the iRadar app.  More of the road ahead is shown with the new rotating map merged with an automatic zoom feature that centers upon the speed of a vehicle.  For improving your driving knowledge, it permits users to see alert sites ahead of time before actually getting to them.  To view alert areas, you can now tilt, rotate, and pan the map easily.

You will benefit from more mapping and navigation operations using the new Live Traffic Data.  This indicates real-time traffic on the map so you can circumvent all the traffic congestion.  The Get Directions allows you to enter an address and the best route will be plotted using iRadar.  This functionality can be supplemental or replace the need for a separate app to navigate your path.  You will know the long isolated stretches of road and spot alert areas on the Coverage Map View.  You will be alerted when you zoom out as to where iRadar warnings are.

Threat Sharing and Pairing Advantages
