In October 2003, Beltronics finally introduced their new RX Pro series radar Detector. And what radar detectors they are. 

The Bel RX65 is for customers who prefer a radar detector in the windshield.  The Bel RX75 is installed remotely under the bumper to hide it from observers.  A very informative and nice looking, Beltronics cockpit alert display with programming capabilities is installed in the driver's compartment.  Low noise falsing, very fast response time, high Ka and K sensitivity, detection of the new K and Ka Pop 3 radar, voice alerts, Bel product updates; there is too much to describe on the advantages of the RX Pro series, which are rated #1 around the world.

Escort 8500 X50 is is also a truly superb radar detector, also rated #1. Both the RX65 and 8500 X50 have a faster response than Valentine One and broader detection capabilities.  Escort 8500 and RX65/75 can detect to the front and rear, however, they do not indicate rear radar. Valentine One is slightly slower than Escort/RX65/75, but can detect and indicate front, rear and side radar.

RX65/75 and Escort 8500 can detect Pop 3 K band and Pop 3 Ka band radar (very fast radar burst). Valentine one can not. Neither Escort, Bel nor Valentine are 100% invisible to Spectre and Spectre II Radar Detector Detectors (RDD), however, they are 100% invisible to VG2 and MDS RDD.
