Well, as we all know, the ZR4 is excellent at detecting laser. The laser detection modules inside the ZR4 front heads are rather compact as well and are only 1/4" tall, maybe 1" wide, and around 1-1/4" in depth. Years ago several RD manufacturers marketed laser-only detectors to compliment existing radar detectors with the advent of laser guns. I think that it would be really cool if Escort marketed a laser-only detector to compliment both Bel's and Escort's existing windshield mount radar detectors. Such a device should also feature a combination of a wedge and cylindrical case molded condenser lens which can "see" both ahead and also "see" laser scatter off of the front of your car's hood.
-- It should feature dual ZR4 laser detection modules for both front and rear detection.
-- It should be USB updatable for any new laser gun modulations which come out.
-- It should feature dual RJ-11 plugs and come with a mini RJ-11 cable so that it could be attached to the underside of existing Bel/Escort radar detectors so that it is powered by the existing RD power cord yet has the jumper cable to also power the RD.
-- It should be able to "talk" to the Bel or Escort radar detector in order to display laser alerts using the RD's display since it will not have its own built-in display.
-- Finally, it should measure no more than 2-1/2" wide, 4" long, and 1/2" in height, making it ideal for mounting underneath any Bel or Escort windshield mount radar detector.
The idea is to have significantly better-than-V1 laser detection capabilities, both front and rear.
