I have a ZR3 that was linked to my x50's, but now that I upgraded to the V1 I obviously run it as a standalone. Anyhow, now that I upgraded detectors, I am thinking about doing the same for my laser jammer. I looked at the GOL tests, in the laser jammer fourms, and at the Radar Roy test. It just seems that all of the jammers have some compromising flaw. Also, are any of them upgradeable like the V1? If I keep my ZR3 installed and get another system, could I run them simultaniously? Basicly, whats the best protection I can get?
