"Instant-on" is just that - instantaneous - and FWIW, I fear I/O RADAR much more than I do LIDAR, which, despite popular perception, is not nearly as invulnerable, instantaneous, and precise as it may seem.
Our own community members have even tried to "out-brake" LIDAR (without any active or passive protective measures), versus outbraking RADAR, and in every attempted case, there's almost no escaping RADAR, whereas with LIDAR, there was at least some hope.
Indeed, as jaminc
said, the only defense for I/O RADAR is good driving practices - this includes the use of a proper "rabbit/bird-dog," as well as, when such are not available, to practice more defensive maneuvering, such as actively slowing before blind crests, corners, overpasses, etc.
No detector on the market today can help you avoid a ticket, via I/O RADAR, if you are the RADAR's specific target. Essentially, under such conditions, the detector can only alert you to the fact that you've been clocked.
While a more sensitive detector can potentially alert to the use of I/O RADAR, by the same enforcer, on *another* vehicle, perhaps way out of eyes' view (i.e. on a vehicle that was neither your own or that of your chosen "rabbit,") this is a scenario that is highly dependent on factors for which you cannot control. And given the fact that the 9500i and ix are already among the most sensitive of in-cabin, stand-alone detectors, it's rather unlikely that any other detector would've necessarily helped you avoid this ticket.
Furthermore, one should also remember that there are unique-detector -to- unique-detector differences - that "your" 9500ix may be more sensitive than "my" 9500ix and which may in-turn be more sensitive than "his" 9500ix, and that to complicate the matter even more, this performance margin can be limited to specific frequencies within each "band" (i.e. for the Ka-band, there's 35.5, 34.7, and 33.8 GHz). In one of Mike.B
's previous posts on RadarDetector.net, you'll see that of the three V1s submitted to him, there was a 3 dB difference in laboratory-measured sensitivity.
It's very, very hard to judge what detector is "the best."
Currently, nearly every detector carries a "fault" of some kind - an area in which its performance or features is not quite up-to-par to its peers. When one review or another makes the claim that product X or Y is "best," it's likely imposing some form of that particular author's biases and/or preferences in the overall criteria - and if your own preferences and needs do not match precisely such, you may not feel the same way, as the review or reviewer.
However, with *any* of the "top-dog" detectors, you can be virtually assured of "ticket saving" performance levels, in the real-world, given that your use of them is in a proper and realistic manner.
And I think that's where you tripped over the fault line, on this one, bkcttu
You're blaming the detector for what is essentially a scenario that it could not have helped you with - in a way, this ticket was the result of operator error, in that you did not use a "rabbit/bird-dog," as well as that you did not understand, fully, the implications of various tactical usage of RADAR.
You've mentioned in your post that you're new to the world of RADAR/LASER detectors, and I do sincerely feel bad for you that this was your "welcome" to this place.
Nevertheless, this is a valuable - if harsh - lesson: that your detector is not a "cop detector," and that there are various uses of RADAR which can defeat a detector, even one which is considered to be among the elite rank of the "top-dogs."
It is not my intent, by this post, to belittle you or to make you feel even worse than you do, now - but rather, to SINCERELY
hope to educate you on some of the finer points of detector usage as well as enforcement technology.
I truly hope your coming miles will be better.
BTW, this thread from my "home" Forum of LegacyGT.com should provide good reading for you. I know it's a long thread (7 pages), but the OP of that thread painted a near-identical picture as you did, above. I think that the replies posted there will give you some further insight into just what went wrong, in both your situations. ---> Pulled Over... - Subaru Legacy Forums
