#1188 of 1208 Laser alert on 9500i
Feb 27, 2008 (11:10 am)
I think i may be getting false laser signals on my new 9500i. It appears to go off for no reason. I have the unit mounted low,center windshield (my usual spot) My x50 never did this. In fact, I think the x50's laser alert was triggered twice by police laser and a bunch of times by my cd player but there was always a definite source. My 9500i has laser alerted me probably half a dozen times in the last couple of weeks w/ no obvious source. There weren't even any vehicles near enough to me to cause interference from a "cruise control" or "lane change" beam. Anyone else w/ this problem?

Although the problem isn't exactly common, it's not uncommon, either.
Currently, speculation for the cause of this problem runs anywhere from RF interference (unfortunately, no real solution on this one) to electrical noise (where a snap-on ferrite choke should help cut down on the problem) to "other" causes (various IR sources, or even the "flickering" of modern vehicle's nav/entertainment system displays).
With the 9500i, an e-friend of mine (whom I met through the Legacy enthusiast's Forums) was also having this problem - even the ferrite choke would not solve the issue.
He eventually elected to send the unit back to Escort to have this issue addressed - the technician reported that the solution was to "de-tune" (further shield) the unit's laser receiver - and would likely reduce the unit's laser sensitivity by upwards of 30%.

LT, this may be a question for you.
Are the radar units that the police have able to switch back and forth from say, K to Ka band? The vast majority of law inforcement in my area (town,city,county,state) use Ka band but every once in a while I'll get "K'd" by the county sheriff. Maybe they're using an older unit?

Unfortunately, this is beyond my shallow knowledge pool - my instinct, however, is to say no, that there are no "switchable band" devices.
Certainly, though, different departments will have different equipment, and this can even be *within* the department itself.
Local to me, for example, there are adjacent townships using K and Ka band, respectively, as well as one township which operates both K *and* Ka band.

I think my laser falses coincide with bursts of bright sunlight. Yesterday as I was driving around a long curve that was shaded, my laser alert went off as I hit a patch of bright sunlight. No other reason for it to go off. I wonder if I should send it back to Escort for a tune up?

^ That's certainly possible.
My ZR3's rear sensor is very sensitive to such falsing (particularly when sunlight is being "strobed" - i.e. driving on tree-lined secondary streets).
Although I have not yet had any sunlight-induced issues with my 9500i, I have heard of this happening.
[ Aside: this also happens on some other active laser-jammers, in addition to the Escort ZR3 mentioned above. ]
Would I send the unit back to Escort?
I honestly don't know - supposedly (coming from a good friend of mine, who sent his unit back to Escort for persistent laser falsing), their "fix" will decrease the laser sensitivity of this unit by up to 1/3.
Where this will place you, in terms of the absolute laser sensitivity of this unit (i.e. will it be as "bad" as a Rev.5 x50?), is still currently an unknown.
The good thing, though, is that you're almost guaranteed a fix.

Just wanted to be sure that you got notice to the reply.

Hey thanks for the reply LT,
So it seems I can either live with laser falses (which scare the crap out of me) or opt for decreased sensitivity. Now the other conundrum is that I must have been living w/ decreased sensitivity with my x50 all along.....or is the x50's adequate? Where is my philosophy professor when I need him?

LOL - Philosophy professor, indeed!
I think that when we bring up the comparison to our older x50s, we're not really going to be missing much, even if we got our 9500i's "fixed," if you will.
But does this mean that you are indeed compromising a lot of your protection?
It's hard to say, but I'm inclined to answer yes.
Still, having to live with persistent falses is a definite and BIG problem - it erodes the end-user's confidence in the detector, and causes desensitization, which can be a deadly problem even for advanced detector users.
There's a case on RD.net where a fellow detector enthusiast came forward and offered-up his tale of having disregarded his V1's warning, only to end with a ticket....
Particularly for a detector like the 9500i, where "the only alerts are the real ones," this is a big problem, IMveryHO.
#1197 of 1208 X50 age problem??
Apr 11, 2008 (4:07 am)
I have had two Escort X50 detectors. Both have started, constantly, displaying laser alerts. Laser is not particularly used around Columbia, SC. Both started after 1 to 20 years of use. The one I am using in my Towncar goes off every time I excelerate. Is this a normal problem? I am considering either sending them back for refurbish or just getting new ones. Which would be better? The 9500i is out of my price range at this time, but could be a near future option.
