I did some testing tonight with a K band radar gun, very unscientific. Pulled the trigger and estimated time to alert.
V1 was instant, no detectable delay.
9500i approximately 200 - 500 ms delay before alert in "A" mode. Maybe 100 ms delay in "H" mode. This was sitting still with GPS enabled, so "A" mode was at highest level of filtering.
As I said unscientific, but interesting.
My V1 3.861 also reacts instantly when a signal is detected. I wonder if the Escort would have problems if this was real instant on instead of a test?Quote:

GOL tested the 9500i against Ka POP. It scored 5/5. That test is more elucidating as to what the detector's performance is against quick burst signals. There's no way any IO can transmit a burst of less than 67msec, which is about what Ka POP is.
Can anybody explain why the 9500i --- in highway mode (which escort claims is the "always on" setting) -- has a latency?
Wouldn't it make sense if the 9500i is suppose to not be hampered by ANY features (ie: speed-features) in the "Highway mode", that it would perform the same as a VI ?
What I am missing here?
Thanks,
Well let's see. Perhaps the V1 alerts immediately to any signal that it happens to encounter. Perhaps the Escort units perform some anti-falsing tests to help cut down on alerting to other detectors or swept signal sources. Perhaps the V1 stops on the signal and completes its internal processing tasks without completing its signal sweep. Perhaps the 9500i, stops on the signal examines it, then completes it sweep to see if there could be a Ka as well before alerting on an X or K.Quote:

First I should say you can't assume the escort will miss a quick pulse completely..it may just be delaying its alert. Try triggering it quickly and releasing it just as quickly to see if you can find a speed that the V1 does alert to but the escort does not.
What bugs me is on the other end, escorts seem to "ramp down" for a few seconds after the signal disappears. The V1 will stop alerting just as instantly. It's not an issue as far as alerting you to radar, but it annoys the heck out of me, and I see it all the time on videos.
You have two schools of thought here. Escort wants to analyze the signal and make sure it is legit before it gives you an alert. The V1 alerts immediately and if it later determines the signal is not legit, it junks it afterwards. And that is the basis of a decision/recommendation between the two brands: do you want a detector that is as quiet as possible, or one that alerts as soon as possible.
Either way it would definitely SUCK to be hit with an IO burst and have no alert. IO is deadly as is detection wise anyway. If the detector (no matter what brand it is) cannot sniff out an instant on pulse, a trooper running it owns you.
I think you mean 500 feet.Quote:

K band only takes 100ms with the V1 and at least 500ms with the RX65. This is why you sometimes get those 1/8 strength falses with the V1 and you don't get them at all with the Belscorts.Quote:

These times were based upon 10 tries at each interval of 100ms from 100ms up thru 1 sec.
Bel RX65 I do not know the rev # but it was one of the early units L006503
K............did not work below 500ms. 500-700ms was mixed results. 700+ was 100% response
33.8.......60-100 was 100%. 120 to 500 0%. 500-750 was mixed. 750+ was 100%
34.7.......800ms
35.5.......800ms
Instant On is not a pulsed transmission. It is not likely that the radar operator will trigger the unit for less than 500msec, that's 1/2 second for the rest of us. It is likely the operator will trigger the unit for 1 to 2 seconds, perhaps longer.
As shown in the pulsed signal tests the V1 readily alerts to any bump in signal energy, regardless of the validity of the signal source.
To users that means of course that the V1 FALSES and falses and falses still more.
At the start of this thread Arkansas9500i stated that the 9500i ALERTED to the quick triggered testing. The unscientific guesstimate was 200 to 500msec in Auto while sitting still. The 9500i is designed to NOT detect X and K band when sitting still, unless the signal is so huge that it overcomes the "filter's" threshold setting. So, from the beginning this testing is simply bogus. It's a comparison of a heavily squelched unit to a unit that is running wide open. When tested in Highway, the 9500i according to this user alerted in "100msec". OK, so what does that mean?
The 9500i alerted in 1/10 of a second. Can anyone out there respond to an alert in 1/10 of a second? Can your brain decide what to do, can you get your foot off the gas pedal in 100msec? No and no and of course not.
Escort desgined this unit for the suburbs, mini-mall heaven, X and K band door radar sources by the dozens. Even the TV spot showed a typical male suburbanite driving a Minivan to a mini-mall.
Arkansas9500i's opening statements to this thread indicates that the 9500i design is in keeping with the targeted audience's needs.

This was the start of the thread. The 9500i has some delay with alert time but was better than my X50 when responding to quick trigger pulls. The 9500i has also the longest delayed alert of all the 3 - V1, X50 and 9500i.Quote:

Based on your test, when applied at longer distance, this is where the V1 has it's strength in picking up weak and quick trigger pulls and the 9500i may neglect the weak signal. You also have to take into account that the 9500i is better in picking up refelcted signals than the V1 at 90 degree approach and forward facing.
Bottom line, there is nothing you can do with instant on whether you have the V1,X50 or 9500i. But if you got a short alert at a distance, you can slow down. :wink:
I agree with this. LEOs are never going to "quick trigger" their radar gun just to avoid detection by radar detectors. If they are using Instant On, that is deadly enough and they most likely have you unless you picked up a signal ahead of time.Quote:

I agree. VR should change the programing to have a "window" with POP on and like Bel & Escort do, and no window with POP off. At least 500ms - not 100ms which just leads to more falses.Quote:
