V1 vs 9500i response time

**arkansas9500i** · 05-17-2007, 09:03 PM

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?

Instant On doesn't mean the signal burst is so short that a detector won't see it. With IO you have no pre-warning, so distance from LEO to target can be greatly reduced. At 500 yards, you're toast against IO. You're detector will certainly alert but as with a Laser hit, it can be too late.
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.
These detectors are far more sophisticated than most of us/you suspect.

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.

But the V1 does in fact alert sooner to K band alerts. This is also why the V1 is more chatty than the Escort.

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.

Valentine Research V1 Test 02/07/06
Rev 3.826

Factory Preset is POP ON
X -118 WOW
Ku -111 (default is OFF)
K -121 Responded 100% at time intervals above 100ms
33.8 -112 80% at 67ms, 100% from 100 to 200ms, 20 to 80% from 300ms to 600ms, 100% above 700ms
34.3 -115 0% below 500ms, 50% from 500 to 600ms, 100% above 700ms.

35.5 -113 0% below 300ms, 50% from 300 to 700ms, 100% above 800ms.
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.

I will be the first one to tell you that the 9500i is the quietest radar detector I have EVER owned even on H mode.
