difference b/w POP and instant on
What is difference between POP mode and instant on? At the bottom of this site http://www.radartest.com/article.asp?articleid=9090 it says that BelRX65 is better with POP mode but X50 is better with instant on. I coulda sworn they were the same darn thing.
Pop is a very short burst in the order of a few ms depending on the gun, it does not last the whole time the LEO pulls the trigger.
This burst is not detected by most detectors. Instant on lasts the whole time the leo pulls the trigger, so perhaps a few seconds.

Okay, read the referenced thread (thank you), but still have n00b'ish questions.
If it's just you and the LEO on the road, it appears that getting instant on alert is like getting LIDAR alert (without a jammer) -- that is to say, a ticket notification. First question: is that a fair assessment?
(the GOL FAQ pretty much indicates this, but perhaps I missed soething....)
Likewise, the gist of everything I've read indicates instant on is quite reliable, and POP isn't even useful for issuing a citation. Second question: why on earth would any law enforcement organization bother with POP? If POP is detectable and not useful (in and of itself) for issuing a citation, it seems that there should be no market for it...
Third question: Are all [modern] radar guns instant on capable?
In answer to your first question only, if you're the only one on the road you won't have any indication of 'instant on' because nobody else will be getting shot with it. So yes, it very well might just mean 'here's your ticket.'Originally Posted by unixium
No radar detector of any type is going to provide you a warning if there is nothing at all to detect before you get hit with radar. A detector of any sort is only one tool; the other one equally important is using common sense. Never drive fast on a "deserted" road, or at least be aware that doing so is risky.
POP was *originally* intened to make RD's obsolete (of the time), because the radar detectors (of the time) were not able to detect POP... so an LEO could be as casual as they wanted with 'POP' to get an estimated speed on a target (without alerting any RD's becuase it was simply to short of a burst for the detectors-of the time- to detect).
Then if it (a POP displayed speed) was close enough to what they would pull over (IE 67 in a 55), the LEO could just hold the trigger for another 1/2 second (depending on model) and then BOOM instant-on hit... which unlike POP does obtain accurate readings that (often) hold up in court. So it was a brilliant idea except 2 flaws:
Expensive units
Rd's soon were able to detect (67ms) POP.
(16ms is the new trend which no detector can effectively and usefully alert to)... but again expensive units.
How much more expensive are they?
Ahhhh, POP is a pre-cursor to instant-on. That make sense. Thank you AirMoore.and then BOOM instant-on hit...
Understood hoosier...Never drive fast on a "deserted" road, or at least be aware that doing so is risky.
So the moral of the story: keep rapid driving confined to congested roads where one can maximize their damage potential. :wink:
Sorry to dig this topic up again, but the damnable questions keep popping into my head.
Why isn't instant-on considered inaccurate like POP?
In both cases, would you not be cutting power to the Gunn oscillator, then powering up, and rapidly taking a reading? Wouldn't the the same frequency fluctuations come into play?
If instant-on is doing this cold start, does an instant-on capable gun wait the second (or so) for the Gunn oscillator to come to operating temperature before taking a reading?
Think of it this way, instant on is the full power, and it has been proven to be accurate with out question.
POP is only useing those short burst 67/16 ms, besides the fact that it is so weak, the radar guns own processor can barely get a reading, let alone it has been proven that it is not very accurate.
