9500i

**Greg** · 02-22-2007, 01:49 PM

Anyone have any concerns regarding a possible reduction in response time to a threat with the 9500I having to sweep X, K, KA, KU, POP, SWS, LASER and now GPS Coordinates for marked locations and frequencies.

Like most computers as hard drive space fills up, the slower your computer will work.

How many marked locations can the chip store?
And when will the quantity of marked locations cause a noticable lag in response time?

Something to think about when you drive around marking every Bank, Convenience Store and SuperMarket.

I cannot give you a concrete answer for all of your questions. However, I believe that the top detectors all use DSP circitry, so no "sweeping" is done. Rather when the Detector recieves a radar signal it compares it's frequency with the known bands that the police use and acts acordingly. I am sure that someone else here can give you a more in depth explanation.

With a few exceptions, "sweeping" is done in all modern day radar detectors....

But I wouldn't worry much about response time. As a matter of fact, what limits response time in most detectors isn't caused by a slow sweep, but is actually done on purpose to reduce false alerts. The manufacturers use filtering algorithms which require that a signal be present for a certain amount of time in order to trigger an alert, commonly a few hundred milliseconds (except in some circumstances such as POP)...

I don't know if the 9500i works like that but there's a possibility.

How many marked locations can the chip store?

Others have stated it can handle 5K locations - got no concrete evidence on that and the manual didn't even state that number. But let's just say 100 for example. That's a lot of locations. If the false alert is in an intersection and speeding is not a concern, putting it on A mode will do the job. But if you have to use the lockout feature, i don't really think that you will need 50 lockout areas on your daily commute. I drive an average of 130-150 miles a day and only lockout less than 10. Maybe more in heavily urban areas. But locking out 50 or more is a lot in my opinion.

Note that SWS is not widely used as well as Ku band. POP can be turn off/on and i don't think this will delay the response time and in fact when POP is enabled, the 9500i is more sensitive to radar signals and you get a good amount of POP false alerts.. Also LEO won't waste his time doing rspeed checks in intersections and if he does, it will be very very slim for him to do that. Most citations we get is usually in the interstates, school zones, state hiways that have PSL from 45 - 70 . It's just a fact that we don't get speeding tickets in intersections.

I would suggest that you try the 9500i yourself. You will have a 30 day trial and return it back if you don't like it. You won't really be able to know all the capabilities the 9500i will do unless you try it yourself. I may be able to tell you some of it but you won't enjoy it if you don't ride with it. :wink:
