What is the approx. distance the radar willl alert you? Several reviewers mention time units, but time varies with speed...

The answer to your question also varies. If the laser or radar can't read your speed, then your detector may not be able to detect it either. I have driven on rural roads, highways, hill country and where I live and drive, mostly Houston is flat. I have had this detector for over a year and it has never failed me so far. You won't be disappointed. I have always been alerted much before I am able to see the cop, giving me ample time to slow down.

It does a very good job with distance when your traveling on highways, at times when my detector went off I saw nothing in the area but I slowed anyway and sure enough there was a patrol car just ahead. I'm guessing that the distance would vary with the amount of "gain" the police have there radar set at. I have had mine for over a year and it works great!!! You wont be disappointed

Most likely he had radar off - it only detects radar when its on - it will definitely work, mine works just fine, even at a distance and over hills etc.

I have found mine to be very accurate, although sometimes it will be off usually about a quarter mile for a 10 miles ruen. I think it has more to do with the movement or adjustment of the satelites rather than the watch, since I have noticed on the peaks website that sometimes the course is really off and has me starting out in Lake Erie. There is not really much you can do about it and all brands pretty much use the same gps. If I am running a course for time, I always measure it by my bike or car for better accuracy. I did do a 10 mile race last fall and it showed 10.07 which was very good. Trees and turns or switchbacks can through it off as well.

Ka is laser. If you see it on it is never a false alarm. Xk I believe is regular radar. I really like this detected allot. I do allot of highway driving and this thing saved me several times. People get frustrated with detectors and say they don't work, but remember. No matter how fancy the detector is, if the cop doesn't have his radar on, you won't get a reading. All in all though, this thing is well worth its money.

I never had a problem. I picked up radar as far as a mile away. I had Cobra's & their junk.

Big Marcus, A very big yes on Ka detection. My commute each day is through SE MA and RI and my whistler always alerts me well in advance when the stateys are setting up a trap. As for GPS, not sure since neither model that I have owned had that feature. Hope that info helps. BTW, for the price, Whistler can't be beat.

Every time I see it go off there is a patrol car sitting or driving by. Sometimes it reacts to doors at super markets like wall mart and when emergency vehicles are active they also set it off. But other than that no it does not alert you unless it is something that actually sets it off. It will constantly beep with a bar telling you how strong the signal is. The stronger the signal the faster the beep. Also it will let you know well in advance about a radar and will continue to beep until out of range.

*UPDATE/CORRECTION* I just went back and read my original review, and it looks like those settings are range in meters for motion detection, not time in minutes that it stays on. I'm pretty sure it is range, and there's just a set time it stays on per trip, but I'm not sure what it is. Seems like 10mins approx. Sorry my 1st answer was incorrect. Was accidental. ORIGINAL ANSWER: Mine has 1M,2M,5M,10M,20M choices. For me this product has some drawback, so u may want to read my full review before buying.

Seriously, this sensor works only part of the time 5 feet or 100 feet away. I strongly suggest you use a reliable solution for anything that is important. It will false alarm, or lose track of the sensor or not alarm when it should. Then sometimes it works fine. I have 2 base units and 4 different sensors. None work reliably.

Mr. Holmes is correct, there are a lot of variables that can impact the range of any radio. Two miles is probably a good rule of thumb, however.

Detection range side to side is real close to 180deg. It is quite sensitive of my movement even at the end of this range! Also, it does not seem to be activated by tree limbs blowing - amazingly. Distance for detection of a person (for mine at approximately 10 feet high) is about 40-50 feet. I am VERY happy with this item. It lights my entire path from the car to the house and stays on while I am moving. Very easy to adjust to preferences too.

It's a radar capability, it has the internal software and processing power to alert you of the KU band, and I have gotten a KU false alert before. It can pick them up, it's just not often if you ever do.

actually no....The gps used is for know location of speed light camera and police speed trap. and the radar also warn you when speeding over the desired overages that you set.

Yes, the detector gives different sounding codes based on the type of 'radar' being utilized. There's also a voice recorded in the unit to tell you what it is. So you'll get something like "beep, beep, beep, K-Band" or "... X-Band" or "KA-band" or "Laser Alert". It is, to my knowledge and from my experience with the device, 360 degrees of detection with the possible exception of laser. I think the laser is somewhat limited to a wide front angle and a wide rear angle. Obviously since laser is a light-based wave, the side of the car may be interfering with the device's ability to sense it. I hope this was useful.

I'm not sure of the exact range of this alert system. I had a distance of about 1/3 mile from transmitter to receiver. Regardless of the range, I would not recommend this product to anyone as it only worked for a few weeks before it started giving false alarms or didn't alert when someone was actually coming down the driveway. Look elsewhere for an alert system!

Yes, if your vehicle's speedometer is accurate. Just point the radar gun at a fixed object while your vehicle is moving, and compare the reading with the speedometer.

I would guess that it picks up radar 2-3 miles in advance if they are pinging other cars. as far as updatable, I do not know since I just purchased mine recently but would be surprised if it was not
