how far can their guns shoot?

[texasspeed]

say your driving down a highway will a couple of little hills every once in a while, and say ive got a v1 and im just driving driving driving, then my v1 picks up a k or ka band and it takes a while until i get eye contact with a leo...my question is, even though the v1 picked up the signal from a radar gun, how far away can he pick me up on a hilly highway or even a flat highway? also how far can a laser gun shoot?i hope that all was worded good and was a decent question..

I don't know about radar, but laser can get readings as much as 7000 ft according to a video on here a few days ago. There was no way the operator knew what he was targeting, just that he got a reading. Realisticly the max is probably 2000 ft and reliably 1000 ft or less.

For radar: Your V1 can pick up a signal further away then the LEO can read your speed. For your V1 to see the signal... it (the radar signal/wave) just has to reach the V1, for the officer to get your speed, the signal has to reach you car, bounce off of it, and get back to his gun. Given optimal conditions your V1 can see a radar signal for well over 10 miles. On the other hand the LEO under optimal conditions may be able to get a speed reading on your car at a mile or so away (That it optimal TEST conditions), that would almost never ever ever happen in real life. There is a chart on here that show vehicle size to speed reading range. For the LEO to get your speed he has to be in the Line of site.

(Note that LEO's use instant-on, which means: the radar unit is only on when the LEO turns it on [When he/she sees you they turn it on] and at that point, the LEO will have your speed before your RD gives you time to slow down.)


For laser: This is a line-of-site device (on both ends)... for the most part LEO's only set-up in a spot when using laser where: If they can see you, they can get your speed. Also your V1 will most likely only alert if you are the car being targeted... though in some cases the LEO may hit a car in front of you which causes the beam to 'scatter' where the V1 (which has excellant laser detection) will pick this up. Bottom line though is this: Even the V1 (with its amazing laser detection) is worthless against laser, if you are being targeted by the LEO, they can get your speed, and without other countermeasures (laser jammer, Veil) they most likely already have your speed as your V1 is alerting. A rare exception may be a very low-profile dark colored car (think Corvette with pop-up headlights in the recessed position)... you may get a second or two to slow down as the V1 alerts, but thats nothing to count on.

I will quote from a previous post:

Radar from a gun can get your speed in the best conditions at approximately a maximum of 3000ft in moving mode, and a maximum 5500ft in stationary mode. In most cases moving radar has about ½ the distance of stationary radar so the reaction from a RD should be different.

I forgot who said this, but someone on here said that they don't get your speed reading until your V1 is close to full bars.

To plagiarize one of my previous posts:

The maximum possible target range will vary from vehicle to vehicle depending on the radar cross section. For example, here's a Car & Driver test from way back in 1979(!). They used a Kustom KR-11, results are in feet.



But of course, different models etc will have different maximum ranges against the same vehicle.

A more recent study against some current guns can be found HERE. (It might be wise to take the absolute results in this with a grain of salt, considering who the author is.)

The target vehicle for the Stationary-Mode Maximum Range test was a Special Service Package Ford Expedition. This vehicle was otherwise used as the radar vehicle. For the Moving-Mode Maximum Range and Same Direction Maximum Range tests a Nissan Maxima was used as the target. All guns were Ka band except the Genesis II Directional which was K-Band.



To sum things up, it is generally a couple thousand feet to over a mile depending on the vehicle, the mode, and the circumstances.

On the other side of the coin, Speed measurement Labs testing has indicated that todays high-end detectors can alert to the radar at over ten miles away from the radar source, on straight, flat, line-of-sight terrain.

So, just about any modern radar detector is technically capable of alerting to police radar at several times the distance at which the radar gun can acquire your speed.

Now, some people might look at this info and conclude that any detector would be good enough, since it has the ability to alert farther away that the radar can acquire a speed. Nothing could be further from the truth. You just don't see such extreme straight, flat, line-of-sight, constant-on situations much in the real-world. Generally, the range is limited by terrain obstructions, aiming, instant-on, etc. Having a sensitive detector isn't about getting a three mile alert where another detector would have only given two miles. It's not about getting a 30 second alert while another detector would only provide 20 seconds. It's about getting that 1-2 bar alert over a hill, or when instant-on is being used up ahead. The point of having a sensitive detector is that there will always be situations where the more sensitive detector is capable of providing advanced warning, where a less sensitive detector would not.

my MPH python series II k band in stationary mode about 1 mile away and in moving about 3/4 of a mile.


my talon radar gun ka 35.5 in moving about 3/4 of a mile also i . stationary mode about 1 mile also

I ran my C6 at TrooperX' Stalker DSR last year and he wasn't able to clock me until 800 ft on Instant On.

Constant On he got me at 1000 ft once but there was a small lag. Typically when he shoots IO he waits to 1000 ft or less. One IO shot he wasn't able to clock me at 500 ft but he was trying to trim the shot so the V1 would not alert.

He was never able to get the Stalkter to clock the C6 in Instant On that didn't trigger the V1 nor was he able to satisfactorily clock the C6 quick enough to be confident the detector didn't provide some warning.

(Note: he was easily able to lock the vette with the SR7 not alerting.)

These little flybuys were pretty casual and so I didn't sit down and write up a shooting plan he just shot the me a couple of times and I shot him a couple of times while he drove my car. All of this was stationary by the way.

I'm not sure if I like hearing this or not, it's comforting to know the C6 has such a small radar cross section. The bad side is does this make you a bit overconfident?

Good info though.

Well, I'm not sure this is a good example of range testing since he knew where I was coming from and waiting to shoot me specifically. Usually he would wait until the target was visibly speeding then target it. One things for sure, the Corvette does not throw up blanks on sub 500 ft speed locks on modern radar guns. The technology has improved.
