Hardly. With modern speed measuring equipment, you have only microseconds to react. By the time you see (or your detector sees) the device, your goose is probably cooked. as i said, oblivious. not only are you prime meat for being pulled over, but you don't understand how traffic radar or radar detectors work. it's much more than 'only microseconds' to reliably lock a speed and a quality detector can give more than ample warning regardless. good drivers will watch for changes in traffic patterns, such as brake lights on vehicles ahead, changing traffic patterns, vehicles in the median, etc. in fact, you should be doing that all the time, regardless of whether you're speeding or not. : What is tough for Radar to do is isolate an individual vehicle to : clock.

Very interesting. You are aware, of course, that the Duck is a retired cop? yes. you are aware, of course, that more than just cops know how traffic radar and lidar works? it's not secret. |

So there are times when slowing down after you understand that car you coming up to with the intention of passing is a CHP cruiser and your ticket is as good as written. only if you're oblivious. Not really. yes really. If you are close enough to ID the vehicle in front of you as a CHP cruiser and react, the officer has already clocked you with his rear facing radar which cycles every 3 seconds with the forward facing unit. if he's using radar, particularly rear facing radar from his stalker dual, then he doesn't need to be close enough to id the vehicle. he only needs a radar detector. in fact, even a crappy detector will pick up radar aimed directly at it with ample warning. Also, there are many beats where you will find more than one CHP cruiser which is not your typical "Black & White". There are quite a few all white and some bronze/grey Crown Victoria Interceptor and Dodge Charger Pursuit vehicles out there without light bars. (However they still have a subdued door logo. http://home.comcast.net/~tvigil/52-CHP-SMPV_02.jpg http://farm6.staticflickr.com/5133/5...45708eee_z.jpg ...and sometimes it isn't a patrol car at all: http://latimesblogs.latimes.com/.a/6...5871970b-600wi that doesn't matter. all of those cars have a distinctive profile. those who pay attention will notice it. oblivious people won't. Naturally California isn't the only State to use such vehicles. What is tough for Radar to do is isolate an individual vehicle to clock. That takes experience and/or LiDAR. supposedly, they estimate the speed visually and confirm it with radar (or lidar), so they already know which car it is. It is simple enough to check a vehicle's relative speed against other traffic to pick it out of a crowd. That is usually the big "tell". exactly. However, some thing a little more presentable in Court is usually needed. and then they confirm it with radar, lidar or pacing, which they used to do before they got their high tech toys. on the other hand, a lot of times they just wait for the overspeed alarm to go off. So you have spent some time in a radar equipped cruiser have you? I have spent some time in Chevy Caprice cruisers, and Crown Vics. Though the last Crown Vics I drove were not equipped with traffic equipment, just radios, door spots, rear shelf lights, and grill lights. what does that prove? you do realize that knowing how to use traffic radar and lidar is not secret, right? |

The same goes for the cruiser you come up on and you have managed to slow to the speed limit, in what you believe was good time, only to find him slowing down to allow yo to pass him and to find he has lit you up to pull you over.

However, some thing a little more presentable in Court is usually needed. and then they confirm it with radar, lidar or pacing, which they used to do before they got their high tech toys. Pacing and eye-balling has always been a fall back position for patrol officers, and still is. It is not as watertight in Court as it once was. on the other hand, a lot of times they just wait for the overspeed alarm to go off. So you have spent some time in a radar equipped cruiser have you? I have spent some time in Chevy Caprice cruisers, and Crown Vics. Though the last Crown Vics I drove were not equipped with traffic equipment, just radios, door spots, rear shelf lights, and grill lights. what does that prove? Nothing other than I know of which I speak, and you seem to have some insight as to how officers in radar equipped vehicles use that equipment from whatever research you might have conducted. you do realize that knowing how to use traffic radar and lidar is not secret, right? Knowing information available on the internet and actually working with VASCAR (no longer used in CHP vehicles, but use by some Cal SD's and PD's), radar and LiDAR is something a little different. Also different jurisdictions use different equipment. For example both San Luis Obispo & Monterey County Sheriff's Departments do not use Radar, but most municipal PD's in both counties do. -- Regards, Savageduck |

Does any camera come with a laser pointer?
Peter Jason asked:
Like laser pinpointing on rifles and pistols. I need it for shooting from the hip at weddings and the like when the exposure is set for pinpoint. Sort of. The Sony DSC-F707 has a built-in laser pointer that enables it to auto-focus in the dark. The camera is obsolete in many ways, and long out of production, but it was a great camera in its day. I hope to see some of its ground-breaking features again, including the laser. The F707's laser isn't for "shooting from the hip". It rapidly draws a pattern to provide lines with enough sharp contrast for the auto- focus. I could never even see it from behind the camera, though my subjects in front could see flashes of red when it kicked in. The laser is too low power and too fast moving to damage anyone's eyes. There is a bit of a design flaw: The F707's laser emits from behind the filter ring. It worked fine through the multicoated UV filter that I kept on mine for protection, but other filters can render it worse than useless. The F707 is great for "shooting from the hip" though not because of the laser. Its lens-centric design with articulated body lends itself to a wide variety of viewfinding styles. Great camera. -- --Bryan |

Yup! There is a great variety of equipment and technology which are variations on a theme. I also believe PA uses a later version of VASCAR in its speed detection armory. For example both San Luis Obispo & Monterey County Sheriff's Departments do not use Radar, but most municipal PD's in both counties do. what do they use? lidar? something else? Both of those SD's use the Mk I eyeball on patrol (as discussed earlier, that is a method still employed), and will usually leave anything but the most blatant offenders to CHP and local PD's. -- Regards, Savageduck |
