In the UK all the forces now use Laser only. I have not seen a radar based system in years. We also have the fixed SPECS camera system which logs your numberplate on sets of cameras a known distance apart and works out how fast you were going on average between the two. The newer SPECS 3 system has just gone live and that uses networked cameras so will work on different streets and lanes!!

On top of that we have red light cameras, front/rear facing speed cameras using inductive loops in the road and front/rear facing radar based cameras. Licence to print money or what!!

Most UK drivers who have bought detectors, use GPS based systems which know where all the fixed and approved mobile sites are (all sites must have approval). The one I use - Road Angel Professional Connected - is linked up via the on board mobile phone SIM to provide real time updates from other owners, assuming of course owners are updating! We have som many different camera based systems now both fixed, semi-mobile and hand held that it's becoming a serious issue (and speeding is a serious issue I know) that enforcement has lost a lot of credibility in the UK. It's seen as another stealth tax. One camera at the bottom of the M11 motorway to the East of London makes the UK Governement £500,000 a year (around $800,000US) at £60 a pop + at least 3 points on your licence (12pts = 28 day discretionary ban), and that's just 1 camera!!

Oh, and should you decide to fit a laser jammer, they are detectable by the speed gun when they fire back and you get prosecuted for impeding a Police Officer in the execution of his/her duty, and you lose your car!

Good in Great Britain innit!!
