Anyone fought a ticket in Colorado?
Both laser and "radar" radar guns are based on the dopler shift of the signal from the speed of your car. This shift, is VERY SMALL... usually no larger than 100 hurtz even if you're doing 60 mph... and because of the high frequency of the signals they use (terahurts for the laser, and mega hurtz for the radar) and the dificulty of making a phase descriminator (or very high order filter) to measure the change in frequency due to dopler shift, they have to calibrate the guns on a regular basis.
It is entirely possible that his gun was off calibration (especialy if it was a radar based one, the laser based ones are typically better, and some of them actually using timing instead of dopler shift, aka I just shot, it hit the car, came back, how long did it take, use the speed of light... ok he's that far away, do it again (in like .00001 seconds) ok, that's how far away he is now, now we know how fast he's going...) so make sure to have them check the calibration records of the gun and make sure it was calibrated when it should have been.
My electromagnetics professor got off a speeding ticket once because of this... (she wasnt speeding, but still got a ticket like you)...

I do believe the officer who wrote the citation must be radar certified in order to write speeding tickets.
Maybe you can find out if this officer was certified, if they weren't, you are off the hook.

The more wrong the cop is, the less likely you will get off. Its a matter of pride for them, and a big F-U to you for calling them a liar. The judge will never take your word over theirs, you have to prove he is wrong, or prove his interpretation of the law is wrong. Or get lucky, for example a lost ticket.
My personal experience with tickets in Colorado:
1) Speeding in Aurora, +21 or so. Had to go to court, plea bargained.
2) No insurance card (but had insurance), 7 month expired tags. Renewed tags, went to court, presented info, paid $15.
3) Speeding (wasn't) on I-25 N of I-70. Spotter cop wasn't even running his radar any time near when I went by. Went to fight ticket, ticket was lost. Case dismissed FTW.
4) Speeding in Denver, +10, photo radar. Argued that I was going 9.9 or less, la w states they can only issue a warning for first photo radar offense less than 10 mph over. Won.
5) Rolled stop sign (didn't) in Centennial. Cop was obscured by SUV turning left and large brick sign he was hiding behind. 2nd day I had my Z. At the time couldn't shift into 1st without being at a complete stop. Didn't matter, judge was a condescending *****. 4 points. Still satisfying making the cop show up to court and calling him a moron to his face.

If your defense in court is constructed around stating your new Z WON'T go into first gear unless you're at a full stop, YOUR credibility is at issue. The point is that unless you have a STRONG source of evidence, don't bother taking it to court. The time, cost and effort isn't worth it and you'll end up being frustrated.

Most lasers are now based on time vs. the Doppler effect. And yes, all radar and laser must be calibrated every year and all officers using them must be certified.
All agencies have programs set in place to have the units sent back to the manufacture to get re-calibrated and to have officers attend the course.
When you go to trial the DA will ask to see the calibration papers and the officer's certificate.
