The speed you say that you were caught at would suggest that you would have been dealt with by way of summons, and that you more than likely signed a HO/RT/1 for the production of your documents.
Now, for the Pro laser 2 I am no expert in I am however fairly competant in the daily usage of the Lti 20 / 20 which is the same principal of operation and guidelines.
So,as for the distance of 962m well thats a fu***ng long distance to check a vehicle let alone see the fu***r
. The CPS guidelines for a safe prosecution is recommended not to target vehicles over 300m in distance from the officer.
It also states that you should strike the number plate in order to emmit any errors being fed back through the machine. Now I would hope that you have made a mistake in the distance, if not then I would suggest if you plead not guilty, it would be withdrawn by CPS for the above reasons.
I sit here typing and trying to recall the longest distance that I have tried to get a vehicle from and I would say it was only at most 400 to 500m and that was struggling and I have got very good eyesight, but I would never dream of prosecuting off those distances,mainly as a trial to see how good i am at locking onto the vehicle, after all as it has been said how can you truthfully say that you formed the opinion from that distance.
I have however done a check way off and used the check to see if it is going to be over or under the limit.
If you want my opinion and it is only based on what you have wrote then if you challenge it , i feel that you have a good chance of getting the result you want, but it all depends on the CPS guidelines if they are the same all over the country which I have no reason to doubt that they are.
So, good luck and keep us posted on the outcome it would be interesting to find out if it proceeds or grinds to a sharp halt.
