Paul correct me if I am wrong the only problem with the Lti 20 / 20 is the ones fitted with the camera the stand alones so to speak are 100% I have tried all three lasers that we have and could not get any spurious readings no matter what. We take them to court regularly and show all how they work and let them shw us how they are defective?. 100% successful convincing prosecution. I stand to be corrected though.

I've seen slip effect with my own eyes, and with equipment identical to Home Office approved equipment. It's FAR too easy for such an error to take place unnoticed in both Police hand held operation and in a camera van (connected to video) configuration. I am certain that the equipment is unsuitable for gathering evidence 'beyond a reasonable doubt'.
When the Home Office tested laser speed meters for type approval purposes they did not test for slip effect. If they had, I'm sure that they would not have given type approval. The bottom line is that it's a massive cock up by Home Office staff.
