None of them have jammers. I was in the car with a buddy recently with a RA. I saw the little blacked out window on the front and asked what it was for and suggested remote control of some sort as an answer.
He said, no mate, it's a laser detector for mobile speed traps. Oh the humour to lighten up a work day.
Detectors aren't illegal in any way, shape or form. And the only useful detectors are radar detectors. Bell and Valentine make the best ones.
The plus point over things like Road Angels is that they only go off if the camera is active (which is more than handy on motorways with variable speed limits).
The negative points is that sometimes you don't get a lot of warning (as low as 50m sometimes).
Jammers, ARE illegal, laser jammers are only illegal if you're using them to jam police guns though, they use a licence free wavelength so you're not breaking the law by having one on your car, but police wouldn't see it like that if they ever questioned it.
Radar jammers do exist, and they are available, but not readily and not to the public. They're highly illegal to own and can even get you a 10 year custodial sentence for having one. Bit pointless too seeing as the only things that use radar these days are GATSOs and if you can't see them then you shouldn't be driving
