I don't need a lecture just advice on a radar detector please mate.
I'm not a 17 year old boy racer,just require some extra protection.
Please dont make out you never speed,be it on purpose or not.
I got banned for speeding btw just a little bit excessive on the motorway at 4am
With all due respect, it sounds like you do. You have been convicted of doing 154mph on the motorway, which is nothing short of stupid. Before you've even got your license back you're trying to get recommendations on devices that will help prevent you from getting caught speeding.
There's no magic trick to not getting caught. It's actually really simple. Follow the speed limit and you wont get convicted of speeding. A large number of motorists manage it, so you should be able to. It's a lot cheaper than a radar detector as well.
Oh, and for the record, I don't speed - If I want to drive fast i'll go to a track. Job done.
So you never cruise at 80mph on the motorway? Your speed never strays above 60mph on an a-road? Bullsh!t! 
No. Why is it so hard for people to believe there are people who stick to the speed limits?
When I was younger, I used to speed a bit (not a lot). Came to the conclusion I rarely got there any quicker and it wasn't really worth it. Now, I stick to the speed limits. I drive a car that makes a hobby of drinking fuel in insane quantities. On the road, I like to keep the very low MPG up as high as possible.
On track, however, it's a very different story!
To OP, i'm not trying to piss on your chips - just saying that perhaps you need to change your mentality if you want to keep your license.
