A lot of standard radar detectors have display that anyone can use. It's not just a "deaf friendly" radar detector that we could look for.
Best answer, drive at the speed limit. The reason why US is using up so much gas is because people go too fast on highways, also too many stop and gos in cities.
I have NEVER used a radar detector before, guess what? I never got a speeding ticket. I got pulled over a few times but they never gave me a ticket, call me lucky. I guess.
How is it "deaf friendly"?Oh, I got it.
I found Valentine One, that looks like nearly to be deaf friendly device.
Yeah, radar detectors don't work against lasers... and vice versa.Wrong, Not all cops always use radar. They use LASER GUN!
Then your radar detectors is not work for laser. I have radar/laser detectors.
Remember most cops use laser gun on highway and some cops use radar for city.
Good news. Laser/Radar guns are not work during rain,fogs, and snow. Heheh
When I drove to Texas a couple weeks ago, I saw a cop far away. When I came closer, I saw him using laser.Depent what type of detectors you use.
My detector got warned (Pro LASER flash one time) to me and I don't see any cops on highway but I drove slow till 1 mile later and I see cop.
Other time.. My detector got warned but I don't see cop till I take over the hill then I see cop there.
It's true.

Well, I heard of a case down in Florida where the trees were clocked going 85 mph. Er...interesting...of course they had to throw out all the speeding cases.
