Electromagnetic Parking Sensors

leylie

Hello - does anyone have any experience of these please? I'm having trouble finding recent reviews.
Thank you

What about them?

Personally buy a proper kit.

Waste of money in my experience, utterly unreliable, lots of false alerts.

Look at the expensive cars, £100k plus, they still use the "classic"ones, that should tell you why. They just work.

gabitzul - Thank you for explaining why you don't rate them

forgotmyname - thank you for your opinion

I had a car once with aftermarket rear parking sensors fitted. There were no visible circles, so I assume they were fitted on the inside of the plastic bumper. They may have been the type you mention.
My tests suggested there were 2 sensors about 4ft apart. They worked, until the bumper was wet from overnight rain then they were hopeless until the raindrops had been blown away.

Sounds like the sort - interesting comments thank you, especially about the rain - and having only '2 sensor zones' as my understanding was that the whole width of the bumper was covered. One of the main reasons I was going for this sort!

Have you considered a reversing camera? I find this more useful than sensors.

hello.
i fitted similar ones to my alfa, they are very expensive and you have to remove the bumpers to fit the metal strip to the inside of the bumper.
I have since fitted ordinary cheapish ones to other cars ,and they are a lot better , cheaper(£20), & easier to fit for the diy man.
Dont waste your money.;)

Thank you - I am also considering a camera as there was one in the test car I drove, so your comment is helpful.
I'm actually fairly confident with reverse parking - but this new (to me) car has a much shorter bonnet than I'm used to and I can't actually see the front of the car, I was hoping the electromagnetic sensors would help me there.

Thanks everyone for your comments - I'll certainly re-consider my options. Maybe I just need to give myself more time to get used to my 'new' car!

Ultrasonic are the cheapest and most reliable for now when it comes to reverse drive sensors.
Only metal (electricity conductor) obstacles can be reliably detected by electromagnetic sensors. Not sure about brick wall.
Electromagnetic sensing is doing good job in wireless parking sensors for vehicle detection fitted into each parking bay to show real time availability. This technology is becoming increasingly popular nowdays and gets integrated into mobile parking apps.
