Now I'm not too happy with the idea of drilling holes in my lovely rear end but It really would make life easier when parking if I had some sensors.
I have come across some electromagnetic sensors. What do people think of these compared to the ultrasonic ones? Has anyone got them?
I'm concidering on giving them a go!
"Ultrasonic parking sensors
Ultrasonic sensors bounce sound waves off obstacles, using the ‘echo’ time to indicate how far away they are. A speaker in the car bleeps – increasingly frantically – as they get closer.
Pros of ultrasonic parking sensors
•The cheapest form of parking aid – aftermarket systems cost as little as £30; car manufacturers charge £300-£700.
•Sensors^detect objects even when the car is stationary.
Cons of ultrasonic parking sensors
•Ultrasonic sensors can miss smaller or narrow objects, and inclines can deflect the sound waves – a steep ramp, for example.
•They also only detect objects directly behind or in front of the car, and may not work if the sensors are dirty or out of alignment.
•Fitting usually requires drilling the bumper, but stick-on sensors are available (though unattractive).
•Ultrasonic parking sensors not be suitable for use with a tow bar.
Electromagnetic parking sensors
Electromagnetic parking sensors create an invisible electromagnetic field around the car’s bumper; any objects entering it trigger a warning sound. Currently used by Audi, Citroën and Fiat, among others.
Pros of electromagnetic parking sensors
•Suitable for use with tow bars, cycle racks, etc.
•Electromagnetic sensors are mounted inside the bumper, so there's no need for drilling.
Cons of electromagnetic parking sensors
•Electronic parking sensors are more expensive – prices start from £70 (aftermarket). The factory-fitted cost is about the same as ultrasonic sensors, however, at £300 plus.
•Electromagnetic sensors only detect objects once the car has started moving."
