Reversing sensors

  1. Has anyone fitted reversing sensors to their van?
    The sort that sell on eBay for around £10?

    Was wondering if the rear engine location would cause problems with them.
     
  2. I fitted a cheapo set to my Kia Sedona and they are great. cant see that it would cause a problem. Just make sure you get the ones designed for metal bumpers.
     
  3. I fitted parking sensors to my camper about 10 years ago, they look very similar to the cheap ones on ebay now. I paid about £30 at time for 2 sensors and a buzzer with lights.
    I remember when I brought it and opened the package it said not for rear engine cars. But I fitted them anyway and they work fine.
    It also helps to let you know when you have found reverse gear as it gives a single bleep to let you know they are working.
     
  4. I think i'm just gonna chance a tenner and see how what they are like.

    I used to fit them for a living - I don't understand what the issue is with rear engined cars?

    A couple of things you need to be mindful of are:

    Height - relative to the road - too low and they pick the road up and alarm, too high and they miss things like curbs.
    Angle - they need to be on as horizontal surface as possible - again, pointing down and the pick up the road, pointing up they miss curbs etc.
    Spacing - too far apart and they miss sign poles for example, so space them so they give good coverage.
    Orientation - most sensors have to be fitted a certain way up, check the instructions (e.g. round ones have a flat spot on the back case, or a small dimple on the front face).
    Activation - if you run them off the reverse light, on some vehicles this is in the tailgate - find the cable run and test for reverse light (assuming it isnt CanBus).
    Buzzer/display placement - don't put the buzzer so far away you cant hear it - extend the cabling to the front of the van.

    On a late bay I think the first two above are dictated by the bumper - so check the instructions for heights.
    Spacing needs some maths and an idea of coverage.

    Activation is the challenge - if you don't have a reverse light - what are you going to trigger it with?

    I've got a great big steel bumper on mine. Seems to do the trick, you just stop reversing when the van stops moving backwards. :D

    Or you could always do it the old fashioned way, and turn around and look behind you and stop when you get close to something....
     
  10. Its not easy when theres a westy wardrobe right behind the drivers seat. Vision through the rear window stops about 6 foot from any object too.

    Reversing sensors!?
    You could just learn how big your bus is?

    That's why you look at a space before parking in it!

    Simply because I don't need it.
    You can buy electric tin openers but that doesn't mean I'm going to buy one.
     
  16. I will, for once ;), agree with baysearcher. Surely you should know the size of your vehicle and not try and park it in a space too tight for it, it's all about spacial awareness. I'm no techno-fobe but it is making people too lazy and reliant. I can 3 point turn a 7 1/2 ton lorry on an A road without hitting the curb using only the side mirrors. If you have something blocking your view in a bus, remove it.
