exhuast jacks

Bottle jacks are great - providing you can get them under a lifting position. It can be a bit awkward if you have a puncture (or roll a tyre off a rim!) in sand. Might make it difficult to get a jack positioned without a bit of digging and re-positioning. You will also need a good base plate.

You can use an exhaust jack just about anywhere - providing you have some form of protection from sharp objects. You can use old bits of carpet, chaff bags, etc, even on the bitumen.

Like many others, I carry both and simply decide which one to use depending on the conditions at the time.....

Felix, the first time i used my exhaust jack it worked fine only problem is when i deflated it i noticed it was damaged slightly from when it moved while being inflated. Make sure the protector ( carpet or whatever) is more than large enough to cover the top of it and check to see it doesn't move/slip onto sharp protrusions under the vehicle while being inflated.

Now can anyone tell me if they can be repaired using something like a vulcanised patch, or know of someone that can do a professional repair. Although mine isn't perforated it is damaged and i wonderif it can be repaired.
Or is it a cactus job?

thanks for all the suggestions, i now feel more comfortable about using an exhaust jack, will take a bottle (jack) aswell to be sure.
