Having had a defect on the ignition system on the daughters Grand Vitarra, which is now fixed apparently after I replaced the two plug leads and to be safe the two coils, I was thinking of getting one of the scopes. Now the technology and stuff that works these tools are way above my paygrade but with a little guidance and hard work I reckon it will be invaluable as the technology on the cars get more and more complicated. Anybody have any experience of them and if so any recommendations as to the best one to buy. The channels and bandwidth I suppose is important but I would like to know what they do!
