I was lookin around on you tube at widebands and i was wondering, how do you really read one with it jumping around all over the place?? I saw some stay steady a little bit but they were mostly all over the place! sorry for the ding bat question but i was wondering....haha

 

I think you're looking at the narrow band. The widebands have a number read out on them

 

Yep, the pos worthless narrowband gauges are the ones that jump around all over the place...
