Anyone use those digital tachometers that are self powered and take their signal from one of the spark plug wires?? Are they accurate?

I haven't but I thought tachometers whether they are digital or analog readout got their RPM signal from the distributor not a sparkplug.

Also if you want a good digital readout gauge of any kind(Speedometer, tachometer, Trans, oil, antifreeze temp...) go to they are one of the best.
