Two speedometers, one sensor??

Why have two speedometers, then? What's the point?

Do you have the perfect pass? I have two speedo's, but one is mechanical and one is electronic. The electronic is the perfect pass. Neither works on the water pressure method, both use the paddle wheel which is much more accurate. I did run into a problem Saturday where a little piece of algae got stuck in it, but I swam underneath, cleaned it and it is as good as new. If both are mechanical (tube type) I would think that two pickups would be standard, but this is the first Supra I have owned (VERY happy with it).
