My older craftsman inductive with power from the car's battery worked very good when there was not an MSD involved, but did not work very good on MSD. It had a tendency to jump around a lot. So I bought the MSD self-powered. It works very well with the MSD, steady as a rock. And the self-powered feature is very handy so I don't have to hook it to power when the battery is not under the hood.
