    It actually works pretty well. You have to know approximately what the rpm is and tell it, along with the number of cylinders, then it locks onto the appropriate part of the waveform it hears.

    In some planes, 50-100 rpm difference can be the difference between green zone and red zone. Get something you can check. The optical unit when pointed at a fluorescent light should read 3600. Mine reads exactly that.
