8402 Series Precision Sensitive LED Digital Tachometer - Black Standard

Standard model tachometers are used on all 4-stroke outboards, all gasoline engines, as well as diesel engines equipped for mechanical senders (typically Detroit, and older diesels). The Switchable Medium and Switchable High tachometers are field settable and are used on engines equipped for mag-pickup sensors (typically newer engines) which produce output pulses correlated with the number of flywheel teeth. Medium tachometers are designed for 13 to 90 teeth; high tachometers for 91 to 255 teeth. When purchasing a tachometer for an engine with a map-pickup, you do NOT need to know the number of flywheel teeth.
