8905 Precision Sensitive LCD Digital Tachometers

Standard model tachometers are used on all 4-stroke outboards, all gasoline engines.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.
