Autometer Pro-Comp Memory Tach

This Pro-Comp Memory Tachometer features a rugged air core meter movement for superior accuracy. It works with standard or electronic ignitions. It includes a remote mounted switch (so it can be mounted close to the driver). Peak rpm memory recall lets you choose the best gear for the track you are racing. It is also water resistant with a waterproof remote switch. The tachometer face can actually be hosed off after a dirty race. The tach face measures 3 3/4" and fits in a 3 1/2" hole.
