Longacre 4.5" SMI Accutech Memory Tach


Stepper motor tach uses a small electric motor to drive the pointer. It is more precise than the more common 'aircore' instruments whose accuracy can be affected by the windings. Many professional race teams - NASCAR™, etc. – are switching to this style of tach for the improved accuracy and response.
