The ST400 Recording Tachometer was Stack's first product, which in its day (more than twenty five years ago) provided the only on-vehicle solution for accurate RPM display and logging. As a direct result, this unit immediately gained widespread acceptance with Formula One teams and all forms of professional motorsport.

These tachometers have a 3.5"/88mm bezel and are a direct replacement for most standard tachometers.
