Built for a lifetime of service under the harshest conditions, this is the no compromise tach for no compromise builds. Record up to 80 seconds of engine R PM data and playback at slow motion speeds to analyze vehicle and driver performance following a run. Identify key performance data such as burnout, launch RPM, tire spin, gear changes and engine speed through the traps to fine tune your setup and trip the win lights.
