ScanGauge II

With its integrated trip computer, digital gauges and diagnostic scan tool, the ScanGauge II tells you just about everything you need to know, whether you're driving your car or wondering why there's a "check engine" light glowing.
The trip computer provides real-time feedback while simultaneously tracking three sets of data. The digital gauges give you ultra-accurate speed, RPM and MPG data while you drive--a great way to see how your driving style impacts your mileage! The OBDII scanner reads trouble codes and helps you diagnose potentially expensive problems.
Simply connect the ScanGauge II to your vehicle through the OBDII port using the 6-foot cord and turn the ignition key. It automatically connects to your car's internal computer and starts collecting data. You'll be driving smarter and saving money in no time! Measures 4.8" x 1.5" x 1.0". In Black.
