Introducing the ScanGauge III!

The newest update from ScanGauge can help you monitor your vehicle’s most vital systems and provide the kind of real-time information you’ve been missing. Features include built-in digital gauges, five sets of trip data and an easy-to-use Scan Tool that reads and clears trouble codes — all in an ultra-compact design that installs in minutes.


Worried about where to mount the unit? The ScanGauge III includes a widshield suction cup mount. If you're not a fan or perhaps this is too conspicuous for you, check out SCP's 3D Printed Scan Guage III Mount, linked below.
