There's nothing worse in my mind than discovering a problem when an idiot light goes on because it's usually too late to prevent the problem.mThat's where the Scan Gauge II comes in handy for me. Now I can monitor my transmission and engine temps hauling my popup camper on road trips. Combine that with the ability to pull codes and clear them it's indispensable in my book. Already love the readouts and have had a couple friends buy one after seeing mine in action. There are cheaper alternatives but this is a case of getting what you pay for.
