Efficiency and Accuracy

Check the efficiency of the scan tool. It should be designed to pull up relevant, reliable, and accurate car diagnostic information.


If you have an iOS smartphone or tablet, make sure your scan tool is compatible with it. It would also be a lot better if you go for a device that works in both Android and Apple devices.


Determine the scan tool features you want and find out which device can provide what you exactly want. Note that devices with more features are more expensive than those that offer lesser capabilities.

If you’re willing to forego some features in exchange of a lesser price tag without compromising your work, then go for a cheaper device.

Brand name

Make sure to buy products only from reputable companies. Take time to check the background of the manufacturer and its reputation in providing quality and efficient tools.

Be careful with some cheap scan tools that are manufactured by unknown or not-so-popular makers, because a lot of them are not genuine.


Take time to do your own homework before settling for a scan tool you can use in your routine car maintenance works. Surely, all manufacturers would assert their respective devices as the best one available. The best way to verify and confirm all these is by listening to the advice and feedbacks of other people who’ve used them.

Always remember that having the right scan tool would not just make you an effective technician, but would also save you a lot of money.
