Concluding on  best and affordable bi directional scan tool for car

And if you are a beginner you should go for the AL619 in terms of affordability but as an expert or experienced mechanic, you probably be better of with NT650. However, you may also consider  AD610 or the CRP429 as they are in between the first two.

And if you are a much-advanced mechanic and have the money, then you surely will prefer the

LAUNCH X431 PROS Mini models which is number 2 on our list or L. and the LAUNCH X431 DIAGUN. The  Launch PROS mini is best for those who are advanced but learning, while the VPRO works better for your shop.

As a professional, you may also love the Autel MaxiDAS DS808 OBD2 Full-system Diagnostic Scanner, especially for those who want something portable which can easily be carried around.

The FOXWELL’s NT630 Elite and other models will work best well for beginners on a budget as well but these cheap bidirectional scan tools are not easy to use and so will require some learning time to master the use properly.

Finally, the Autel Maxisys MS906BT’s camera feature is best for DIYers and professionals who want to record the issues they are diagnosing on the go.

Please note that your car model might not work with all these scanners so it is important you pick the scanner that will work with your vehicle, especially the cheaper bi-directional scanner. And if you are a mechanic who works on many models and brands of cars, then be prepared to spend a little more to get a scanner that covers and is compatible with multiple models of vehicles.
