Before you buy any "diagnostic scan tool" think of tomorrow.

Look at the development of the tool, the after sales support of the product and it's coverage of your key vehicle brands.

Plus as Mike correctly said the diagnostic tool is only one "leg" of a three legged milking stool.

Automotive training is a must to keep up with the developments within our industry.

As is IT, a fault code is not a lot of good if you don't know how the system works and don't have a decent wiring diagram to work from.
