TOPDON is a popular brand offering a wide range of these more-capable scan tools depending on your specific specialized needs. TOPDON sent me this unit called the AD600S (a.k.a. ArtiDiag600S) for review, which is advertised to have 8 reset services and 4 system diagnostics. Depending on what you need a diagnostic tool for, you should take close look at the capabilities of the specific unit you’re looking at, as they have many different models with differing features.
