What is the difference between a $400 OBDII diagnostic scanner and a $40 one?

DBCooper5770B to Mechanic Advice@gearhead.townEnglish · 10 months ago

I have been researching this on amazon and other places- some of the more expensive ones say they have advanced features? what does that mean? what does a $400 one do that a $40 doesn’t? Unless i can hit a button the $400 one and it actually fixes the problem, otherwise, i can only imagine it has more codes for complex issues?
