VdiagTool VD30 PRO
Comparing Vdiag to other code readers in a similar price range, it can display more live data values and also display up to 4 different graphic values at a time.
VD30 Review
Ancel AD310
Ancel AD310 is one of the best-sellers on Amazon and I can see why. You will get full Global OBD functions, including some enhancements like engine live data graphs.
AD310 Review
Launch CR3008+
One of the best code readers I tried and the only downside was a slow reaction to pressing buttons when navigating in the scanner’s menu.

Ancel AD530
Other than classic Code Reader functions, it gives the ability to read multiple live data graphs at once, do a battery health test, or even display a list of possible causes for every fault code.

I also did a video with some of these code readers so you can see them in action.
