Best OBD2 Scanners Overall (Tested in Real Diagnostics)
Published: March 3, 2025 · Last updated: May 23, 2026
I am running my own car shop and testing OBD2 scanners for a living for more than 4 years. These are my go-to scanners that I am using to solve most problems on most cars. They don’t focus on one specific brand, but rather to cover as many cars possible.
Quick Picks – I use these everyday!

Full comparison
The Autel IM608 PRO 2 is the best option for any kind of car business. If you are doing car service, used car checks or any car work including OBD2 scanner this one is best to boost your performance and finish more jobs (also good for key programming which pays well)
- Best overall for general car shop
- Good for key programming
- Overall service resets have better vehicle coverage then cheaper scanners
- Good to boost shop productivity
The Mucar 892BT is my main go-to scanner. It is tablet but still small enough to keep stored in glovebox so I always have it ready. Whether I am doing diagnostics, coding, or service resets, I am using this one first.
- Fast
- Easy to work with
- Great budget pick for shop to solve most issues
- Free lifetime updates
The Thinkdiag2 is my budget scanner to keep in second car. Same like with Mucar 892BT, with this one I am doing most of my tasks if I have only smartphone with me. It is also one of few if not only bluetooth scanner that can do full-system, service + codng combo (usually only tablets do all that)
- Fast
- Works just with smartphone
- Can do coding (rare for bluetooth scanneer)
- 1-year free updates
The XTool A30M is my #1 pick for budget OBD2 scanner. If you are buying your first tool, or you don't actually make money with car work, this one is gerat choice. Still can do lot of stuff but costs is low.
- Full-system diagnostics like other scanners
- Lot of service resets
- Can even do instrument cluster correction
- Free lifetime updates
The Youcanic UCAN-II full-system is second option for go-to scanner. Software seems to be from same provider as for Mucar/Thinkcar so they pretty much will do same stuff. There are also lot of addon options to connect like videoscope or oscilloscope.
- Works well for everything (diagnostics, coding and service)
- Works without internet connection
- Topology scan for some cars
- Free lifetime updates
