• Weight: 1.3 lb
• Screen Size: 3.5 in

Best for: Bidirectional repair workflows.

Why it ranks #1: Combines OBD2 and OEM live data, ABS and SRS code access, oil-light reset, battery checks, and a 3.5-inch screen.

Bidirectional control gives the Innova 5610 a repair-oriented edge, allowing users to interact with supported vehicle components rather than only read codes. Its 3.5-inch screen and access to OBD2 and OEM live data support a more detailed diagnostic workflow, while included pouch and protective boot help with tool handling and storage.
