Scan Tool Compass is an independent research-based resource focused on OBD2 scanners and automotive diagnostic tools.
Our goal is to make technical product differences easier to understand. We organize tools by capability, compare closely related models, explain important diagnostic functions, and highlight both useful features and meaningful limitations.
Our Approach
We use manufacturer documentation, verified product specifications, compatibility information, official marketplace data, and structured comparisons. We do not claim hands-on testing unless we have actually tested the product.
Product prices, availability, software features, and vehicle coverage can change. Readers should confirm critical compatibility details with the manufacturer before purchasing a diagnostic tool for a specific vehicle.
