Factors to Consider when Choosing the Best OBD2 Scanners under 100
Here are the key factors to consider when choosing the best OBD2 scanner under 100.
Compatibility
Compatibility is the first thing to consider. The scanner should support a wide range of vehicle makes and models, especially those manufactured after 1996, which is when OBD2 became standard in the U.S. Checking for compatibility with your specific vehicle brand and model will prevent future frustrations.
Type of Scanner
Next, consider the type of scanner. Some scanners offer basic code reading and clearing functions, while others may provide more advanced features like live data streaming, freeze frame data, and emissions testing. While staying within a $100 budget, it’s possible to find scanners that strike a good balance between affordability and functionality.
Ease of Use
Ease of use is another important factor. The user interface should be intuitive, whether it’s on a handheld device or through a mobile app. The best OBD2 scanners under 100 have clear displays, simple navigation, and easy-to-understand diagnostics.
