SINCE 2004--Professional Auto Diagnostic Factory

Whether working on cars is a hobby or a cost-driven necessity, most DIYers and backyard mechanics are better off with inexpensive alternatives to expensive professional tools. It’s tough to argue against the usefulness of a Snap-on scan tool, but if you’re just tinkering around for the fun of it, or you’re trying to save some money, then it’s probably better off with a cheaper alternative scan tool.

Although there are some good consumer-grade scan tools and code readers out there, one inexpensive option is to go with a scan tool that can interface with your computer, phone, or tablet. These scan tools rely on the ELM327 programmed microcontroller, and they interface with your computer, phone, or tablet via USB, Wi-Fi, or Bluetooth.
