The Matco Tools maxME bi-directional scan tool features a patented, pay-as-you-go software subscription service. Designed to be both affordable and customizable, the maxME allows users to only pay for the car makes they work on. Subscriptions start as low as $20 a month and are offered by car make, region (domestic, European or Asian) or one that covers everything. At any time, users can add, delete or update makes, right from the tablet’s screen. In addition to being an advanced diagnostic tool, it’s also a full-featured, personal tablet. Troubleshoot engine codes, stream music and play apps — all from one tool. The Android-based device is dust-proof, drop-proof and waterproof.
