Sorting Through the Options: Determining Your Needs
With so many scan tool options available, the key is to narrow down your choices based on your specific needs and the types of vehicles you service.
Vehicle Coverage is Paramount
For shops specializing in certain vehicle types, ensuring comprehensive coverage for those makes is critical. In your case, servicing “2003-present Ford diesels, medium duty Internationals, and medium duty Isuzus,” you need a tool that excels in:
- Ford Diesel Diagnostics: Deep access to Ford Powerstroke diesel systems is essential.

Question: Do I need a different scantool for my class 6 Internationals or my class 4-5 Isuzus than my Fords?
Answer: Potentially, yes. While some high-end scan tools offer broad coverage, the depth of coverage can vary. It’s crucial to verify that the scan tool you choose explicitly lists support for medium-duty International and Isuzu trucks, and ideally, specifies the model years and systems covered. Check manufacturer websites or speak with sales representatives to confirm compatibility. Some scan tools may require optional software or adapters for medium-duty vehicles.
New vs. Used Scan Tools and Software Updates
The appeal of a used, fully loaded Snap-on Versus Pro is understandable due to the potential cost savings. However, the concern about outdated software and updates is valid.
Question: If I buy one used can I update the software indefinitely?
Answer: No, generally not indefinitely. Scan tool manufacturers typically offer software updates via subscription services. When you buy a used tool, it may or may not come with an active subscription.
- Snap-on Update Policy: Snap-on, like other major brands, uses a subscription model for updates. When buying used, you’ll likely need to purchase a new subscription to get the latest software and vehicle coverage. Inquire about the cost of reactivation and update subscriptions for used tools. Also, consider how long Snap-on supports older models with updates. At some point, older hardware may become incompatible with the newest software.
- Other Brands: Update policies vary by manufacturer. Some offer annual subscriptions, while others may have pay-per-update models or different tiers of subscriptions. Clarify the update policy and costs for any scan tool you are considering, especially if buying used.
Recommendation: When considering a used scan tool, factor in the cost of a software update subscription. Compare the total cost (used tool + subscription) to the price of a new tool with an initial subscription period. Sometimes, the peace of mind and warranty of a new tool are worth the extra investment.
