Why Do A Diagnostic Reading?

Buying A Diagnostic Computer Is Expensive - Laptops and software for diagnostic readers will cost you upwards of $10,000 if you wish to buy the equipment and do all the work yourself. However, asking us to complete the reading with our equipment will cost you a fraction of that.

Perfect Troubleshooting - While mechanics and engineers are great, everyone makes mistakes. Instead of 'assuming' what maintenance your marine equipment needs, using our diagnostic reader will alert you to the exact problems that need addressing. 

Saves Money - A long time ago, diagnostics were completed based on assumptions and knowledge of the mechanic. Now, we can diagnose everything to and find out exactly what needs to be serviced on your vehicle, ultimately saving you both time and money.

Top Of The Line - General diagnostic scans won't tell you what is actually wrong with your vehicle. Our software can. Our readings will be the most in-depth and give you access to never before seen information you needed to know including live data and technical service information.
