Every time we hear about a diagnostic tool, it seems it will never grow obsolete and doesn’t ever need updating. That might actually be true of a labscope, come to think of it. But at least when it comes to scanners, Snap-on has no plans to foist off such a fib on us.

That’s what happened with nuts and bolts, after all – wrenches had to fit the fasteners at hand!
