A carpenter doesn't buy the cheapest hammer, a lumberjack doesn't buy the cheapest chainsaw.
I would love to be with you on this one but this is not what I have seen at least here in Can land. All those guys show up with the bottom of the barrel tools, the best they may carry is Dewalt. As a DYI my tools are better - Hilti, Fein, Milwaukee.
Topic drift alert!
In photography I've observed that prudent professionals invest in equipment which they believe will give them a monetary payback in fairly short order. Hobbyists with means are under no such fiscal constraints, and will sometimes purchase items of beauty to satisfy their lust for gear, even when it would make no business sense. So the very best exotic gear may go to the hobbyists, while prudent working professionals generally use stuff that's very good, but not necessarily the very top of the line.
Furthermore, there are different kinds of professionals. Photojournalists need something that's rugged, dependable, and fast, but resolution beyond what's needed for a newspaper or computer screen is wasted. Nature photographers selling huge prints of beautiful landscapes in art galleries may want superb resolution, but have less need for speed. Those who work in a portrait studio don't need weather resistance nor a wide range of focal lengths, but may value the ability to instantly beam the pictures to a computer for quick viewing on a large screen and quick completion of a sale.
Finally, not all independent professionals make optimal decisions on gear acquisition. The ones who stay in business for a long time at least avoid decisions that would be financially ruinous, though.
Trying to steer myself back toward the Fluke meters topic, a handheld multimeter should be an almost trivial investment for any service professional, compared to the cost of a truck, for example. Dave's video was largely talking about laboratories, military/government institutions, or other types of large institutions. Those customers may value consistency, long product lifetime, traceability, etc. more than the lone independent appliance repairman who comes to a house to diagnose and fix a washing machine. But in my experience, most of the appliance repair people are also using a Fluke, perhaps a 100 series, or maybe a T5 or T6 type tester.
Anyway, the bigger point is that our own individual requirements and values may or may not line up so closely with the criteria used by those who chose a Fluke.
