Resolution and accuracy are two very different things. Digital mics often have so many digits after the decimal point that it is difficult to keep track of what you are reading. That is resolution, how many digits it READS to. Do not be disillusioned into thinking that is the ACCURACY of the mic. The accuracy is only usually shown in the documentation, not on the mic itself, and is much lower. If you are not working in a clean room with climate control, parts and tools soaked to ambient, tools regularly calibrated, and no touching parts or tools with bare hands, anything beyond .0001" is sheer salesmanship, and while it has some limited value in comparative measurements, it is just window dressing in a H-M shop.
The HF caliper I use every day in the shop has a RESOLUTION of .0005". It's accuracy depends on how and where it is used. Techniques play into the equation. I have no idea what the maximum ACCURACY is, because I don't really use it that way. I am only using it as a modern, $10, easy to read substitute for this:
And it works just fine.
I have no electronic mics. I am not excited about throwing the expensive things away when they fail, and they will fail. Not excited about dead batteries, either. Not at all excited about the bulkiness of electronic mics. If I used mics all day every day, or in a tool room, my preferences might change.
Finally, I am not a fan of AvE, either. Dropped my subscription long ago. I consider it a dog and pony show, playing to the audience but irreverent to all. Entertainment, and I tired of it quickly. YMMV. His ~100,000 subscribers do...
