Can you list at least 2 really useful tasks in which double output is really necessary?
The fact that it is necessary for someone, I understand. I would like to hear useful experience.
In what task, faster switching could provide more useful information? What can be lost in a second?
I am engaged in the development and repair of electronic devices. Tasks are found for the second device. And for a dual display, I can’t think of something. Maybe when repairing frequency converters.
I like the BM869s and the dual output capability. Maybe I'll buy it for myself. But I don't see any real benefit.

Very little is really necessary. Most work could probably be done with a single analog meter with low input impedance, accuracy and resolution. A continuity beeper is also not really necessary: you could look at the display. It's just very convenient and makes some tasks much faster.

I find dual display very helpful for looking at DC + ripple (voltage or current) at the same time, and looking at a signal in a system where you aren't sure if it's AC or DC. I had that recently while troubleshooting something powered by an alternator, so it required spinning a wheel to measure. Switching back and forth would have been very inconvenient. Another thing is looking at ACV or ACI and frequency. I was checking an AC signal source and seeing how amplitude and frequency changed under load. Again, switching back and forth while adjusting the load would have been inconvenient.

Sure, this could all have been done with two meters, but that's more precious bench space and more leads to hook up to tight spots. Also, it takes more time to scan two displays with your eyes.

For these reasons I keep at least one meter with dual display around (though not a Brymen in my case). Other meters can be single display for me.

As much as looking at the tiny second display on a single meter?

I bought a Brymen BM869S. World class quality, 5.5 digit, 0.02% class accuracy.
CAT IV 1000V protection. For 220€ new with warranty, case and probe..

New F87V is cca 550-600€+VAT..
Used stuff I don't trust. Not after I saw what people do to them when they didn't buy them with their own money...

And yeah, I don't do Sinophobia..
Or arrogance. There is always someone smarter than me...
What used to be is no more...
