I use two BM789 in my work.

Often and a lot.

And, from your perspective, don't the spurious beeps significantly slow down your tracing process (i.e. making the experience similar to using a slow continuity response meter)?
Or it does, and you just learned to accept it?

I tried to reproduce with my 789, firmware 78911 but no luck.   I tried with a single lead to various equipment, a large plate and sheet of foil.  Then tried both leads with foil, plate and other metal equipment.  I never had it trigger.   Foil sheets and plate were about 2' sq and floating.   Equipment I was touching off on is all grounded to earth.   Meter sitting on grounded ESD mat.   
Electro Fan:
78905 produces random continuity beeps.
NoisyBoy:
No issue with 786.

I wonder if it is firmware version related. 

Not that it matters since Bremen will not provide end user firmware upgrade. But at least it may help for those who are shopping for a used 789 if it is firmware related.
