Indeed - major kudos to Brymen!  I don’t think many vendors would take that kind of effort.

I just have to ask:  is the expected continuity response still fast?

From my observation, it is indistinguishable from before the modification, in terms of response time.
Some people with better hearing (or faster neurons :P) might notice a difference, though.

Wow, their response surprised me, in a good way. 

The only odd thing is if they provide hack to change hardware components, why the insistence to not allow user firmware upgrade?  It has less risk than swapping out SMD components. 

I like their DMMs, and I would love them even more if they allow user firmware updates. 
Antrus:
The lower the resistance R17, the higher the speed. Right?  The multimeter controller is very similar to the MSP430F.

So FW 08 here and can't replicate the touching anything and it beeps stuff. Metall non metall etc. tried.

Although I am not living in front of some big radar dome or having a big Tesla coil in the flat so might our circumstances differ a bit as others have pointed out. Watching politics sometimes, also doesn't seems to charge things up around me enough to have it detected by the meter.

But the behaviour with some capacitance in circuit sometimes gives false positives that is true, so I am curious how this recomended mod changes that. I hope someone does the mod to test it before me. :)

Also not sure if one can access the parts properly because of the can on the 789 what the 786 doesn't have. Don't have picture in front of me of its guts.
