1 screw or 2 screws?
Sorry, if this has been asked before, but is there any way to deduce how many screws the sound contact has? IMO you can only see number of blades in one screw in DEMON? Is it possible even in RL?
Or do you have to be so close that you could see two different contacts?
Or is it just that operator has to HEAR the difference?
Thx in advance.
