I read the first link and did not see an answer to the OP's question. I saw a definition of stud finders, features of some stud finders, and not a specific recommendation for any particular one.
I'm looking for a better than good studfinder.
Feedback is appreciated
I see that as asking what stud finders each of us find exceptional, not asking for a definition.
The poster's brevity indicates to me that a brief answer is appreciated.
If you wish to provide links to generalized material, perhaps you could also quote the pertinent sentence or two that prompted you to think the link was helpful? In the forum rules thread
(HERE), members are asked to explain why a link is useful to the conversation. This aids the conversation greatly, and adds context to the link.
If you would like to discuss this further, feel free to shoot me a private message.
