Stud finder

In my room I do not have traditional sheet rock on my walls a have a type of wood panelling. I know how to find studs in sheet rock but I was not sure how to find them with the wood panelling I have in my room. So my mentor let me borrow this stud finder and tonight I am going to see if I can find a stud around where I want to put the tv mount. The stud finder seems pretty simple to use so I do not think that it should be too hard to find one.
