Question about Stanley Measuring Tools & Sensors
Most stud finders have a sensitivity adjustment that should be carefully adjusted per instruction manual before use.
Failure to do this results in erroneous indications.
If you have adjusted exactly per the instructions with the same result the unit is probably faulty.

SOURCE: I have a Stanley stud
The 77-110 does not detect electrical wiring. The model 77-720 model does detect electrical wiring but not the 77-110. You must first place the stud finder against the wall, press the button and wait for the light and audio signal to stop. Once this happens the unit is calibrated and while still holding the button down, you then move it across the wall to find the studs. Problem is that this unit is very unreliable and does not work as advertised most of the time. It has a lifetime warranty so my advice is to take it back and get a refund if possible. I have tried many stud finders an most are not reliable and cannot be depended on 100% of the time and this Stanley is one of the worst. The best inexpensive stud finder I have found is the Gardner Bender stud seeker at around $12.

Your stud finder keeps beeping because old plaster walls have lath boards behind the plaster that are attached to the studs and running horizontally. Try adjusting the sensitivity of the stud finder by placing it on the wall and turning the sensitivity down until it just stops beeping. Then move it back and forth in a wide enough arc to be sure that you have crossed a stud, turning up the sensitivity ever so slightly until you get a tone when you cross a stud. Hope this works out for you.

Without knowing what room you are using it in it could be a underlayment of wire mesh that you are reading. If it is an older home this was used often as a backing for plaster instead of lath.Thank you.
