Electronic stud finders work by comparing two things. Everybody knows materials can support a static electric field to a certain degree. Air is better than copper (copper flows electricity but air will prevent electricity from flowing (it insulates). So stud finders compare how well two materials insulate (typically the air-drywall combination versus the stud-drywall combination). The stud finder is basically a metal plate and a capacitor (a thing that stores up an electric charge). The stud finder compares the electrostatic charge stored in the capacitor (the calibration result in the initial air-drywall calibration) to whatever else is there as it rolls along the surface by using the plate. When it detects a difference from the stored charge in the capacitor then it signals the change, first by the bottom red light then the top red light and a beep.
Ok, so if you get the theory then any kind change in the electric charge-storing ability of the material (strictly any change in capacitance property of the material) will trigger a beep and a red light. This is a shortcoming of all electronic stud finders not just the 77-110. How accurate the stud finder is in locating the center of the stud depends on the plate configuration, the geometry of the field it broadcasts and the change detection electronics.Read more ›
* Ran it across about a dozen walls and it worked perfectly - getting the edges of studs without fail. I tested the results with a thin wire nail at a few places and it was consistently getting the same results
* Today - 3 weeks later - I take it out of my toolbox - and the thing won't measure worth a darn ANYWHERE. I initially thought a wire may be messing up the scans - so I tried it on several walls. Every wall I tested all of the sudden has studs that are six inches wide on edge now.
Total piece of garbage. I am very disappointed in this product b/c I actually had great results with it - but that only lasted for one useage - and it was gently placed in my basement toolbox. I guess they are disposeable.
* One more con against this unit is the 9 volt battery connection. It has the 2 wires that snap onto terminals. It grabbed the batteries so tight that it ripped one of the connectors off my battery. I prefer the ones that slide the 9 - volt battery into place.
Definitely NOT recommended -
Running it over wallboard was useless, since it never located the same stud twice. On one pass it beeped for a stud & on the next pass the stud had suddenly disappeared. The only thing consistant with this stud finder was its inconsistency in finding studs.
Luckily, it soon fell out of my pocket into a bucket of paint, which solved my problem. Now I have better luck finding studs by tapping the wallboard & driving in a thin nail where it sounds solid. Actually, my problems are not completely solved, since I still have to put up the shelves.

Does not work at all. When calibrating, every single wall in my house makes the AC Current alarm go off. Even our doors show an AC Current. Read morePublished 22 days ago by Amazon Customer
Beeps for electrical in walls too, but most all the time (which I believe is false for wiring).Published 3 months ago by RM
Used this once to try to begin the process of hanging my tv on the wall. It kept showing my studs are 6" apart no matter what I did. Read morePublished 6 months ago by Rustybear
Please save yourself the headache of owning this infuriating device. It thinks the entire wall is "stud". I even tried adjusting it with instructions from Youtube. Read morePublished 7 months ago by Amazon Customer
Big waste of money. Inconsistent. Runs the battery ... I'm better off knocking on the wall to find a stud. Read morePublished 8 months ago by A. Rush
