Detection is Achieved Using  Stud Detector/ Stud Sensor

1. Magnetic

  • Uses powerful magnets to pinpoint the location of screws or nails in a stud. Therefore it doesn’t detect the stud itself but rather the hardware that attaches the wall material to the stud.

2. Electronic

  • Electronic stud finders rely on sensors that detect changes in the dielectric constant (the relative permittivity) of the wall. This changes when the sensor is over a stud. The lower reading indicates the presence of a stud in the wall and this data is displayed on an LCD screen.

How To Use A Stud Finder

The exact operation will vary by manufacturer, but here is the general procedure:

  • Step 1: Power on the device and choose the scanning mode.
  • Step 2: Place the device flat on the wall. Then press and hold the button while keeping the unit still until calibration is complete (1 – 2 seconds). When calibration is complete, the unit will sound a short beep and the display bars will be cleared.
  • Step 3: While holding on the button, move it along the desired surface to scan.
  • Step 4 : When the stud finder detects an object, it will beep continually and will display on the LCD screen (if available).

How To Choose? Best Stud Finder/ Stud Detector/ Stud Sensor

Buying a stud finder may seem to be a hectic process as different stud finders have different features like some are electric while others are magnetic. The followings are some of the parameters you have to keep in mind to make the best purchase.

  • Frequency – If you happen to use your stud finder regularly and you need it for professional purposes, you should buy a top-quality stud finder so that it can have better detection technology and multiple modes. If you are buying it for the DIY purpose, you can buy a moderate-quality stud finder that does the job good enough.
  • Surface Detection – Depending on what surface you will need to inspect, you need to choose your stud finder. For example, a traditional stud finder can spot studs through walls but some of the advanced ones can detect studs through woods and plastic.
  • The depth of Detection – The depth of the detection matters a lot and even though you will not have an exact idea how deep the stud can be, you would at least have some idea depending on the thickness of the wall or any other surface. You should check the specification to match this requirement.
  • Apart from these – you should ensure that the detection is accurately shown on an LCD screen that most of the stud finders come with. The audible signal should also be strong and instantaneous.

Stud-Finding Tips

  • Don’t touch the wall with either hand while you’re using a stud finder—this can alter its readings.
  •  Some tools need to calibrate before scanning, so start away from switches, outlets, or light fixtures.
  • Apply some painter’s tape over the area you want to scan. It’ll give you a surface on which to mark your findings without having to write on the wall.
  •  When you detect studs, objects, or live wires, mark them.
  •  And where you detect a stud specifically, scan above and below that point to make sure it continues to the floor or ceiling. Other readings, not at regular intervals, could be the wiring, plumbing, or ductwork.
  •  Freshly painted walls may be difficult to scan for up to two to three weeks, due to the moisture in the paint.


Go ahead and buy any of these top 10 best stud finders listed above but you should always keep the parameters in mind to buy a stud finder that can fulfill all your requirements perfectly. Depending on your budget and your preference, you can either buy an electric or a magnetic stud finder.
