Guide To Using A Straight-Line Stud Finder
Before we learn how to use a straight-line stud finder, it’s good to know the available types. They include the following:
- Magnetic Stud Finders
As the name suggests, magnetic stud finders have magnets in them. They help find a stud by getting stuck on the part of the drywall that has a screw in it. It is assumed or expected that screws connect the drywall to the studs.
- Stud Finder App On Phone
There are stud finding apps that you can download on a smartphone. They work by detecting screws using your phone’s magnetometer, a sensor that measures the magnetic field.
- Electronic Straight Line Stud Finder
Electronic stud finders require batteries to operate. They pick up the denser parts of the drywall. In this post, we shall discuss how this type of electronic finder works.

Making The Most Of Your Stud Finder
As with any other tool, you will not achieve your desired results if you don't use it correctly. Therefore we have provided tips on how to use a stud finder for maximum benefit:
- Don't turn the stud finder from one side to the other while looking for studs. Instead, keep it upright and flat against the drywall.
- Neither of your hands should be on the wall. Instead, ensure you are holding the stud finder firmly against the wall.
- Stud finders work best on drywalls and not on plastered walls.
- If you didn't know, you can also use your stud finder to locate joists on the ceiling.
- Don’t forget to mark the areas you have found to have studs, or you might forget where the studs are.
- As a guide, studs on walls are normally 16 inches apart, and 24 inches apart in ceilings.
- Don’t forget to have with you an extra pair of batteries. Your gadget can suddenly stop working simply because the batteries are dying.
How To Troubleshoot Your Electronic Stud Finder
As simple as the stud finder looks, it can malfunction because of several reasons. Below are some solutions to problems you may experience with your stud finder and how to troubleshoot:
Examine The Battery
This should be the first step to finding out why your stud finder is not working. It could be your battery has expired, or you are using batteries that do not last long.
Calibrate Your Stud Finder
Your stud finder can malfunction if you press the calibration button before placing it on the wall. If you do this, the stud finder will set itself to locate the density of thin air, instead of the dense parts of the wall.
To correct this issue, place your gadget on the wall, and press the button. It will calibrate so that it can pick out the studs.
Edge Finder Vs Center Finder
If you did not determine your stud finder before using it, you could get some errors. Find out if yours locates the edges or centers of the studs. You may end up marking the edge of a stud when in fact it is the center of the stud.
Pros And Cons Of An Electronic Stud Finder?
Let’s look at the Pros and Cons of the electronic stud finder vis-à-vis the magnetic stud finder.
Electronic Stud Finder
- Offers more precision at identifying studs than magnetic stud finders. The light illuminates precisely on the edges of a stud or the center of a stud.
- The highest quality electronic stud finders can find studs through walls up to 1.5 inches deep. A magnetic stud finder cannot reach such depths.
- There is the risk of the gadget not working because the batteries are dying. On the other hand, you can use a magnetic stud finder without batteries, meaning you do not have to worry that your gadget may fail mid-way.
- Electronic stud finders are typically more expensive than magnetic ones.
Magnetic Stud Finder

- Small enough to carry around, including in your shirt pocket.
- Don’t require batteries to function.
- They are less expensive than electronic stud finders.
- Since they detect metal, they not only pick out the screws in the studs but can also sense where nails on a horizontal board are. This can be a costly error if you drill any other part of the drywall, and not on a stud. This can be hazardous, especially when hanging something heavy like a painting or installing a shelf. The strain of the weight on the drywall can damage it.
Is It Necessary To Use A Stud Finder?
If you don’t have a stud finder, you can still use other traditional methods which may not be worth it. For example, you can tap the drywall, and listen out for sounds. The area that produces a solid sound has studs behind the wall. Or you can use a flashlight to check for dimples, which indicate the studs are there.
These methods are not exactly reliable, though there are experts who can use them and find the studs.
However, it's good to avoid making any mistakes, or you might mess up big time. For example, if you hang a heavy painting on your drywall instead of on a stud, the screws can fall out slowly due to the weight. Eventually, the painting may fall, damaging it.
An electronic straight-line stud finder is an essential gadget that is necessary to have in your home. Correctly using a stud finder is the only way to make the most out of it, and if it stops working, you can troubleshoot using the methods discussed herein.
