Best Stud Finders Buying Guide
Before diving into features and functions, you should determine what kind of stud finder you would need. In order to figure that out, you’ll need to assess your own needs. How often will you be using it and how important is accuracy for you? Are you an experienced DIY-er or just a beginner with an appliance to mount? Once you have your own prerequisites, navigating features, functions, and types becomes a breeze.
What Different Types of Stud Finders Are There?
There are three main types of stud finders ranging from the low tech to the high tech and high price.
Magnetic stud finders
A magnetic stud finder works through a powerful neodymium magnet that is able to detect nails or screws in the stud. More powerful magnets have made this option more and more accurate while the price remains reasonably inexpensive. A magnetic stud finder is very useful for detecting the location of metal drywall screws or nails.
It’s an excellent choice if you’re just looking to use your stud finder once in a blue moon and don’t want to invest in an electronic one. If you have the patience, it might even be a good long-term solution. However, keep in mind that if you’re a complete beginner, a Youtube tutorial will go a long way when it comes to getting the most out of this tool.
Electronic stud finders
Electronic stud finders are currently the most popular option as they’re very beginner-friendly and quite accurate. Powered mostly by two AA batteries, these stud finders usually do more than just find the stud and locate its center. Most have additional detection for AC wiring and piping, as well as wood and metal detection. Some electronic stud finders also come with an LCD screen for a better user experience.
These work by detecting density changes in the wall and they run a bit pricier than their magnetic counterparts. However, we were able to easily find something in the $20 to $30 price range that will work well for years to come. If you find that ease of use and additional detection are good selling points, this is the stud finder for you.
Ultrasonic stud finders
This is the priciest option of the bunch and for good reason. They use sound waves to determine what’s in the wall and they’re usually used in a construction environment rather than for home projects. If you’re serious about your DIY projects or you work in the construction business, this might be the ideal gadget for you.
Other Features and Considerations
Calibration
Most metal stud finders (electronic ones included) will need to be calibrated before use. In fact, this is one of the reasons why so many people end up returning their stud finders, throwing their arms in the air, and declaring that the gadget was inaccurate.
Reading the instructions on how to properly calibrate your stud finder will make a huge difference. Also, it will likely be the determining factor in whether your experience is successful or not. Of course, there are many such tools that simply lack the accuracy needed even for home projects. But, most of the time, reading the manual and the troubleshooting instructions will take little time but make a huge difference. As the normal process goes, place the stud finder flat against the wall, press and hold the power button, and wait for 1-2 seconds before calibration starts.
AC wires detection
This is one of those features that you don’t care about until you do. Most electronic models will have AC wires detection feature and it’s something to consider if you think that there are any home improvement projects in your future where drilling or mounting appliances or cabinets risks hitting live electrical wires.
Pipe detection
Another common feature for electrical stud finders is one that you’ll want to take into account the more projects you do. The device will usually have a different function or LED color to let you know if you’re in an area near a pipe.
Sensor depth capacity
The depth at which your stud finder is used to detect is important. A good one should be able to detect at least 1.5 inches into your drywall and probably a bit deeper if you need to be able to spot copper pipe wiring or metal pipes.
Center targeting
Another great feature to watch out for is center targeting. While finding a stud can be enough, the best stud finder will also let you know when you’ve identified the center of a stud, which can save you a lot of time and calculations. Make sure to recalibrate and follow the manufacturer’s instructions if you plan on using this feature.
How To Use a Stud Finder
Once you select a product of your choice and purchase it, you will need to know the ways to use it.
- Turn on the power button of the stud finder.
- Once you see the green light indicator, the stud finder is ready. Ready lights indicate that calibration is successful.
- The red arrow lights up sequentially as the stud finder nears a target.
- Position the stud finder against the wall, before starting to drill the wall in one direction.

People Also Asked
How does a stud finder work?
The first stud finders worked by using magnets to detect nails or other ferrous materials. Newer models work by detecting differences in the density of the material behind the wall.
How do you tell if you hit a stud?
The best way to identify whether you’ve hit a stud is the old fashioned way - by knocking. A solid sound will mean that there is a stud behind the drywall while a more hollow one means no stud.
Can my phone find studs?
There are some apps that use the phone's built-in magnetometer to locate metals in the wall however these won’t be as strong and won’t be able to read as deep as a dedicated tool like a stud finder.
Do stud finders really work?
Yes, stud finders work. However, in order to ensure precision you will need a good stud finder and a bit of knowledge on how to operate it. If you go for a magnetic or low tech option, you should spend a few minutes making sure you’ve got the hang of using it. If you’re going for a wall scanner, you should be good to go after an initial calibration.
