Stud Finder Buyer’s Guide

Types of Stud Finder

Basically, there are two main types of stud finders that you can find in the market, classified by the methods they use to locate the studs in any building.

These two types of stud detectors are electronic stud finders and magnetic stud finders, and both of them have some advantages and disadvantages that are worth bearing in mind.

Magnetic stud finders use highly powerful magnets, usually neodymium, to find the metal screws, which are used to hold the stud in place.

This means that they can be a little less detailed than electronic stud finders, but the lack of electronic components makes them more reliable and durable, and less likely to give false detection.

The magnets also have a limit on how far they can detect metals so deeper studs may not register nice on magnetic stud finders.

The huge difference, though, is that the best quality magnetic stud finder tends to be cheaper than a decent electronic stud finder, so if the cost is an aspect in your decision making, you are likely to choose a magnetic stud finder.

Meanwhile, electronic stud finders, work through a system of sensors that can detect any changes in the electrical conductivity in the wall.

This means that the areas of different density and conductivity in the wall, like studs, are detected, bringing up reading on your LCD screen.

Often they can penetrate into the wall than a magnetic stud finder is able to achieve but this comes at the cost of consistency.

Many cheap models of electronic stud finders are susceptible to false positives, and the electronic systems are much fragile and easily damaged than magnetic stud finders are. Electronic stud finders are able to detect other features in your walls and they are more versatile than their magnetic counterparts in a lot of situations.

Stud location

In so many cases, you are going to be looking for studs in your building’s walls. If this is the case, then pretty much any stud finder can do the job, as they are designed for use on walls. In some cases, though, you will have to look for studs in either the ceiling or floor of your building. If this is the case, you may need a more advanced stud finder. Floor studs can be hidden deeper under the surface, and more basic stud finders may not have the power to detect deep studs on the floor.

For this, you will require something more powerful that usually comes at a high price. It is also worth seeing the grip on your chosen stud detector, as looking for studs in the floor or ceiling often requires holding your tool at a different angle, which can be uncomfortable unless your stud finder has been intended for a comfortable grip at different angles.

Types of Stud

Studs in walls can be made from a wide range of various materials, and certain stud finders are calibrated only for finding precise types of studs. This means that being aware of the type of stud you are finding will make the calibration and location process much easier. Many walls of the home are made of wooden studs in the walls, but many commercial buildings have heavier duty metal studs. In some cases, buildings may have plastic studs built in the walls which are very rarer and therefore less likely to be supported by the technology of detection used in any stud finder tool.

Other Ways to Find Studs

In addition to electronic and magnetic stud finders, there is an old fashioned method that you can try for stud detection. It is not always going to be accurate and will not work on each and every wall, but it might be your best option if your stud finders are not working properly. If you rap your protuberance against the wall, it will make a hollow tapping sound. When you tap just over a stud, the sound changes to a solid noise, which can a sign of indication of where the studs in your wall are located.

You can also use electrical sockets as a rough guide. Usually, the sockets are placed next to studs and tend to be more predictable than you may think. As many people are right-handed, the majority of electrical sockets are situated to the right of a stud other than the left.

This means that you can find a stud simply to the left of an electrical socket. That being said, not every electrician is right-handed, so this is not a reliable method, as you always have a risk of finding a socket that has been installed by a left-handed electrician.

Expert Tip

You might think a stud finder is not a vital tool, but you could be wrong. The construction of walls is a complex and precise system, and you do not want to drill into the wrong part of the wall.

Did you know?

The walls in older houses are often thicker, with studs sunk deep behind the wall. This means that the older your house is, the best quality stud finder you will need for getting good results.

What to Look for in a Stud Finder

Stud material

 Many houses have wooden studs, but commercial buildings might have metal studs and there are instances when plastic studs are used. Certain stud finders can only find one type, so take the stud material into account before purchasing your best stud finder.

Stud location

You want to ponder whether you are looking for studs in a ceiling, wall, or floor, some basic stud finders may not be strong enough to penetrate through a thick floor. Also, you will want to ensure that your tool has a best and comfortable grip which allows you to hold it at any angle.

Additional features

You might want a basic tool that finds studs and not anything else. Anyhow some high-end models have extra features that can be helpful for complex projects. For instance, some units can detect wires or even keep a map of the wall that you are examining helpful information for greater tasks.


How Do Stud Finders Work?

A magnetic stud finder works without any batteries. It uses a rare-earth magnet. It does not actually detect studs but locates the screws or nails that are attached to the wood. It’s a little time consuming to operate since you are hunting for metal fasteners and does not work very well on the walls of older buildings where a deeper scan is required. Conversely, an electronic stud finder contains electronic components with the ability to use sensors to assist you in finding the actual location of studs. Moreover, such electronic devices come up with LED lights and audible tones to notify you the moment the edge of a stud is spotted. Their greatest negative is that they need a 9-volt battery which can provide bad results if not replaced regularly

What does a stud finder detect?

A stud finder is used to detect framing studs that are placed behind the surface of the wall, typically drywall. Sometimes it depends on detecting the metal in the studs to find them. A few models are very useful on ceilings and floors.

Why false positives are common when using a stud finder?

Usually, it is a variety of reasons. Sometimes builders rush and studs in walls totally are not straight or have little shifted over time. Sometimes the drywall has small bubbles that may obstruct with a stud finder. With electronic models, batteries that are drained can give bad results.
