Best Stud Detector for Electricians– Top 5 Stud Finders

Although we generally believe that stud detectors are majorly for electricians, the tool has proven indispensable in homes.

Do-it-yourself homeowners often get the device to locate studs quickly in their walls. Thus, they can hang their items such as a picture frame, mirrors, and a flat-screen TV on the drywall without fear of falling off.

This is particularly important because the build of the drywall is such that hanging heavy items on it can lead to its crash.

Stud detectors might be seen as excessive accessories, but they are significant in understanding the layout of walls and preventing dangerous mistakes.

Notably, the best stud finders possess features that assist users in other ways than locating the exact spot for hammering. These features are LCD screens, spirit levels, and detectors of a live wire.

While using stud finders, you should always keep certain things in mind for accurate results. First, you should not touch the wall with your hands as you drag the tool over the border to prevent altered readings. In addition, you can put painter’s tape around the area you want to scan to help you get your findings without writing on the wall.

Lastly, when locating a stud, you should check the top and the bottom of the spot to ensure it continues to the ground or up to the ceiling. This is because stud finders might sometimes detect metals or nails.

With all that being said, we’ll explore the top five stud detectors for electricians in this article. In the end, you should have a fairly good idea of what would work best for you.

How to find studs in wall?

To find studs in a UK wall, you can use these methods:

  1. Tap on the wall and listen for solid sounds indicating a stud.
  2. Use an electronic or magnetic stud finder to detect studs.
  3. Inspect the baseboard for nails or screws that may be fixed into studs.
  4. Check around outlets and switches, which are commonly mounted to one side of a stud.
  5. Slide a magnet along the wall to find nails or screws in the studs.
  6. Measure 16 or 24 inches from a corner to find standard stud spacing.
  7. Look for wall indentations that may signal stud locations.
  8. Peek inside a removed outlet or switch cover to possibly see a stud.
  9. Drill a small hole to probe for a stud, but be cautious of wires and plumbing.

Things to Consider Before Buying a Stud Detector

Before you place your order for your stud detector, either the regular stud finder or other stud finders, there are certain things you should look out for to prevent future regrets. 

Although we listed the five best stud finders in this list, we also put together this guide for people who want to choose a brand themselves. This way, they can pick their tools rightly and easily. Below are the criteria a good stud finder requires.

Category of Stud Detector

We’ll have you know that there are two categories of stud finders which are electronic and magnetic stud finders. The magnetic finders possess rare earth magnets for detecting the accessible location of drywall screws that hold the drywall in place. In addition, most of these magnetic stud detectors are light with powerful magnets. While using this tool, you must move it in a sweeping motion to detect studs quickly.

The other stud detector is the electronic one which utilises internal sensors to point out the wood studs. Significantly, these tools notice a change in the density of the space behind the wall. Most of the top electronic stud finders are usually pre-calibrated. To use an electronic stud finder, it is best to move it in a horizontal motion over the wall. Then, when it discovers studs, it will release a loud alarm. Electricians prefer to use electronic stud detectors as they do not detect all metal objects like magnetic ones.

Quantity of Sensors

Although electronic stud detectors were invented in the 1990s, they have grown to become highly sought-after in the construction market. You should remember that an electric stud finder uses sensors to determine the location of studs in a wall. Hence, if a finder has one sensor, it can only detect a stud’s edge, while one with multiple sensors finds it very easy to see the stud edges and the stud’s centre. While both stud finders with single and multiple sensors are reasonable, if you need a great deal of accuracy to get your job done, you should choose a stud detector with multiple sensors.

Size of Stud Sensor

While looking for a stud finder to purchase, you should also check the stud sensor size. Stud detectors usually come with large or small sensors, each having advantages. Thus, you should choose the one that best meets your requirements. Stud detectors with large sensors can check large areas and penetrate solid walls. On the other hand, stud finders with small sensors usually give more accurate results. If you are a do-it-yourself homeowner, you don’t need to choose a specific sensor size as both work efficiently in pinpointing the location of studs in drywall. As a professional electrician, you might want to go for something with smaller sensors and more specific readings. 

Depth Adjustment

Another factor you should look out for before buying your stud detector is if it has a depth adjustment. This is for a deep scan or simple wall tests. It would help if you always remembered that only electronic models have this feature.

Brand Reputation

Some people might not recognise the effects of brand reputation on the efficiency of a product, but we have come to know this fact, and it should guide you in selecting the best. A company with a solid reputation must have done specific things to achieve that. With this in mind, you should only choose brands that are already well-known for offering top-notch tools.


Another criterion you should check for is the durability of the tools you’re interested in. Specifically, you want to look out for the general make-up, material, and battery life of electronic stud detectors. If the brand uses robust plastic and high-quality rubber mouldings, that’s usually a good sign. With regards to batteries, you want a product that has or supports high quality batteries like Duracell.


Most times, the price of stud detectors depends on the product’s function and your budget. If you want to go for a magnetic stud finder with easy duties, you won’t have to pay as much as when you purchase the tool with more features. Thus, you should buy a brand’s product within your budget.

Frequently Asked Questions

Can I use stud finders on ceramic tiles?

Electronic stud detectors are not very good at finding studs on ceramic tiles. However, these unique stud detectors are able to work much more effectively when they’re built with a deep mode feature. As such, if you’ll be working with a wide range of surfaces, you’ll likely want to get one that comes with this feature. The chances are that it won’t work on every single surface as no product is that perfect. But, it will certainly increase your chances of getting the job done.

What’s the standard distance between wall studs?

Using the on-centre method, wall studs are usually 16 inches apart. That is, the centre of a stud will be 16 inches from the centre of the former. However, there are other acceptable measurements and, because of them, a stud can have a 19.2-inch or 24-inch distance from the centre for the previous and next ones.

When my stud finder beeps, what does it mean?

There are diverse stud finders, each having distinct features. As a result, the signal that each tool emits depends on the device that is bought. While some of these stud detectors give the beeping sound when they notice a nearby stud, some also beep when they see the centre of the stud. Therefore, you should study the instruction manual that comes with the tool to know what each beep signals.


While we tested a variety of stud finders before we picked these five, we ensured that they met all the factors we judged them by. In addition, trying these products was enjoyable as we could discover certain uniqueness that each possessed.

Thus, if you have been looking for the best stud finder for your work or home decoration, you should read through the article to pick one.

Furthermore, while we did our research, we learned that electronic stud detectors were the most recommended for electricians and do-it-yourself homeowners. The electronic stud finders rely on sensors to accurately detect wood and metal studs.

The stud finder quickly detects where to fix mirror mounts and other items too heavy to get hung on the drywall itself—getting the studs enabled people to fix their things without fearing it falling off or the wall crashing down.

However, if you have checked through our list and want to do more research on these brands, you should go through the buying guide to note what to check out in each product.

Specifically, you should ensure that you purchase tools from industries with a good reputation in the construction market. It is preferable to get tools from these places as they have already received recommendations from numerous people who have tested their efficiency.

Overall, endeavour to place your order for these tools online as it is more trustworthy to get from the company directly than through intermediaries.
