5 Best Stud Detectors for Plaster Walls
Author: Reece Thompson | Updated on February 25, 2021
We've installed hundreds of drywalls and know the most reliable tools. With a reliable stud finder, you can accurately locate timber framing behind a wall. We review five of the best ones.
In the refurbishments and renovations we've done over the last eight years, we've put up over 200 stud walls.
Most of these have gone to plan, and we've gotten good at it.
In the early days, we weren't good at drilling into walls, i.e., once they'd been plaster skim finished and painted over.
Whether it was stubbornness - or being too cheap - we were poor at drilling in wall furniture. We'd end up having to use filler to tidy up all the erroneous holes!
For example, the final touch in the bathroom is to install a toilet roll holder or a towel holder. It would be stress-free to use a stud detector to locate the timber frame position and drill into that. But no, we were too cheap to buy one!
These days, we always use a stud finder BEFORE drilling.
Without a good stud finder sensor, the whole process becomes disorderly and messy. This is why a high-performance stud detector is crucial for DIY projects.
How to Pick the Best Stud Finder?
If you've never used stud finders, choosing one can be tricky. There are so many types and plenty of knock-offs from China.
At first, you need to examine the surface beneath which you are trying to locate a stud. This will allow you to pick the type of stud sensor that will suit the task.
They come in two different types: Magnetic stud and Electric. The magnetic detectors do not locate the stud but the hardware that attaches itself to the wall. But, electric detectors use sensors to reveal the relative permittivity of the wall.
When you move the stud finder over a stud, it is indicated on the device's LED screen.

What Are the Benefits of a Stud Detector?
Some DIY enthusiasts can find a stud behind a wall by tapping and listening to the sounds; it isn't easy for others.
A stud finder will help to detect studs by placing it against the wall.
Some detectors are versatile as they help to locate not only timber but also electric wires or pipes. I wish I knew that before I drilled a hole in the wall one time, cutting an electric wire!
How to Use a Stud Finder?
The correct way to use a stud sensor locator is based on the exact model and type.
But here's a rundown on general tips to use one.
At first, you must calibrate your stud finder and place it against the wall behind. Turn on the device and press the side buttons. Next, slide the stud detector across the plaster wall until the machine sends an alert.
Then, mark the stud's location with a pencil. You may choose to repeat the steps a few times to ensure accuracy.
You may want to watch the explanatory video if you'd like a better understanding of the process.
The StudBuddy is one of the simplest ones of its kind out there. It uses strong neodymium magnets to detect wood and metal. It works great with both drywalls and newer plaster walls. You could even use it for ceilings.
The device has built-in plumb and hangs on the wall hands-free when stud findings arise.
Besides, it has smooth pads on the back that prevents any damage using it as a wall scanner.
This one is ideal for people who are in search of simple tools to get their job done.
Promotes visual reference while hanging objects
No batteries required
Not functional for metal or electric wires
How We Decided On Our Winner
From the reviews of the detectors above, you can understand how each one has an advantage towards a specific type of surface or material. Yet, we have concluded that Zircon MultiScanner i700 is the winner.
It's the solution to the detection of studs made of various materials, all that is not supported by the other finders.
When it comes to detection through the thickest walls, the Zircon ensures the most accurate results.
That being said, we reviewed a lot to come down to these 5 options. All of them are reliable tools for specific requirements.
Thus, you must select one based on its capabilities, accuracy, price, and preference.
FAQ and Buying Guide
When buying a new home, one of the ways to try and create added value is to create extra rooms. Yet, you can't start knocking down walls and building new ones back up.
You need to check stud behind drywalls to see if there are any plumbing or electrical concerns. You don't want to start drilling to hit a water pipe(!)
By using a stud wall detector, you can:
Locate material edges Detect wood, metal, ac live wire and deep modes
You don't have to be a home buyer like us. These devices are perfect for plumbers, joiners, home renovators and so on.
How do we use it? We create more rooms! Using these tools, we assess this quickly in two ways:
Adding value to the property by installing a wall in large rooms Determining which walls are stud so that we can take it down
The first option is self-explanatory and doesn't need much discussion here.
The only electrical tool you'll need here is a digital measuring tape to get your sizing accurate. And yes, a standard old school measuring tape will suffice.
For the second way, you'll need to invest in stud finders for walls.
Before knocking down any walls, you'll need to know where the wooden battens are. This is important as you don't want to be smashing your sledgehammer into water pipes or AC wiring.
Advanced finders will be able to detect metal, electrical wiring, central heating pipes also to timber.
We have used all the ones above and feel like we're in a good position to state which ones hit the mark.
