Stud Finder Buyer’s Guide
Most stud finders, also known as stud detectors, cable detectors, wire detectors or wall scanners, have the ability to detect a range of material located within your walls. This can ensure you find secure studs for fixing items like shelves, TVs, mirrors and cabinets. Most stud detectors also alert you to the presence of metal and live wires in your walls, thus preventing you from accidentally drilling into electric wires or gas and water pipes.
Stud detectors do vary in the depth they can scan but most scan to an adequate depth for allowing you to fix items to walls safely.
Stud detectors, wire detectors and cable detectors sometimes have an auto-calibration feature which makes them foolproof to use. Other models require you to calibrate them by holding them against the wall and pressing a calibration button then keeping the product in the same place until a beep or sign on the screen tells you that calibration is complete. Many stud finders have to be recalibrated before every use.
Stud finders generally have clear LCD screens which are easy to read. Many also have backlit screens which is useful if you are working in badly lit areas.
What is a stud finder?
A stud finder is a small, handheld device that can be used to detect items that are hidden behind plaster or plasterboard or above ceilings or under floors. More advanced scanners, such as the ones in this review, have multiple modes that detect studs, live AC wiring, non-ferrous metal (such as copper pipe) and ferrous metal (such as steel reinforcement bars).
How does a stud finder work?
Electronic stud finders and cable detectors have sensors that measure changes in the dielectric constant of the wall. Wood and metal studs have a much higher dielectric constant than the voids of air filling the area between the studs and have a greater influence on the electric field. The stud finder measures these changes and display the results on an LCD screen.
In addition, modern stud finders can also detect the presence of live wires. These wire detectors contain sensors that act as a receiver which can detect 50/60-Hz. Again, the presence of this current, and therefore live wires, is indicated on a screen and some models also give an audible warning of the presence of live wires.
Modern stud finders also contain an inductive sensor which generates a magnetic field in order to detect metal. The magnetic field is boosted in the presence of ferrous metal and deformed in the presence of nonferrous metal. Again, the results are analysed and reported on the metal detector’s LCD screen.
How deep can a stud finder scan?
In general, a stud finder can detect wood or metal studs to a depth of up to 38mm. The scanner can also detect live wires up to a depth of 50- 60 mm. The actual depth a stud finders can detect will depend on the technology used in each particular model so you should check your user guide.
How do I use a stud finder?
Most stud finders require calibration before use. To do this, you hold the scanner against the wall and press the calibration button. The machine will usually beep to let you know calibration is complete. Calibration must be completed before each scan. Some stud finders have automatic calibration which makes them easier to use.
You can choose from different settings on your machine depending on what you want the scanner to search for.
Once the machine is calibrated you move it slowly across the wall, keeping it flat against the surface. The LCD screen will then show the presence of whatever you have set the machine to search for. Some scanners will also use an audible alarm to alert you to the presence of live wires no matter which mode you have the scanner set to. Some scanners emit a beeping noise which speeds up as you get closer to a target item.
You should always check the instructions that comes with your stud finder to make you use the tool properly otherwise you may not get safe and accurate results.
Who needs to use a stud finder?
Stud finders and wall scanners are essential tools for anyone completed DIY or refurbishment tasks that require drilling into walls, floor or ceilings or adapting the structure of buildings.
These tools are also vital for anyone working in the building profession to ensure costly and potentially dangerous accidents do not occur.
