Stud finder reviews | Magnetic, electronic or radar detection?

Best stud finder (electronic and radar)

Stud finders can be used to electronically help you to find studs and other things behind the wall covering that you cannot see with your eyes in the walls.

These gadgets are rather handy and are important tools for carpenters and carpenters and DIY’ers.

Stud finder production began in the 1980s [1], considered a modern device back then, and now thousands of newer, more advanced models now permeate the building sites abroad. 

Stud finders have 2 primary classifications, magnetic and electronic.

Both have the same function but use different processes.

Easy to use with no professional training required, this comprehensive guide will show which ones to seek out. 

To help you locate fixing points inside your walls to help you with jobs from hanging pictures to installing wall brackets such as the long arm tv mount on your wall.

Features to consider when buying a stud finder

• Type. Magnetic types are simpler and more analog but do not have an LCD screen not require much of a power source other than standard replaceable batteries magnetic stud finders have little-to-no electrical components. 
  Electric/Digital ones offer deeper scanning capabilities but are usually more complex and expensive.
• Hands-free. Larger models are usually held constantly against the wall. Lighter models can be affixed to a position while you mark.
• Interface. Your model should have an adequate display, lights, and alarms that make work faster and easier.
• Scanning prowess. This feature determines the depth and accuracy of a model’s scans. Some stud finders can even locate studs in a 3-dimensional plane.
  

Time-efficient. 

A stud finder’s main purpose is to locate studs.

If you want to determine the perfect area on your wall to hang wood art, a painting, or mount a bike, then having a stud finder will help you more easily find studs, saving you valuable time and money in the long run.

Economic. 

With a purpose-specific function, stud finders can last you a long time, given the proper care of course.

Unless stud location is part of your daily work, then you’d normally use these tools in lieu of planned renovations and remodels.

Stud finders are strategic, and are available should the need arise, otherwise, the unit sits perfectly fine in your toolbox when not in use.

1. Identify the need.

For what purpose/s would you need a stud finder?

Before you make a purchase, you have to be clear about how often you’ll be using the tool and for what.

A welcomed addition to being part of your work kit, otherwise, set this as a strategic investment.  

2. Decide on a type.

Would you like an electronic stud finder or a magnetic one?

Magnetic stud finders are simpler and more affordable, ideal for those with budget constraints, who appreciate a tool with a classic feel.

Electronic ones are more functional and ergonomic and are better suited for those who work with interiors.

Magnetic. Stud finders are the OG. As mentioned before, and are simple to use by anyone without complex electrical components.

Utilizing magnets to locate nails/screws and detects the studs, this type requires a little guesswork but is highly convenient.

Electronic. Stud finders are the complete opposite of magnetic ones. These are more accurate and utilize sensors to measure the density of walls in order to find the location of studs.

However, not all work on all wall types as some units can send erroneous readings from some paneling. 

More on radar tech. Stud finders are advanced tools that utilize radio energy pulses to determine a stud’s location.

While radars are more accurate than magnetic stud finders, the tool likewise can detect wires, piping, and most construction elements hidden behind your wall making it a super cool tool to have. 

1. Edge finder. Edge finders work by determining the edge of a stud by measuring the change in density of a wall while running the sensor across a surface. You usually have to run the tool in both directions multiple times to get accurate results.
2. Center finder. Center finders are more accurate and complex and use sensors to scan 2 separate densities of a wall simultaneously to find a stud’s center. You will hear a chime once a stud has been located, or see a LED light.

What can be detected?

• Wooden Studs. Studs are basic support-frame elements for timber-framed houses. As such, they are directly behind your wall linings. Depending on the wall type and structural layout, an ideal scanning depth would be around ¾”.
• Metals. Metal studs have roughly the same optimal scanning depth as wooden ones. The ideal scanning depth would be .5 – 1.5”.
• Live Wires. Wires are often placed safely at the back of the internal structure. The ideal scan depth is at 2”. Note that not all detectors will pick up wires and pipes.

Must-have attributes for electronic and radar stud finders

• Display. Stud finders with screens give more accurate information when compared to just LED ones. Backlit LCD displays are more vivid, allowing you to get clearer, more precise readings.
• Multiple Scan Modes. Versatility is always good. Having multiple scanning modes gives you more options; from light, scans to get initial readings, to deeper ones that can detect and indicate the possible location of pipes and other hidden elements.
• Warning Indicators. Appropriate prompts will alert you about live wires and plumbing. This is more of a safety feature and mitigates the risk of potentially damaging important attributes housed behind the wall.

If you want the best stud finder and one that’s more advanced, then consider the Bosch D-Tect150 as the pinnacle of detection.

With precision-laser technology and 7 specialized scanning modes, you get superior performance even up to 6” deep into dense spaces, including concrete and floors, regardless of whether walls are dry or not.

Readings are clear and easily viewed thanks to their bright and colored display.

You need to not worry about making constant adjustments because this model is self-calibrating – and automatically makes the necessary adjustments to stay on track at the start of the detection process. 

I like that this is highly versatile, and runs on 4 AA batteries, and practically runs itself, what more do you need? X-ray vision?

Best in value goes to the Zircon MulitScanner A200 for the commendable mix of capability and price.

This Zircon stud sensor scans up to depths of 3”, including metal, and detects both studs and other hidden wall elements with the help of 4 flexible scanning modes. 

Get clear and accurate readings with the aid of the patented Spotlite and auto-correcting technology of this Zircon stud finder.

View clear results on the ultra-bright LCD and stay safer with a wire-detection feature.  

The Tavool TH250 is the most budget-friendly electronic stud finder you can get.

While price is friendly, the unit doesn’t lack any of the important attributes and still delivers an acceptable performance.

You get 4 modes, including deep detection, Live AC wire detection up to 2.36”, and even a limited amount of self-calibration! 

While this might not give a stellar performance, the Tavool stud finder will certainly serve the purpose well enough while maintaining a professional look. 

When DIY comes to scanning with sensors only, nothing beats the Franklin Sensors ProSensor MAX.

The Franklin is all about coverage area and multi-sense technology, along with 13 sensors, enabling the stud finder to cover multiple locations simultaneously. 

With two modes of easy operation, it can scan walls of different types, including plaster, tiles, MDF, a layer of sheetrock, and even two layers of drywall.

You may not get a screen, but the tool does make up for that with multiple bright LEDs for simplicity, while being impeccable in portability.

I use this simply for the simplicity on offer, while I find the lights easy to visualize when checking for hidden wall studs.

Stationary magnets.

Mostly common magnets that react via magnetic force as the tool come across metals near the surface of a wall.

These are not effective on walls made of plaster as studs are placed further back

Moving magnets.

Magnetic stud finders use neodymium, a rare earth metal, that oscillates and makes a buzzing sound when detecting dense material.

Neodymium owns the strongest magnetic pull and can detect even deep-fitted studs.

Always do this.

• Know the wall type; magnetic stud finders tend to be more effective on plaster, while electronic ones are better with drywall. 
• Always check the power level of models that use batteries. Not having enough charge can often lead to erroneous readings.
• Properly mark spots with removable material such as lead pencils or a piece of tape. Always double-check to avoid false positives before marking.
• Make sure to have a decent spot to store in your stud finder in. If you haven’t got one, here’s a list of tool backpack that electricians must-have.

Watch out.

• Always remove any obstruction relative to the area you aim to work on, regardless of how proximal any rubbish or junk is to your chosen starting point.
• Don’t mark the wall with tacks or any permanent marker if you don’t need to.

 If you need a stud finder, then the best option would be the Zircon MulitScanner A200.

This model is decently priced and you get all the neat attributes that you would need in order to work accurately and efficiently.

An alternative to the Zircon is the Franklin 710 Prosensor.

It may not have a display, but the multiple sensors and included magnetic stud finder helps you cover more ground and work at a faster pace.

The Tavool TH250 is your go-to if you’re working on a tight budget and want an ideal tool for occasional and casual use while maintaining all the necessary components.

If you want to take stud detection to the limit, then look no further than the Bosch D-Tect150.

This Bosch stud finder is a powerhouse of a tool that is advanced and offers superior scanning through almost any material. The only drawback would be the ludicrous price tag. 

Stud finders are convenient and are constantly being developed, and so is your tool repertoire and knowledge.
