How To Use A Stud Finder 

By  Enda McLarnon

If you are trying to identify joists, studs and different timbers, or pipes or links behind plasterboard dividers, or in drywall, then you will need a stud finder.

In this article you will discover how to use a stud to discover how to locate joists. We will also look at how to use a stud finder to make sure that you don't hit pipes or electrical cables which of course could be a bit of a disaster.

What Is a Stud Finder?

The name for this product can be slightly misleading. Most people will know what a stud is and the name might suggest that this particular tool is simply an aid to finding where the stud lies behind a covered wall.

That is its main purpose. If for example like in the image to the right, you want to hang a picture, then ideally you need to find the strongest part of the wall. Most walls are made from frames of wood with plasterboard or drywall nailed on top of these wooden frames.

You never want to drive a nail or a screw directly into drywall as it is not that secure and it may also cause the wall to crack. Ideally you want to hammer your nail into the wooden frame that sits behind the drywall. Trying to find these supporting studs is not that easy because they are only 1.5-2" wide and that is why stud finders were made.
Have a look at the video below to see one being used properly.

These can be used when fitting racks, pictures, TV sections, microwave or hanging shelves etc In effect they can be used to hang just about anything that you want, and to make sure that the fixing is secure

Different Types of Stud Finders

Most stud finders work on a comparative guideline. As you can see from the video, they either streak a light, make a sound, or both, when you have discovered the location of the stud. Some of the better ones will also help you locate pipes and wires by changing the setting on the indicator.

In modern houses most plumbing and electrical cabling will be done in a very uniform way. You would not expect a pipe or an electric cable to be running randomly along the back of a stud wall. In older homes, or where a previous owner liked to do things like home projects, then quite honestly you could find just about anything.

Never assume anything and always make the check yourself. It takes a few seconds and can save you from a flood which means a costly plumber's bill. More importantly it can save you from an electric chock, which could actually kill you. The last thing you ever want to do is drill into a wall, or nail into a wall and hit an electric cable.

Read The Instructions Carefully

All stud finders will come with their own set of instructions. Please take the time to read these as each finder has its own method of identification. Most of these instructions will advise you to practice on an area of divider or other surface where you know there to be timber, pipes or links.

The reason behind this is give you the hang of setting the machine and get you used to how it makes its indication. We appreciate that is not always possible to do, but if you can then it is worth the effort.

It also comes with two powerful magnets which allows you to remain hands free.

This one doesn't use lights but it finds the nails in the stud wall and in many ways that is even more accurate than using an electronic one. It also does not need any batteries to work and it will never need any type of adjustment or calibration.

Now there are many other higher technical ones out there, but this one is basic, simple and works like a treat.

We have no hesitation in recommending this one to you. Why spend $30-40 on a fancy electronic one, when for under $10, this will do the job for you every single time.
