![]() ![]() These, as the name suggests, incorporate an array of sensors. A third, and relatively recent introduction is the multi-sensor stud finder, also called an instant stud finder.Center finders have multiple sensors, so they can gauge the full width, and indicate the center for you.You can then mark the center of that stud. It cannot tell you the size of the stud, so it's a good idea to make a mark, then approach from the other side, to make sure you know the width. In general, an edge finder has a single sensor that detects a change as it occurs - the edge of a stud.Results are displayed on an LCD screen, which gives a quick and clear indication of what's going on.Įlectronic stud finders are further broken down into different types: Unlike magnetic stud finders, they're not reliant on magnetism at all, so they find both wood and galvanized steel studs equally well. Most need to be placed against a wall for calibration (an area where there is no stud), then as they are moved along the surface they measure the wall and feedback data until a different density is found. Using one or more sensors, they measure changes in the density of the wall (technically, the dielectric constant). These come in a variety of forms, but all work on the same basic principle. They're also attracted to any ferrous metal, so it could be a drywall screw – but it might also be steel tube, rebar, or who knows what hiding in the wall. There's no way to know if the fixing is off center. The main drawback with a magnetic stud detector is that they locate the fixing, not the stud. A bubble level might also be incorporated. Often the stud finder incorporates a central groove, or "V," to help you position a nail or screw, or make a pencil mark. Some are molded into a durable plastic casing, others are left loose. With a fixed magnet, you just push it across the wall until you can feel magnetic attraction. With a loose magnet, you get either an audible "thunk" as the magnet is attracted to the fixing, or there's a visual indicator - generally, a bright piece of plastic will pop up. Not surprisingly, there are some pretty strong magnets involved. If your magnetic stud finder sticks to the wall, there’s a good chance there’s a stud there! These use a very simple concept: the nails that hold studs together are magnetic, and so are drywall fixings. There are two main types of stud finder, magnetic and electronic. Zircon held exclusive world-wide manufacturing rights until 1998. The capacitor-based electronic stud finder was invented and patented by Robert Franklin in 1977. If you'd like more detail on how stud finders work, and answers to many of the questions that crop up, please read the following report. They cover just about all the possible choices, so they offer performance and value to suit every user. The stud finders in the product list above are those we recommend.

The right tool can find those studs in seconds.īut which is the right tool? Old-school magnetics or modern electronics? BestReviews is here to help. No more hit and miss with a hammer or a knuckle.

I would recommend this tool to be part of everyone’s tool chest since it is very versatile, small and an invaluable tool. ![]() Another uniqueness of the StudBuddy is you can always find it in your tool chest or anything magnetic so it will not get lost in the bottom of your tool chest like so many other tools, you simply attach it to a magnetic item and voila you will always find this tool when you need it! My StudBuddy has easily become an essential tool for hanging anything heavy requiring a stud. The StudBuddy can only be used on drywall not on lath or plaster walls is the only downside that I see. The stud lies behind the drywall at all points above and below the StudBuddy! The StudBuddy requires no batteries and you can easily hang shelves, televisions, racks, hooks, etc. When Studbuddy sticks to the wall a nail or screw has been detected in the stud. You simply place StudBuddy against the wall in a vertical position and slowly scan your wall back and forth in 24 inch sections while gradually moving up and down the wall. ![]() The StudBuddy is quite simply the world’s easiest stud finder! This small but powerful magnetic stud Finder works with all drywall construction.
