The first style is a simple detection and light system. When a sensor gets a reading, a light brightens. This style is incredibly simple and quite common for stud finders with an array of sensors. This contrasts highly with the second common style, which is a simple LED graphical UI. Think more TI-80 calculator (or worse) than any UI you’ve seen in recent years, but still serviceable enough to give you any required information. A good deep scan mode helps make up for the extra gap created by the texture, but in our tests it was better calibration accuracy that made the biggest difference in eliminating false positives on a popcorn ceiling. How we tested Like all technology, electronic stud finders have seen many improvements from the time they appeared on the construction market in the 1990s. To pinpoint the location of a stud, an electronic stud finder uses sensors that detect a mass behind the wall. They may come with a single sensor, in which case they will detect only the edge of a stud, or they may come with multiple sensors, giving them the ability to detect both edges as well as the center of the stud. Both single sensor and multiple sensor stud finders perform well on average. Sensor Size ACT™ (Auto Correcting Technology) automatically corrects common errors, such as when scanning begins over a stud As the stud finder approaches the edge of a stud, you’ll see an indicator that it detects a change in density. Mark this point with a pencil on a piece of masking tape or a post-it note.
Ergonomics are worth considering, especially if you’ll be using your stud finder on a regular basis. Many stud finders have a comfortable grip in the shape of a computer mouse, which we recommend for users to gently and carefully guide it along the wall. Extra Features Popular Science started writing about technology more than 150 years ago. There was no such thing as “gadget writing” when we published our first issue in 1872, but if there was, our mission to demystify the world of innovation for everyday readers means we would have been all over it. Here in the present, PopSci is fully committed to helping readers navigate the increasingly intimidating array of devices on the market right now. The Studbuddy Plus is a multi-purpose tool that adds a handy level to all the strengths of other magnetic stud finder designs. This is the first magnetic finder we’ve seen that actually gives you more functionality than a set of bare magnets would. If you wanted to mark five or six screw locations and average them out to get a best-possible guess at a precise stud center, the Stud 4 Sure has a small indicator that helps you make more consistent marks than the Studbuddy. The level is too small to be useful for anything other than keeping your marks more-or-less in line with the screw heads you find.Finds stud centers within 1/16th inch, detects metal objects accurately, comprehensive tool yet easy to use Now let's consider in detail the additional convenience feature of the device, which we mentioned above. To get the most out of the free space available in the detector case, the manufacturer decided to build in yet another, quite useful device - a two-direction bulb level. Using the magnets and the level, you can locate metal objects in the wall and mark the horizontals and verticals on which the objects are positioned right away. Thus, the device will be of a great use when you locate in-wall metal profiles because once you get the finder attracted the wall just follow the level and mark the necessary points. SpotLite™ Pointer shines an arrow-shaped light on the wall to clearly indicate the edge of the stud WireWarning ®detection indicates the presence of live, unshielded electrical wiring up to 2 in. (50 mm) deep
Varying visual displays (electronic models only) give you some choice in how you want to “see” the stud. Some electronic stud finders let you preview a digital map of the stud beneath the wall on an LED screen; others feature LED lights across the top that blink when the finder is passed over a stud—both provide a reliable way to pinpoint a stud. SpotLite® Pointer shines an arrow-shaped light on the scanned surface to indicate the center of a stud The Bosch stud finder is self-calibrating. Turn it on, select the mode, and then hold it in place on the wall for a few seconds to calibrate it. During scanning, when the tool neared a stud, an orange light ring on the face lit up. As I slid the device over the stud, the light ring turned red, and the stud finder emitted a beep. When the tool was directly over the stud, the word “Center” appeared on the LCD display.Most, but not all. Some outlets come with boxes that are designed to fit in a hole cut through the drywall. A stud finder that detects both studs and live wires can tell the user if this type of outlet box is in use. Why Trust Bob Vila
To stand out, manufacturers will add features of varying degrees of usefulness. These bonus features can vary from being neigh-on essential (at least, for you) to being expensive price boosters. If you already have one of the best home tool kits, you will likely find yourself not needing too many extras on your stud finder. The Zircon stud finder also did an excellent job of detecting live wires, and while I didn’t have any metal studs to scan for, the stud finder detected steel rebar in a concrete planter. For your convenience, the stud finder handle is made with ergonomic finger indents to fit snugly in your palm. Now, a few words about the scan button positioning. As we mentioned earlier, the manufacturer placed the button on the device left, just where you put your thumb when you take the Zircon e50 in your right hand. Thus, after a short use, you will already be able to start objects detection without even looking at the device. TARGETz™ selectable modes can find the centre of wood studs, edges of wood studs, and centre of wood and metal studs through drywallWhile the T6 won’t give you a precise center line, it always gives a reliable target for your screw or nail.
