Black and Decker BDL190S Review: If you are in the construction business or do handle a lot of DIY around your home, then you know how irksome it can be to have one tool but not the other. One of the reasons as to why you would want to use a stud finder is to locate the hidden studs behind the plaster and the drywall so that you can customize the room as per your preference and hang the decorations on the wall. By locating the exact position and level of these old studs, you should be able to fix your nails and brackets elsewhere for secure and firm anchoring, so that you can safely use the same without having to wonder your brand new HD TV is going to come crashing down to the floor.

This is exactly the reason that you would want to use a stud finder in your new home, to locate those old studs. But the issue is that these old studs are often located at different depths and a basic stud finder would, at most indicate just the general area where these old studs are located and the general specs. In the end, to gauge it better, you would have to do the levelling yourself which, as stated before, can be quite irksome. And that’s why it makes sense to go in for Black & Decker BDL190S Stud Finder as it comes with the added functionality by including a level sensor along with the product as well as a stud sensor. Sounds interesting, right? So, let’s take a closer look at the same.

Why is levelling important when it comes to a stud finder?

When you use a stud finder to locate the hidden studs in the timber, you would probably need to scan the desired area first. Once you have scanned the desired area, the product in question would indicate the presence of the stud, but so often, you may need to do the levelling on your own to get the location and depth of the stud just right. Thanks to this product, that’s no longer the case, since you can use the auto-levelling interior line laser tool to clearly mark the position of the studs so that you can go ahead and decorate your room accordingly. It is vital that you make sure that you use a good stud finder like this product, as it can indicate the presence of studs hidden behind the plaster, along with wires, metal pipes and much more, well before you attempt any makeover.

Black & Decker BDL190S Stud Finder Review

The Black & Decker BDL190S Stud Finder stands apart from the other stud finders in the market in the sense that it comes built-in with an auto-levelling interior line laser tool. In other words, you get all the functionality that you need, with this particular product – one that allows you to check for studs effectively and a laser liner that can help you do all the levelling you need. This should enable you to precisely locate the studs with ease. Essentially this is a combination tool, one that was specifically designed to change your DIY experience for the better.


As mentioned before, the Black and Decker BDL190S Stud Finder comes with a compact design so much so that you can hold the whole instrument/ tool in the palm of your hand. Its overall design may seem a little bulky at first but that’s mainly on account of the fact that this is a combination tool and contains more than one sensor along with an LED panel to display images and data.


The Black & Decker BDL190S Stud Finder is designed to detect metal, wood, and wire behind the drywall and plaster. In fact, you need to press the button on the side of the product after which it would beep. And around this point, you would need to place the device flush against the surface of the wall and scan the desired area. If the stud finder does locate a stud, it would beep consistently and then, at this point, you would have to use the laser leveller to clearly mark the studs.  The product comes with a great design and one that makes it easy to grip the same and position it against the wall.

This tool is remarkably convenient in the sense that it comes with a laser level sensor as well as a stud sensor. And once it has located the hidden stud you can use the laser to mark the position and the level and plan accordingly. If you were worried about wall decorations crashing down due to hidden studs, you should be able to take care of that issue with this particular product and its laser level sensor. On the downside, it projects the laser light for only about 20 feet and not more. And it also comes with a fan angle of 40 degrees and not more than that. This may seem like that the Black and Decker tool is rather limited but in reality, you are probably only using this for your DIY work at your own residence where each room is not wider than 10-15 feet. Given that, this tool would be perfect for all home front makeovers. It may not be able to project cross beams but on the positive side, it does come with a self-levelling pendulum which should correct the line of sight within moments.

Pros and cons of Black & Decker BDL190S Stud Finder

It is time to review some of the pros and cons of this product.


  • It is a combination tool that includes both a laser level sensor as well as a stud finder sensor
  • It also comes with an LED screen for display
  • It can easily locate all the hidden studs (within certain depth), along with wires, wood, hidden pipes etc
  • It is easy to use and does not come with any convoluted information. It is comparatively easy to use, and you should be able to do so with ease and locate all the hidden studs in the target area.
  • The LED screen immediately alerts you to the presence of studs and wires behind the wall; you would not be required to take any reading or translate it to determine if there is a hidden stud there or not.
  • It comes with easy to use on and off buttons which you can turn on and off when using this particular tool
  • It also comes with attachments at the back with which you can mount the tool to secure it as you use it to determine the presence of hidden studs.


  • One of the first things that we noticed is that it projects only a 20 ft beam which is not that effective if you needed to use the laser leveller in a large room. However, for smaller projects, including your own home, this should be perfect.
  • The other downside is that it can come with some lag time, not much but still, that’s something that the manufacturers of this product need to look into.

The verdict:

Usually, when it comes to stud finders, you often find the tool containing at most one sensor, but this Black & Decker BDL190S  comes with two which should help you locate hidden studs, wires and pipes with ease.  This is effective to the point that you should be able to even locate all the hidden wires, wood and metal pipes that may have been covered by the drywall and plaster.

If you need a handy stud finder for your residence and to fix and hang some decorations securely, then this is the tool that you would need. It comes with an attractive price range that does not put it way beyond your means and is worth every penny. But as a side note, you may also want to check out other customer reviews as that can provide you with more information as to the effectiveness of this product. What makes this combination tool user-friendly is the fact that it comes with a detailed manual so that you would know exactly how to use it, and how to take care of the same. Granted that it projects light for only 20 feet but that being said, it certainly packs in all the functionality you need and more. This is the product that you need to check out, to help make your life easier.
