Factors to be Kept in Mind while Purchasing the Best Stud Finder for Plaster Walls

No two products are exactly alike. But there are some fundamental elements that should be kept in mind while purchasing a product.

First thing to be considered is the accuracy of a tool. A tool is giving results with how much precision and efficiency is of utmost importance.

There are some factors that one needs to consider while buying a stud finder for walls.

  • Types of Stud Finder - The first thing to check is whether the stud indicator has a magnetic or electronic density detector. Usually, magnetic detector costs less, but it does not have advanced features of detecting hidden wirings and conduits in the walls. However, there are some electronic models as well that are fail to detect studs in lath and plaster walls.
  • Frequent User - The user frequency also matters while purchasing a product. If you are a do-it-yourselfer, then you do not need a stud finder with dozens of high-end additional features for occasional use of hanging shelves and frames. But more seasoned carpenters or contractors need a more reliable and powerful detector. They require a more robust tool which offers additional features. 
  • Display style - Another important factor to be kept in mind is to check which display style provides more useful information according to your needs. You might need a device, magnetic or electronic, with LCD screen which shows density of wall, nearby wiring and piping, and signal power. These features primarily depend on user’s preferences.
  • Pricing - Prices of stud detectors vary depending upon the model and style. The basic magnetic models are less pricey because they only locate stud holders in drywalls instead of finding studs themselves. On the other hand, the high-end electronic models which use sensors to even measure the density of a wall are more expensive. Most electronic models give strong stud-detecting signal indicators that alert you to hidden wirings within the walls.
