Both the Garrett Pro-Pointer AT and Garrett Pro-Pointer II excel at locating metal studs and nails hidden behind drywall. These pinpointers detect the metal components in wall framing with precision that often surpasses dedicated stud finders.
Why Pinpointers Work Better Than Traditional Stud Finders
Standard stud finders rely on density changes or capacitance detection, which can give false readings on textured walls or near electrical wiring. The Pro-Pointer AT and Pro-Pointer II detect actual metal - the nails, screws, or metal studs themselves.
This metal detection approach eliminates the guesswork. You're not hunting for the stud's edge - you're pinpointing the exact location of the fasteners holding your drywall to the framing.
Technique for Detecting Wall Studs
Start by running your Garrett pinpointer horizontally across the wall at about chest height. You'll hear distinct audio signals when the tip passes over drywall screws or nails. Mark each detection point with a pencil.
Most drywall fasteners are spaced every 16 or 24 inches along the stud, so once you find one screw, move vertically to locate others on the same stud. This confirms you've found the stud centerline, not just a random nail.
The Pro-Pointer AT's waterproof design means you can use it in basements or other damp areas without concern. The Pro-Pointer II offers excellent sensitivity for this application, though it's not waterproof like its AT counterpart.
Comparing Pro-Pointer Models for Stud Detection
Both models perform exceptionally well for stud detection, but there are subtle differences. The Garrett Pro-Pointer II provides slightly more aggressive audio feedback, which some users prefer for wall work.
The Garrett Pro-Pointer AT includes additional features like multiple sensitivity levels and LED lighting that can help in dim crawl spaces or attics. For purely wall-based stud detection, either model works brilliantly.
Tips for Accurate Results
Keep the pinpointer perpendicular to the wall surface. Angling it can reduce sensitivity and give inconsistent readings. Move slowly - quick sweeps might miss smaller fasteners.
If you're getting signals everywhere, you might be dealing with metal mesh behind plaster walls or metal conduit. In these cases, look for stronger, more consistent signals that indicate structural fasteners rather than background metal.
For metal studs, you'll get broader detection zones since the entire stud is metal. Wood studs show up as distinct points where the drywall screws attach.
Beyond Basic Stud Detection
These same techniques work for locating ceiling joists, finding pipes behind walls, or checking if an outlet box is properly secured to framing. The versatility makes either Garrett pinpointer a valuable addition to any toolbox.
Professional contractors often prefer this method because it's faster than traditional stud finders and works reliably on various wall textures and materials.
Whether you choose the waterproof Pro-Pointer AT or the classic Pro-Pointer II, you're getting detection capabilities that extend far beyond treasure hunting into practical home improvement applications.
