About This Product

The MultiScanner HD900 center finding stud finder adds multifunction capabilities to also locate metal and live electricity in addition to studs. Ideal for DIYers and professionals alike, the HD900 makes projects big and small faster and safer. CenterVision technology locates both the center and edges of wood and metal studs in a single pass making projects more efficient while WireWarning Detection alerts you to live, unshielded AC wiring for safety. Switch modes to find ferrous metal, like steel, up to 3 in. deep, and non-ferrous metal, like copper, up to 1½ in. deep. To locate live, unshielded, AC electrical wiring, switch to AC Scan mode. Use to mount shelves, install lighting, or renovate spaces. The HD900 is an all-around tool that earns a spot in anyone's tool box.

Highlights

  • NO FUSS MODE SWITCH: Easily select whether you want to find studs, deep studs, metal, or live electrical wiring with the simple 4-mode selector, achieving many projects and requirements
  • CLEAR AND ACCURATE SCANNING: The bright display, audio alerts, and TARGET SPOTLIGHT indicate target location, while the signal strength indicator helps differentiate between shallow and deep objects for added precision
  • PRECISE MARKING: The SPOTLITE POINTER and illuminated markers clearly show where to drill or cut, improving accuracy and removing guesswork
  • AUTO CORRECT OPERATION: ACT (AUTO CORRECTING TECHNOLOGY) automatically corrects common errors, saving time and reducing frustration
  • Multiple scanning options
  • DEEPER SCANNING CAPABILITY: Scan up to 1½ in. deep with DEEPSCAN MODE, perfect for thicker walls or floors
  • LIVE WIRE DETECTION: Identify live electrical wires up to 2 in. deep to minimize accidents while drilling
  • LOCATE METAL: Detect non-ferrous metal, like copper, up to 1½ in. deep or ferrous metal, like steel, up to 3 in. deep, to find or avoid metallic obstacles during projects and renovations
  • Zircon recommends the use of a brand new 9-Volt battery (sold separately), check the battery expiration date upon battery installation and replace battery periodically due to the LCD power requirements
  • Translucent base and illuminated V-marker groove for more accurate marking of target location
  • Signal strength indicator helps to distinguish between shallow and deep targets

    Locate studs in Stucco walls?
    ByAug 24, 2026
    1 Answer | 
    Answer This Question

    Hello Bcuz - Recommended for interior use only. The wire base in most exterior stucco walls prevents stud finders from operating properly. Regarding interior plaster walls, no two plaster walls are alike. For best interior results, give the MultiScanner HD900 a try over numerous heights on the wall to determine stud location. Then use metal mode to identify the column of nails or screws holding the base material to the studs. Give us a call Toll Free, Monday through Friday, 8am to 5pm, Pacific Time.

        Can it detect wall studs through ceramic tile
        ByDec 9, 2025
        1 Answer | 
        Answer This Question

        Hi Greg - Scanning through ceramic tile can be complicated. The MultiScanner HD900 may help you locate studs in DeepScan mode, or it may help you identify the location of screws in MetalScan mode. After scanning and marking numerous heights on the wall to determine stud location, drill a small test hole through the grout to confirm it. Give us a call Toll Free, Monday through Friday, 8am to 5pm, Pacific Time. Our California Based Technical Support Team is happy to help, and can troubleshoot most user issues in just a few minutes time.

            Zircon MultiScanner HD900 1 Step Multi-Function Wall Scanner will it detect the studs in a bathtub wall through tile
            ByJul 14, 2024
            1 Answer | 
            Answer This Question

            Hello Joseph - Scanning for studs through tile is very tricky and often not successful. There are too many variables. Best to use the HD 900 in Metal Scan mode to try and locate a column of nails or screws holding the plaster board to the wall. After you have mapped a column, use a very small drill bit to confirm stud location by drilling through the grout. If you didn't locate a stud, repairing grout is easier than replacing tile.

              Will this work on cement walls to find conduit
              ByNov 30, 2023
              1 Answer | 
              Answer This Question

              Hi Annie. If it's ferrous metal conduit it will find it up to 3" deep in cement. However, the best Zircon tools for finding metal in concrete are the MT6 and the MT7. They will locate ferrous and nonferrous metal up to 6" deep in concrete and tell you how deep the metal is. For more information please contact our customer support through the Zircon website. Thank you.

                    Hello. We're sorry to hear your HD900 is not functioning properly for you. There are variables in construction that can cause a StudSensor to give false readings and quite often these issues have to do with the environment you’re operating on. There are tried and true techniques we can help you with that can explain why the tool is reacting to density changes that may not be studs and will also promote consistent scanning results. We would be happy to trouble shoot this with you, whatever the problem may be. We stand behind our product. Please contact us through the Zircon website and we’ll figure it out for you. Thank you. zircon

                      what is wrong with this thing?
                      I don't recommend this product. Mine must be defective. It detects a stud when there is no stud, now I have a wall full of holes.

                        This is somewhat of a difficult review. I gave it the 3 star rating because I purchased it for it's Deep Scan option, which did not work at all. If this is your purpose for purchasing this scanner, I highly recommend you do more research. I my case there is 3/4" drywall supported by 3/4" cross supports that the drywall is mounted to. The scanner can find the metal studs all day long. And it is accurate as to their position. But never once coule the scanner find the studs which are 1.5" deep from the surface of the drywall. However, for it's purpose of finding metal and electrical, it worked great. For this purpose, it's an excellent choice and I might have given it a better rating if it had worked for the project I purchased it for. Unforetunately, I have lost a day of work and I have to return the scanner and find something that actually works for the deep scanning.

                        Hello. The 1 1/2" depth is right at the limit of the HD900's ability to scan through and if you add texture you have exceeded the limit even if only slightly. The HD900 has MetalScan mode which can locate ferrous metals up to 3" deep and can be used to find the nails that are holding the cross supports to the studs.
                        You can use DeepScan mode to find the cross supports so you don't mistake the drywall nails for the nails used on the cross supports. Thank you. zircon

                          Great multi-function scanner but as with all scanners - subject to error. I recommend several scans of the same area to be sure you seeing what you suspect is there. I do have to replace the felt slide on the bottom (wall side) of the scanner due to some imperfections causing the scanner to stick to the wall and marking the painted surface. See photos of scanner in use locating metal support post buried within 1" thick drywall soundboard also electrical.

                          This works well for finding studs, but it is advertised to detect pipes and charged wires. It does not. This product did not detect a 1/2" copper pipe that was actually touching the inside of the drywall using stud-find, A/C or deep-scan! Wow!! Also, the electrical detection symbol illuminates whenever it is scanning within about 6" of the actual charged wire. I would NOT recommend this product.
