Q:can this also be used to locate floor joist
by|Feb 12, 2019
5 Answers
Answer This Question

A:  Yes.

by|Mar 26, 2019

    A:  We used it for wall studs and it works as it should.

    by|Aug 18, 2020

      A:  Yes, Greg. It will detect any variation in density behind just about any normal surface. It just doesn't slide well on a rough surface. But slide it as close to contacting the floor and as steady as you can and it will work.

      by|Apr 16, 2019

        A:  I can t say for sure, but it reads density behind walls so it should do same for floor. Only thing is, walls are sheetrock and floors are thicker, try it . If it doesn't t help you , return it.

        by|Apr 17, 2019

        A:  Hello Greg. The HD35 has a 3/4" maximum scanning depth so it would not be able to scan deep enough for floor joist. We recommend a stud sensor with deep scan like the HD55 or above but please be aware StudSensor™ stud finders can locate joists in your floor, in DeepScan® mode, (scan depth up to 1 1/2") as long as your flooring does not have several layers of material with different levels of density, or materials that are denser than the wood joist that you're trying to find. Materials that interfere with a stud finder's ability to find floor joists include carpet and padding and various types of hardwood flooring. In addition, scanning through floor ceramic tile can produce the same irregular results. It is in these situations that we suggest getting a unit with a metal scanning mode to possibly locate the nail heads to identify the floor joists such as the HD800. Thank you

          Q:Why doesn't this work?

          Answer This Question

          A:  Mine did NOT work with an old but still "good" testing battery; it just stayed green and on without indicating anything under the surface. Then, reloaded with a new battery with a long future expiration year, it found all the studs and projected red arrows on the wall. Bottom line: Get a new, alkaline battery!

                  A:  I have no idea and neither did home depot. When I first bought it, it worked fine. A month later with new battery still didn't work. The brand new trade in stud finder didn't work either with a new battery. Does it need reprogramming?

                    A:  it does work!!!!!

                    by|Feb 7, 2017

                      A:  Be sure you give a couple of seconds to calibrate (read the instructions on the bottom of the device), and then be sure you don't hit any rough spots while you're panning a surface. It's a little sensitive to irregularities, can easily be thrown out of calibration.

                        A:  It works, but I found inconsistent results, so had to repeat the process to get a good response.

                        by|Nov 2, 2022

                          A:  Hi. We’re sorry to hear of your experience with our product. The HD35 is a basic scanner that is only designed to operate on ½” or 5/8” interior drywall construction. All things being equal, it should work great on interior walls as described. Issues with the tool could very well be caused by a low battery. Please replace the battery with a brand new 9V alkaline battery with an extended expiration date of a few years out. Stud finders require adequate voltage to power the sensing mechanism inside the tool. If this does not work, please contact us. We offer toll free support by phone at (800) 245 9265 during normal business hours Mon. thru Fri. 8:00am to 5:00pm PST, as well as email. We also maintain a 24/7 interactive online knowledge base on our web site. Thanks

                            This product is very poor at finding studs, typically just goes in to error mode. I've installed a new battery as suggested and it still fails. It's going in the trash. Ended up destroying a newly finished wall because it wouldnt locate a stud accurately.

                            Hello John. We're sorry your HD35 was giving you false readings. You mention you were scanning on a newly finished wall. Was this wall freshly painted? Painted walls typically take up to two weeks to completely dry depending on temperature and humidity. Until the paint "cures" it retains a certain amount of moisture. This moisture acts like a metal barrier which prevents the tool from calibrating correctly causing it give false readings or to flash constantly. The issue with fresh paint is mentioned in the instructions manual.
                            If this was not the case we would be happy to troubleshoot your HD35 with you and figure out why is not functioning correctly. Please contact our tech support through the Zircon website. Thank you. zircon

                              This is a great tool! Good thing I could not find my old stud finder so I had to buy a new one. This was a huge improvement to my old one, which I found later. I really like the red arrow and the hot electrical wire sensor! I am keeping this one as my primary.

                              The color of product is easy to find. The accuracy locating a stud met my expectations and more. The red locator light is very bright and easy to see. The design of the grip is very comfortable. I would recommend this to others. It's the best stiff locator I've had. I just bought product, however that surpasses two other stud finders I've had in the past,

                              Zircon StudSensor HD35 made mounting my TV wall stand a breeze. I was able to locate not only the studs on the wall I wanted, but avoid electrical lines as well! This device is foolproof and way better than the old fashioned magnetic stud finder.
