Questions & Answers


Can I rent a stud finder?

Asked by Mando May 31, 2020

Hello. Zircon does not have any information on this. We're sure an entry level stud sensor would be cheaper to buy then what it would cost you to rent a stud sensor if you can find one to rent. Thank you.


Asked by Danieloconnell May 15, 2020

Hello Daniel. Yes, that is exactly what they are for. Check the zircon website for more information on how to correctly use the product or contact our tech support through the website. Thank you.

I will be searching for studs behind a shower enclosure made of acrylic reinforced with fiberglas...

Asked by Wayne November 14, 2019

worked on our shower which is ceramic tile over cement board, so figuring thicker than yours

When you put a battery in does it light up or make any noise because I have tried 4 new batteries and nothing happened

Asked by Drablat June 9, 2019

Yes, it acted alive. But it didn't work. You may have the battery in backwards.

Is there a battery and how do I get to it?

Asked by Arnie August 13, 2018

No battery, fell for this trap after I had purchased the product. Worse, there's no way to return it after you have opened it because of the way it's packaged. It requires a 9v battery which is not that common anymore so it's expensive to buy just 1 for use with a stud finder.

I have to agree with most of the reviews. This stud-finder is not worth the hassle or money. It ...

Asked by Rinay March 12, 2018

No! I think this studfinder is a good deal and it works! I found wooden studs and I marked the edges of the studs so that later I could mark the middle with a pencil and hammer in my nail there then confidently hang my heavy wall art.

Are you supposed to keep the on/off button pushed in after calibration and while you’re sliding it along the wall?

Asked by Studdly November 27, 2017

Thing doesnt work avoid it

Does it find wood studs as well as metal studs?

Asked by doc February 6, 2017


Will this locate a metal duct above a finished ceiling?

Asked by Jeremy October 31, 2016

It will but not consistently... You have to run it several times.... sometimes you need to run by an area where you know there is metal duct then it seems to least that was what I had to do when I used it. Also if the duct is not against the ceiling, it wont detect the duct... It has to be almost hitting the finished ceiling. I cannot get it to detect metal duct with thick insulation.

The green light just stays on and doesn't beep or do anything at all. Am I using it correctly?

Asked by Anthony May 1, 2016

Probably. Mine does the same thing. The unit is junk and does not work.

Probably one of the worst tools ive ever purchased. Ill have an opening and know exactly where the stud is and this thing goes right past it. Then it will beep for no good reason and there isnt anything there. Ive tried being extremely gentle, pressing hard, using two fingers. At one point I marked every spot it beeped and I had 8 different markings within a 2’ piece of wall. Going back a forth thinking hey where ever there are more marks is close. Nope! Get a magnet finder. Unfortunately cant even return this. Dont have packaging.

Response from Zircon Customer ServiceSep 3, 2020
Hello Vito. We're very sorry to hear of your experience with the StudSensor HD25. This scanner is a basic model that is only designed for ½” or 5/8” drywall construction. It will only scan down to a ¾” depth. There are materials and construction properties that can certainly interfere with the scanners operation because of their thickness. We would be happy to help you solve the issues you are having with your HD25. Please contact Tech Support through the Zircon website. Thank you. zircon

Works fine
Seems to work fine, our walls are super thin so it detects the studs with ease. Looks like other reviews have a lot of lemons so I would recommend spending the extra $$ if you can. Otherwise, it'll get the job done if you get lucky.

Would beep randomly, beep continuously, or not beep at all with each sweep across the wall. It's not a reliable product and I agree with those who have said HomeDepot shouldn't sell it. It did help me find one stud (ONE!) so it gets one star.

Hello. We’re sorry to hear your experience with the StudSensor HD25. This scanner is a basic model that is only designed for ½” or 5/8” drywall construction. It will only scan down to a ¾” depth.

Solid Product
A great product for the value. It is simple to use and has been very accurate in finding studs in my house. The only complaint is we bought a house out in the country and I did not check to see If it came with batteries, it does not. It takes one nine volt and I had to wait a week to use it until we could get a battery. More on the operator error part on that one though. Again outstanding product, good price, easy to slide, easy to tell where the studs are as there is a red arrow marking the exact location. I would highly recommend this product.

Does the job
If you need a stud finder, this one does the trick with no buttons and whistles. It is what it is. For the price, it is something I needed for future jobs.

This stud finder did not find the edges well. It would only locate one of the two edges per stud after several tries. I had to manually find the studs based on the average distance between each stud should be in a wall.

Hi. What you describe here should not be the case. If the stud is there the sensor should be reacting to it every time. We'd like to help you. There is usually a good reason why these problems occur. We help solve these problems for customer every day. You can call us toll free or email us. We have a 24/7 online knowledge base as well. Thanks.zircon

Not much better than just thumping on the wall!
I think this product was a waste of money. It was not very accurate. I think using my "gut" instinct and thumping on the wall was more useful.
