Product Description

Higher Accuracy. Better Technology
The Franklin Sensors Family
Shows FULL WIDTH of studs
LEDs track stud center and edges simultaneously, showing single studs, double studs and irregular configurations other stud finders cannot detect.
More Sensors = More Accuracy
The ProSensor 710+ has 13 accuracy-enhancing sensors. In comparison, other stud finders have only 1-2 sensors.
Deep Scan Always On
One mode finds it all! Franklin Sensors stud finders auto-adjust for different wall's texture, depth and material. Works through interior sheetrock/drywall and more.
Accurate and Easy
Just press and hold the button to start finding studs. No calibration required. Unlike conventional stud finders that give false readings, Franklin Sensors stud finders let you start scanning anywhere, even over a stud.

Frequently Asked Questions
What does the center green light mean?
In certain models, the center LED will turn green to indicate the exact center of the stud.
What does the single blinking light mean?
Several of our models now have a low battery indicator. When the battery voltage is low, the second LED from the right will flash. Replace with two brand new batteries.
Why do the LED lights flash when I first press the button?
In certain models, the LED lights will flash when you first press the button to assure you that the unit is on and receiving power.
What batteries can I use?
For best results, use two brand new AA batteries (check instructions for details).
What materials do your stud finders detect through?
Sheetrock/Drywall
Our stud finders work best through a single layer of sheetrock/drywall.
Lath and Plaster
While many customers have reported success using our stud finders through lath and plaster, detection is not guaranteed due to irregularities in plaster thickness.
Incompatible Surfaces
We do not recommend using our stud finders through stucco, exterior siding, double layers of sheetrock/drywall (common in condos, townhomes and home theaters), tile, wood flooring, carpet or roofing.

- Reviewed in the United Kingdom on 26 May 2025Style Name: Stud FinderVerified PurchaseWorks as it should. Useful piece of kit
- Reviewed in the United Kingdom on 17 January 2025Style Name: Stud FinderVerified PurchaseBeen trying to use a Bosch stud finder at twice the price and getting nowhere so based on reviews decided to give this a try. Popped a couple of AA batteries in a within seconds I had the centre of a stud and confirmed at various points up and down the wall (plasterboard on wooden stud). Double checked with a good old fashioned knock test and good to start drilling holes for a TV wall bracket.
I guess like most of these types of device they will all be prone to error based on the surface/material but got to say that that I'm impressed.
- Reviewed in the United Kingdom on 3 December 2017Style Name: Stud FinderVerified PurchaseGreat bit of kit for finding studs. Just about the best for the price. None of these type of detectors are infallible, but this drvice is quite accurate and consistent. Easy and intuitive to use too. Won't find mains cables, but doesn't claim too. I use this to find lovation & width stud, then use a separate mains cable detector to check for cables before drilling. So far so good.
- Reviewed in the United Kingdom on 9 August 2022Style Name: Stud FinderVerified PurchaseGreat stud finder. Works flawlessly on normal stud walls. It gave some spurious results when using on cement board but normal walls it's 100%
- Reviewed in the United Kingdom on 14 September 2024Style Name: Stud FinderVerified PurchaseUnsure if i trust it. Shows solid lights even when i knoelw theres at best 3 supposed to be on. I'll look at it again, bit so far, i'd be slow to drill where it shows (or not drill as the case may be)
- Reviewed in the United Kingdom on 4 July 2024Style Name: Stud FinderVerified PurchaseBought this for tracing studwork in the ceilings of the house that I am refurbishing. Was a bit sceptical as I have a 'stud finder' that is crap but needed one to save me hours of guestimating where to screw the plasterboard screws in the ceilings that I needed to overboard.
Used this stud finder and it worked saving me hours of work, there were a couple of ghost signals but running it over the ceiling you quickly understood what was what , and with the help of a laser line got the boards up and secure. Well pleased.
- Reviewed in the United Kingdom on 23 July 2019Style Name: Stud FinderVerified PurchaseVery disappointed in this product. Top of the range (so called) and most expensive. I had a better result from the strong magnet to pick up nails. Everywhere it showed a stud there was nothing behind the plasterboard. The product (get out of jail) disclosure on the crib sheet says it cannot be relied on alone to locate studs due to differing materials used in the makeup of the enclosed Wall. Save your money and get a strong magnet as that will at least find the nails. It really isn't worth the money. Most modern Plasterboards and stud walls can have metalised membranes to prevent damp transfer also some soundproofing material can be a factor in giving misleading readings. I now have holes all over my Wall where this tool indicates studs that were not there. Easy to read easy to use but not very accurate I'm afraid. Save your money!

5.0 out of 5 stars Détecteur vraiment indispensable
Style Name: Stud FinderVerified PurchaseC'est un produit utilisé aux états unis (les rois des cloisons en bois placo) Et c'est vraiment excellent pour retrouver les rails de placo pour visser. Comme dit dans un autre commentaire, cet outil m'est devenu indispensable.
Marche aussi avec le bois pour les planchers bois.
En plus fonctionne avec deux piles AA.

- PatrickReviewed in Canada on 27 October 2024
5.0 out of 5 stars No guesswork with this sensor. It just works.
Style Name: Stud FinderVerified PurchaseIt is worth paying a bit more to have a high quality tool. It shows you the width of the trust, if there are multiple, etc... 5 years ago, I bought a high-end DeWalt, but it provides false readings on a problematic wall. This Franklin sensor got it right immediately.
I don't know how long this sensor has been on the market, but I wish I had bought this one 5 years ago.
