The Biz!
This is the biz! Highly accurate and finds studs under lath and plaster easily too. Made a tricky job a lot easier.

Easy to use and accurate
identifying joist is a nightmare. This usually involves the magnetic stud finder to pick up the nail heads and tapping on the ceiling or walls. However, after using this it’s so easy to find the timbers in the wall and ceilings. Identified the trimming around a staircase being doubled up. Very easy to use and would highly recommend.

Unfortunately, not exactly what was advertised.
Bought it mainly for its deepscaning capabilities as advertised but found out that it doesn't live up to it. It gives very unreliable results, somtimes doesn't find any stud even thou I know it is there, and in this ocasaion it was a thin layer of melamine (4mm) and 15mm pine boards. So not so satisfied with the device. Otherwise, it works great on dry boards when there is one, haven't tested with two on each other. 2,5 out of 5 stars.

Can't find wooden beam under wooden sheets despite it's description claiming it can
Easy to use as it's just a squeeze of the trigger as you hold it, however the thing never once gave an accurate reading when used over plywood despite it claiming to be able to do so. Given it is expensive when compared to other similar tools, for it to not have the ability to function as a stud finder rendered it a poor purchase and so I returned it.

Not for lathe & plaster
Disappointing

This is a big chunky mutha! I had no idea how big this thing was till it arrived. I've had a few other models of their stud finders and they are the best out there. This seems to work even better than the others. Only neg is it will take up a lot of space in the tool bag!

Détecteur qui permet une bien meilleure recherche des montants, dans mon cas des montants bois cachés par un pare-pluie et de l'OSB. J'avais déjà acheté un appareil de cette marque, moins perfectionné (moins de capteurs) mais les résultats étaient très moyens. A noter que si l'on souhaite retrouver les montants bois derrière du bac acier cette fois-ci, ça ne fonctionne pas. L'investissement en vaut la peine.

I love, love, LOVE, my new Franklin stud finder!!! The first box I received had obviously been opened, emptied, and resealed, most likely well before my purchase. However, my customer service experience was easy, fast, and hassle-free. After only one or two short messages to the seller explaining the situation, I quickly received the actual tool the next day. I'm a very amateur carpenter/picture hanger/honey-doer. I have searched for, bought, and tried dozens of different brand, type, model, size, and priced, stud finders in the past 40+ years. You name it, and I've owned and tried it. But in all that time I have never found a single stud finder that I was satisfied with. Not a single one was accurate enough, or consistent enough to ever consider my search for a quality stud finder over with for good. No matter which stud finder I tried, I always had to poke extra holes in the sheetrock to find both edges of the stud, in order to be absolutely sure where the center was located. Most of the things I hang in the garage or inside our house are heavy, and I'd much rather over-build than risk a catastrophic failure and possible injury to someone. So for me, accurately finding the stud's center is critical to installing the lag bolts and heavier screws I normally use. After watching a few videos and reading many reviews I decided to take a chance on the Franklin Sensors ProSensor MAX, despite the steep (for me) price. As soon as my new unit actually came in I took it out to try. I can happily, and with certainty, say that my decades-long stud finder quest has finally come to a successful and very happy end. I long ago reached the point where I dreaded having to hang anything on our walls heavier than an 8"x10" picture, or a calendar. But, no more! You cannot beat this stud finder for quickly and accurately locating wood or metal studs. No way! As fast as you can press a button and steadily slide the unit horizontally across the wall a couple of feet, you can find both edges and center of a stud. I'd say easily within 10-15 seconds. Plus you don't need to poke any extra holes in your sheetrock to double check your tool, not one! The row of bright LED's instantly indicate the whole stud, side to side, and center, with no discernable error of any significance that I could tell. I recall reading some reviews claiming short battery life, but that hasn't been my experience. I've used mine over two months on the initial set of batteries, but I do intend to get the rechargeable battery pack once this first set is done. It's not the beefiest-feeling tool, but feels sturdy enough that I'm not worried about it. With a little care it should last for a lifetime of home use, no problem. I'm so happy with my purchase that I ended up buying a professional-grade padded tool case to keep mine in, for a lot of extra protection and peace of mind. After many uses over a couple of months, I can confidently say that my long search for a stud finder I'm completely happy with is finally over! I'm very happy with the price I paid for a tool that repeatedly, and without fail, operates as easily, quickly, and accurately as is advertised. For me, that's a very rare find. I tell everyone I know and work with about my new Franklin stud finder, and I recommend they get one as soon as possible and end their search, too.

Wow! I’ll never miss a stud again. The first time I used this on old drywall, I immediately understood why it costs about twice as much as most other “good” stud finders. The accuracy is outstanding, it locks onto studs quickly, and it works where others struggle. If you want dependable results, this is the one to get.

Fast shipping and great quality. It really works through OSB and drywall walls. Excellent detection and very accurate. Haven’t used it long enough to determine battery life. This is better than any other brand hands down.
