The Best Stud Finder Keeps Getting Better
I've been using Franklin Sensors stud finders for years. I originally purchased the standard version, which served me flawlessly for several years. When the first Pro model with live wire detection was released, I upgraded and used that until I unfortunately misplaced it. After seeing the new ProSensor MAX, I decided to upgrade again, and it's easily the best version they've made. The biggest improvement is the increased number of sensors. Combined with centerline detection, it provides an even clearer picture of exactly where the stud begins, ends, and where the center is. It also retains all of the features that made the previous models so reliable, including no calibration and fast, accurate scanning. Accuracy is where this tool really stands out. I've tried dozens of stud finders over the years, and nothing else has been as consistently reliable. The wide sensor array dramatically reduces false positives and missed studs, even on more challenging surfaces. Being able to see the full width of the stud instead of relying on a single indicator makes it much easier to mark your drilling location with confidence. Speed is another major advantage. Since there's no calibration step, you simply place it on the wall, press the button, and start scanning. The visual display updates instantly, making it quick to trace studs across large sections of drywall, plaster, ceilings, tile, and other surfaces. It saves a surprising amount of time on both small and large projects. Ease of use is excellent. The large LED display is easy to read, the centerline detection removes the guesswork, and the intuitive design makes it accessible whether you're a first-time DIYer or a professional. The Pro MAX is noticeably larger than the previous models, which could be a downside if you're looking for something compact. However, considering the additional sensors packed inside, the larger size is completely understandable and well worth the tradeoff for the added performance. Overall, this is the best stud finder on the market. The combination of outstanding accuracy, fast scanning, and simple operation makes it one of those tools that genuinely reduces frustration and helps you get the job done right the first time. Whether you're mounting TVs, hanging cabinets, installing shelving, or tackling larger remodeling projects, it's well worth the investment.

Get one now, and end your search for a good stud finder!
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.

You want this one.
If you're considering this, just buy it - it's the right stud finder. I, like most people, hated my old zircon studfinder. It was a midrange one with "deep scan" and electrical sensing - it could rarely find studs in my condo walls with double drywall and often "found" non-existent studs or that the entire wall was one giant electrical alert; it was useless. The first time I mounted a TV on my wall, I ended up just opening up the wall to look, which worked but wasn't ideal. After moving into a new place and my girlfriend excitedly buying a new frame TV, I decided something had to change and, probably like you if you're reading this review, spent a LOT of time looking at reviews of studfinders, comparing the M210 to the pro sensor Max, etc. To make a long story short: if you live in a condo, or if you've got plaster walls, or if you're just tired of your stud finder not working, the pro sensor Max is what you want. This thing it's MASSIVE but it's incredible: slap it on the wall and it'll just show you exactly where the stud is, no swiping around, no beeping everywhere. This is especially nice for hanging things which come with templates like TVs; I'll usually mark the studs, position the template, and then do a final check by putting the studfinder on top of the template directly where I plan to drill to confirm - it's a great way to avoid surprises. The switch to go between deepscan and normal is easy to switch while you're on the wall, which is great: I usually start in normal if I'm not sure of the wall, and switch to deep if I'm not getting results. I thought the pencil caddy was a gimmick when I ordered it but it's incredibly useful; no more finding the stud, realizing you don't have a pencil, and then needing to put everything down to grab one. Yes, this thing is 2x as expensive as the competition, but think about what your time and comfort are worth. I've now used this to hang two TVs, including one on plaster/lathe, and it just /works/. Nice when that happens, right? My only gripe is that for the price it should just come with the case - if you're buying this thing, I'd recommend shelling out the extra $20 for a case. A few quick q&As: -Why not just use a $10 magnet or bang on the wall with a fist? Yeah I've got one of those magnets too, and I'll still use it sometimes to double check, but this guy gives a higher level of precision on the actual location so you're not hitting the edge of the stud, can account for warped studs, and frankly, the contractors that built my home were idiots so I don't trust that they actually hit studs with all their screws, plus I assume if a magnet is working fine for you, you wouldn't have made it this far in my review. Re: hitting it with your fist, good luck doing that with double drywall or plaster, hope you like spackling lots of test holes. -How big is it?? It's a chonker. Like seriously this thing is huge. Oh also if you turn it sideways and move it vertically on the wall, you can use it to find blocking - pretty cool right??

It Gets an A
Well worth the price. It took a bit of practice of learning the device but after that, it works great. Had no issues finding stud centers. However, it doesn't distinguish between studs, pipes, or electrical. Also, it's soo good, sometimes it detected obstacles on the other side of the wall, but still not a big issue for me.

Detecting through Drywall - 5 stars ... if it's Plaster, well, read my review ...
I bought this stud detector because it stated that it detected an object through plaster ... the only drawback is, according to the instructions, is that it doesn't differentiate between a stud and a pipe or a stud and wiring. That's a big deal. I don't wanna drill into a pipe thinking that it's a stud ... ... But as far as drywall is concerned, I'd rate it 5 stars. It works great!!! .... But since my house is mostly plaster and I don't know what the object is behind my plaster wall ... I gotta give it 4 stars. I wish they sold one that detected through plaster and let you know if there was wiring/electric/metal behind it.

This instrument works. It is easy to use, accurate and well designed.
This thing works. I have a bad time finding studs. I think the person who put up my dry wall was in some kind of a competition to save on studs or just had spasms of creativity. At any rate they are often not where they should be. For instance rather than put a stud 10 inches from a window where it should have been 16 inches from the next stud, there is a 26 inch space with no stud. With this instrument I was able to figure this out and hang some guitar wall hangers without trouble. The level is also nicely done. It is easy to use, accurate, and just what I needed.

Worth the money
Hands down, this is the most reliable stud finder I've ever used. I haven't tried every one out there, but I've gone through plenty over the years. It's easier to use than anything else I've tried, incredibly accurate, and saves me a ton of time. It just gives you that confidence to get the job done right.

Does not like tile
Cool device and works fantastic on drywallbut it’s very inconsistent when trying to find studs behind tile. Sometimes it finds a stud and sometimes it doesn’t so I wasted a lot of time, drilling holes in my tile. Luckily the vanity hid all the ugly holes.

A BIG stud finder
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!

Bonne efficacité mais ne fonctionne pas derrière du bac acier.
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.

Expensive, but Worth Every Penny
I was hesitant to buy this because of the price, but after using it, I have no regrets. I've used it on a wide variety of wall types and materials, including vinyl siding, plaster, and drywall, and it has consistently found the studs behind them. I've thrown some challenging jobs at it that I didn't expect it to handle, yet it has worked every time. The wide sensing area makes locating studs quick and straightforward, and it's far more reliable than the small traditional stud finders I've used in the past. After using this, I'm never going back. If you do a lot of DIY projects or home renovations, this is an excellent tool and well worth the investment.
