Much better than other stud finders
I’ve tried a few stud finders before and this one is much better and far more accurate. It detects the full width of the stud rather than just the edges, which makes it much easier to see exactly where to drill. Very simple to use with no complicated calibration, just place it on the wall and move it across. The display lights up clearly when a stud is detected. Overall a very reliable tool and a big upgrade over cheaper stud sensors.

A Game Changer for Stud Detection
Using this is a whole new ball game in detecting studs; it's just so much easier than the traditional single-sensor stud detection machines. Electricity wire detection is not quite so accurate; it'll detect the current but trying to pinpoint its exact location is extremely hard. However, you know to avoid the area! The only real downside with unit is not related to its operation but its price. At £38 is very expensive compared to other stud detectors, however as mentioned, it does have a rather unique operation so maybe that' explains the high price.

Detected power no problem.
Used this to avoid power cables when putting shelves up in she’d. Power cables are running through the walls. Works well.

Identifies location of most live wires reasonably well but I wouldnt rely on it
Not a great device. Identifies location of most live wires reasonably well but I wouldnt rely on it. Within its limitations ease of use and value for money are ok

Stud finder very accurate
Absolutely the best bit of kit I’ve bought in the last 12 months. The ability to find the center of a stud is a game changer for me. I love how it lights up green when the center is found, goes that extra bit of confidence. The electrical sensor works great too, but hard to know where exactly the electrical wire is, the sensor just lights up a yellow led shaped like lightning. I am presuming it’s the center of the device it is alerting for. Either way, it’s the best sensor I’ve owned. A++

Good for stud finding, but not good for cables
Good at stud detection, not so great at cable and electricity detection. It is easy to use and is light, though I am not sure it would survive many drops.

Quality Baten Finder...... And then some.
I have tried many Baten finders, most are unreliable, the rest are just gimmicks, that just don't work. Cheap or expensive it's very hard to find one that's "The real deal" I needed one for a job, so I thought I would try this. The Franklin Industries ProSensor X990. Well, I must say, I was very impressed. Every reading I tried was bang on. No false readings just accurate readings every time. It also finds power cables behind plaster boards and 2 ⚡ symbols illuminate yellow when found. One thing I thought was cool is, when the red leads find a Baten, it's center led turns green to indicate center of Baten. And......... it's very very accurate. Great product, for a reasonable price. They do have higher priced models but, this was fine for what I needed. Highly recommended.

Amazing!
I recently moved and had loads of things to hang on the walls- cabinets, shelves, etc., all of which required a good ‘hit’ on a stud. I invested in the Franklin stud finder to update my lifelong Amish “knocking on the wall” method. I am happy to report that it works great! It has been 100% accurate in finding stud centers, and warning me when electric is nearby. It is very intuitive to use and saved me time and wall damage. I am a 76 year old man and I wish that I had one of these sooner. Highly recommended!
