Franklin Sensors ProSensor M150/X990 Stud Finder with Live Wire Detection and 9-Sensors, Wood & Metal Stud Detector/Wall Scanner

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.

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.

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++

Excellent product, hard to believe how much better this is than all the other so-called stud finder I have tried. Expensive, but at least you will not be wasting your money again.

See attached video. I tested this product in a new build with 12.5mm plasterboard with a few mm of skim. I knew where the live wires and studs were. Some studs where metal frame and some 4x2 timber. As a stud finder it worked well, showing the width and edges of the stud with reasonable accuracy - about 3-5mm out at most. This made it easy to determine the centre of the stud. Both timber and metal worked well. Sometimes you get a false signal briefly but just pause and they usually go away then you can move the unit again. My unit did not detect live electric wires however. I tested where I knew there was mains in 2.5mm and 6mm twin and Earth runs. The electricity LEDs never lit up unfortunately despite there being 240V AC present. I did note it was able to detect electricity in open air, i.e. if I placed the unit near a cable without plasterboard between so it seems it was not sensitive enough. There are no calibration controls so this is a problem if you need this function and a safety concern, at least with my unit.

Amazing accuracy and so easy to use no need to dail in well worth it.

I just bought this and tried it for quite a while using new batteries. Didn't find any studs in walls, floors or ceilings. Sent it straight back. (It did seem to find some electrical cables but this isn't what I bought it for)

Great piece of kit. It is very easy to use and takes the guesswork out of finding studs and electrical cables in the walls. The only improvement I would.like to see to make it five out of five would be for it to identify where exactly the cables are, as far as I can tell it shows you that they are there but doesn't pinpoint their exact location. Having said all that Inlove this little de ice and it makes drilling walls much less stressful.
