Doesnt cost much more than a refurbished unit but comes with a one year warranty

Did the calibration as shown in the manual and sure enough the stud finder did what it was supposed to and found electrical cables within the wall

However as you can see from the images ive attached the instructions are just printed on a folded piece of a4 paper and arent written particularly well

The screen showing the edge of the stud made it much easier to use then the ones with just the red and green lights

It flashes a warning when the sensor picks up live voltage

So far i only used my stud finder once but it gave me the exact location bar none

But did not come with a battery

Took me a few minutes figure out the basics of calibrating it properly before finding the studs but all good after that just took a slow glide across each wall and picked them up every 60cm
