This unit + a piece of string = remarkably accurate and dirt-cheap.
This is effective, though it must be stressed that you have to be very sensitive when using this in certain situations.
I was very disappointed the first 10 minutes I tried in vain to use this by sweeping it by hand across various walls. I couldn't detect anything that I was comfortable assuming was a stud nail, let alone drilling a hole in my wall based on that assumption.
HOWEVER: I found it far easier to hang the device with a simple piece of thread and then just swinging it along the wall. Do not touch the finder with your hands at all.
With a string added, it jumped right to the stud nails when I came anywhere close to them. The difference between the two methods is like night and day.
It's a simple way to increase the sensitivity and efficiency of this product.
To anyone disappointed, give it a shot!
