HANMATEK Stud Finder Wall Scanner Detector with Pro Smart Sensor,Audio Alarm and HD LCD Display,5 in 1 Upgrade Wood Exact Mode Stud Finder Tool for The Center Edge of Metal,Studs,AC Wire,Pipe

Love this!! Works better than my 100.00 stud finder. Easy, and accurate!! Very well built. Great value!!

Great Product!

Fast and you don't have to hold a button down like most stud finders. For years every stud finder from Zircon to black and Decker and generics performed poorly. Recently, I used the generic and it could not find any studs in the wall where a mirror was to be mounted. I retested with this one and it found all the studs. ProjectFarm channel tested a similar looking generic and a TackLife brand which also looked the same and It performed near the top only being beaten by a Bosch that cost $260.

Love it

I bought this device to drill my wall house to install some supports furniture, the walls are brick and concrete material and I suppose this scanner might help me to check wires and some water pvc pipes.In the manual indicates that in the wood mode it could detect some materials different to wood, and it is correct the scanner detect some material into the wall, but I am no secure if it is wood, water pipes or wires, so where the scanner generates the alert I am not going to drill there, then until this point this scanner works for me.This scanner works very well detecting magnetic metal, so in that function I am satisfied with its performance.But the big problem with this scanner is in energy wires scan mode ,it does not detect the wires lives easy, when I scan a zone many times, where I know there are wires with 120V, it does not alert. I have tried several calibration process but ever continues whit wrong results. Ironically I have to use the wood scan mode to detect the pvc pipes that contain the wires and in that case the scanner alert me, then I do not drill in that zone.I am not secure if this is a particular problem in my unit or if I am doing the process wrong, although I try to execute like manual indicates. I am located out of the United States, this was an international buy, then the process to return the scanner to Amazon is some difficult, then I will conserve it and when it is possible I am going to buy other device from other brand to complete the detection wires where this scanner fail.

Works.

It can't find anything with any accuracy.

The media could not be loaded. I tested it, but it does not work as smooth as I hoped. A simple test case seems works as expected. Maybe it requires a smooth moving speed. It consumes 26mA when on, should works for 50hours. It consumes less than 1uA current when off, unmeasurable with mA meter, so the battery should last storage life if left in it.
