Excellent stud finder
Reviewed in Australia on 29 July 2020
This is a brilliant stud finder.
Two small negatives are that the spirit level on my unit is not accurate and that it has inch measurements on top. No one measures in inches except apparently the US. Personally I don't care about these issues because I have other devices for levels and length. My suggestion to the manufacturer is to remove the spirit level and inch measurement and then you have a brilliant device that is suitable for the rest of the world - which is metric.
This device's method of stud finding is simply excellent. There is no calibration (it does that based on the average of what it reads across the sensors). You press the button, hold it to the wall - and it just works.
So my advice is:
Ignore the spirit level.
Ignore the inch measurements on top.
Just buy it.
