I work for a council mainly carrying out maintenance to tenants properties.
There are occasions when we need to drill through walls but need to find out exactly where the other side of the hole will be. Obviously a long drill will go through both walls in one go, but as said, there are times we need to be very exact and simply measuring inside/outside etc isn't good enough.
Is there a tool available (possibly sonar/electrical pulse) that can be set on one side of the wall and detected exactly on the other side? Obviously i'm meaning 10" cavity walls and bigger.
