Blind Mark is a tool that is designed to align and more accurately install electrical boxes while working with drywall. The set of tools will allow you to determine exactly where exactly the place for the socket is located and it is necessary to drill a hole. The principle of operation is simple - it is based on the interaction of magnetic targets and a locator that determines where the elements hidden under the drywall are located. The set avoids long and complicated calculations and makes the work much easier. The set comes in a handy plastic case. It is very easy to use and even beginners will quickly get to grips with it - the visual instructions on the inside of the case will help to quickly understand the order of work.
