Abstract: A novel insert assembly for use in snowboards and other sporting equipment provides for embedded insert location, regardless of the properties of the insert material per se, and without requiring either expensive equipment or a complex location process. This is achieved by positioning a small inexpensive magnet on or within the insert cavity, or placing a plug-like magnet in the open threaded end of the inserts. After the board assembly is complete, a magnetic material such as iron powder is dusted on the surface of the board to react with the field lines created about each insert, revealing the insert location. Then, the board can be drilled to pierce the insert cap, and facilitate removal of any plug in the insert. It is also possible to provide, through powdered metal technology, an insert material which itself will produce the desired magnetic field of sufficient intensity at the dusted surface of the board.
