Abstract
A marker stake for locating a boundary reference point on a sports field can be buried and out of sight when not in use, and then quickly located using an electronic receiver which detects a signal emitted by an electronic marker in the marker stake. Various field boundary indicators can be removably attached to the marker stake. The stake may be embodied in a cylindrical body constructed of a moldable polymer with a socket at one end for receiving a pin or post of the field boundary indicator, and the electronic marker embedded inside the body. The electronic marker may be a passive LC marker tuned to a frequency associated with a known field sport. Different sets of such marker stakes tuned to different frequencies may be used to mark and relocate reference points for multiple sports played on the same field.
