ELECTRONIC MARKER STAKES FOR SPORTS FIELDS
First Claim
1. A method of laying out a boundary of a sports field, comprising:
- placing a first set of marker stakes in a field at first locations corresponding to reference points for a first field sport, wherein the first plurality of marker stakes emit a first signal;
placing a second set of marker stakes in the field at second locations corresponding to reference points for a second field sport, wherein the second plurality of marker stakes emit a second signal; and
locating the first set of marker stakes using a locator which detects the first signal.

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.
