发明名称 Distance marker within a golf course fairway
摘要 A visual distance marker for a golf course fairway and method which provides viewable indicia of distance along the fairway such as from a tee. The device includes an elongated resilient preferably elastomeric or polyurethane marker tube having its lower end slidably or adhesively secured inside a tubular anchor member. When the anchor member is implanted or buried in the ground, the marker tube is supported in an upright orientation extending above the ground, being supported inside the tubular anchor member. The marker tube is sufficiently resilient in all directions so as to be deflected and bent over against the ground as a reel-type lawn mower approaches and passes thereover, thus eliminating the need for removing and replacing the device during normal mowing operations.
