A whisker marker system has an installation apparatus, a whisker marker, a marker strip, and a whisker fastener. The installation apparatus includes a housing and a driver shaft connected to a power driver for rotating the driver shaft. A slide body coupled to the housing moves between extended and retracted positions. The slide body has a guide channel for receiving a marker strip. The marker strip includes a series of whisker markers, each bunched together with a bunching device and attached to a threaded whisker fastener. In use, the apparatus rotates the whisker fastener until it passes through the bunching device of the whisker marker. The fastener is driven into the ground until it secures the whisker marker to the ground.
