摘要： An arrow having an arrowhead assembly attached thereto is provided for marking a remote location with a marking media. The marking media is preferably in the form of a paint ball or a scent ball. The arrowhead assembly includes a media reservoir defining a cavity and a plurality of supports extending outward from the media reservoir along a longitudinal axis. The supports secure the marking media within the cavity in a press-fit connection. In one embodiment, a cap and a resilient nose cone are attached to the media reservoir, surrounding the marking media, to prevent damage to a target upon impacting the target.
