A hollow arrow shaft is open at a first end, and is filled in, so that it is solid in the area of its opposite second end for a predetermined part of its length from its second end. Holes are formed through the shaft where such shaft is hollow, next-adjacent the solid part of the shaft. A trail-indicating dye material is provided in the shaft. Feathers are affixed to the shaft extending from the area of the second end thereof where the shaft is solid. A piston member is coaxially movably mounted in the shaft at the first end thereof and extends a predetermined distance out of the fist end and a predetermined distance into the shaft. A head part is mounted on the piston member at the end thereof extending from the first end of the shaft. Thus, when the arrow strikes a target, the impact with the target forces the piston member back into the shaft thereby causing the dye material to gradually drip to the ground via the holes through the shaft to mark the trail of the target.
