VaBeachmax uses a hook on his belt to drag his when not in the water....A carpenter's hammer pouch works also, it swivels, you slide the scoop handle end in the hole and attach it. Personally if I'm not in the water I drag mine with my free hand to show where I was, so on my return trip I move over enough so that my swing is parallel to the last trip and work a pattern this way in front of high traffic areas, then move down and repeat
