These are used extensively by photographers at Blue Heron Bridge, a very densely used and totally artificial environment. I have been independently described as having zen grandmaster buoyancy, but I still carry one that had a bolt snap on one side clipped to my harness' right hip D ring, I then tuck the stick behind the webbing and It doesn't dangle or move. Now that I can pivot blindfolded with a 38 lb camera rig held strait out around a seahorse in 4 feet of water without touching the bottom or surface, I dont deploy it as often, but its a great nudi spotting tool.
