What method of inflation does this Surface Marker use? (oral valve, diver's regulator, other, etc.)
DAVID B Diver's regulator on this one. No oral inflator.
GREG S the bottom edge of the marker is open you can just free flow a reg or your back up reg into it... Overall i have been pleased with it, it is bulky - the entire bag and cord, but its easier deploying using the premeasured 15 ft webbing, then getting out your reel and all that. I would recommend it. However for low risk, everyday diving, I do use a smaller marker. I use this anytime I am doing drift diving.
ROBERT G On this surface marker you must inflate it by the regulator, which only allows it to be a diver below marker, not a diver signal tube. Say you are stranded and trying to get someones attention you can't wave it in the air because it will not stay inflated unless held taught on the surface with some downforce.
