Glad this discussion is happening, albeit seemingly late. I do hope you're able to have a productive discussion in voicing many of the concerns here that people have, spoken and unspoken. I agree with most of what's been said. In looking at the 'cube' dive flag that's proposed, it looks like it could be a nightmare to drag if there's a little wind, one of the drawbacks of even the typical dive flags most use today. I've been at 80ft with a fair amount of scope and a flag getting tugged in the opposite direction of the group, and found myself using a bit more air than the others, and had to pass the flag off to surface early. I can't help but think that would substantially increase with the cube proposed. The issue to me doesn't seem to be the direction of visibility of the flag so much, but the height off the water. I have spotted stranded divers more than a mile away from my boat who became separated from their boat using a safety sausage, and I think the fact that it was off the water 5 or 6 feet was the biggest factor to me seeing them. I think they are lightweight, sturdy and definitely visible. I think at the very least, it deserves to be at least looked at as a very viable 'option'.
I'm not a big fan of politics, but I can't help but notice the owner of the company mentioned in post #24 seems to be the biggest proponent of the cube product, and also seems to be the owner of the website he plugged in his own post (#36), his one and only post to this forum.
I think giving divers multiple options allows us all to be safe, feel safe, and to chose the best equipment that allows us to feel comfortable in the water. I too believe that a BIG piece to this puzzle is boater education. I can't tell you how many people I drive with don't know what the laws are, much less abide by them. Stiffer penalties and programs that help educate boaters would go along way.
All in all I think we're on the right track, and I'm glad to see someone getting some face time with a decision maker. Let's just hope it's more than face time.
Do keep us posted and thanks again for the hard work.
