On the last few dives, I've been the one towing a dive flag. It's attached to a hand reel and I find that the line can at times become a possible entanglement issue for me. I switch the reel from time to time in my hands as I go along, which probably doesn't help, but I am always paying attention to it, reeling/unreeling it so the line is not that loose. The dives have been in some busy boat traffic areas, so the flag is definitely necessary. Any tips on how to better handle a dive flag?
