Funny,just looked at the state statutes and they are pretty clearly required.In any case it is SOP for any rational person.
State statutes only apply in state waters. Emerald's shark dives are done outside state waters. I emphasize this point because otherwise it could create the appearance that if Emerald staff don't tow a dive flag, they're doing something illegal. Technicalities matter!
The staff 'group leader' on an Emerald dive, from what I saw, takes chopped fish in a couple of black plastic milk crates down, then feeds sharks, so if you want a dive flag towed the entire dive, I think you would need a 2nd staff person in the water.
It's also noteworthy that on an Emerald dive, at some sites they may be stationary rather than drifting along.
Interesting question; would one of the old Nautilus units with radio functionality, or a similar device, solve this problem?
