Scuba Flag

Diver Down Under Flag used
in the USA and nearby

When S.C.U.B.A. divers go under water they are supposed to deploy a flag as a signal to nearby boats that divers are in the water.

You think there would be no controversy on an agreed symbol to represent that a 'diver is down under,' there is. When you scuba dive in the USA and nearby waters they use the red flag with a white diagonal stripe. But the rest of the world uses the nautical alpha flag. Why can't they agree on just one symbol? Why is there a need for two systems, why won't one side just give up? Why not a third flag of diver down?

diver is down under

I prefer the metric system over old Imperial Empire system that the USA is stuck on, besides it'd goof up football fields. Meters is an elegant and simply superior system. I'm middle of the line with Celsius versus Fahrenheit, I can switch between both systems but Fahrenheit has that nice 0 to 100 degree distance that give us a deeper sense in temperature.

As you can see I'm totally into colour versus color. Many Canadians, Aussies, Brits, and Kiwi's often seethe when us Yanks spell it humor versus humour. It's like the perpetual pop versus soda debate, in the USA.

But when it comes to the diver down flag, the USA has it right. Red is bright and more easily seen than a blue-white flag on a blue and white sky and blue and white ocean!
