If you’ve got a PLB, you only need a flare once you can see the helicopter/lifeboat so don’t need it to run for hours or perhaps even minutes. I have not seen an LED flare used in anger but if I had one, I would be interested to see how visible it was on a bright sunny day, the days we like to go sailing. Is it better than smoke?
See post #40 and look at the Sirius video on the website.
On bright sunny days the flash of sunlight on a car windscreen can be seen for miles, ditto heliograph signals.
True knowlege is the product of direct experience.
The US Coastguard are quite conservative in their outlook. If they have approved some, they are likely to be effective.
