as suggested in the previous mentioned article in Diver, a diver should be fit enough to run a mile in less than 10 minutes (6.25 min/km).
Ridiculous......
To make a blanket statement that a diver should be able to run a mile in under 10 minutes ignores the huge number of divers who can't yet enjoy a happy, fulfilling hobby with a good safety record.
x a bunch... I think a swimming limitation would be more apt, but to limit diving to those who can run is asininely hilarious.
What about a decent underwater emergency signaling device.
Simply, one touch, close range, wireless, personal, but also transmitting generally, "your buddy having a problem", signal.
Are hand signals or even whistlers enough for you?
Thats a cool idea and wouldn't be all that tough to do with the technology we have from the full face mask coms.
