I used to carry one of those little cans of compressed gas with the
horn
on top in my fishing vest. I figured it would carry a lot further than
hollering.

I'm sure it would. And I suspect it's at least as loud as a
whistle.....probably louder. Also easy to operate. On the minus side;
bulky, expensive, relatively heavy and.....I don't know, how long will one
of those thing go?
