I can tell you for sure, that the simplest 4-finger whistle method will outperform any small plastic whistle, being of 0 oz in weight and 0x0x0" in dimensions...

Any thoughts?


Doesn't work when your missing one of your hands or they're are so cold you don't want to take your gloves off. The nice thing about a whistle is it doesn't require your hands, so you can still signal even when your hands are frost-bitten and you're too tired and beaten up to yell.
