To Whistle

[ref18]

your whistle needs to be reliable, it can't get jammed, like pea whistles often do. Use the pea-less, it sounds clearer, louder, and people stop when you blow that thing. There's no fear of your lips sticking to the plastic on cold days, and it is better for your teeth.

Everyone on a crew should use the same whistle, because it sounds better.

The only problem with the fox 40 is that i've met a few vetren officials who are hard of hearing.
