If you’re looking for a small whistle to attach to your keychain, then check out the Fox 40 Micro. It has a pealess design, which means it won’t freeze or get clogged up. And it’s tiny enough to happily sit on most keychains. And.. it absolutely SCREAMS. I tested mine in the car (dumb move, obviously), and my ears were ringing for the rest of the day. The Fox 40 Micro is also a valuable addition to you child’s backpack or belt. Teach them to blow their whistle three times (distress code) if they’re ever in trouble. If you ever get separated from your child at the mall or supermarket, you’ll easily be able to find them.
