七合一安全哨子，探險精神

The built-in whistle is loud enough to cut through wind on a ridge trail, and I love that the fire starter and signal mirror are all packed into one clip that weighs nothing on my pack. Used it twice on a weekend hike and already feel safer solo.

The compass on this thing is surprisingly accurate for such a small gadget. I’ve already used the fire starter on a camping trip and it worked on the first try.

I was a bit skeptical about a whistle having seven functions, but the built-in compass and thermometer have already come in handy on two hikes. It clips securely to my backpack loop and doesn’t add any noticeable weight.
