The Slim Rescue Howler™ weighs only a few grams but it packs a big punch: namely, a 100dB signal that is audible from over a mile away. The pea-less design means this whistle works in all conditions and will never jam or freeze.
- Be Heard: 100dB whistle signal is audible over one mile
- Fail-safe: Pea-less design works in all conditions, won't freeze or stick to lips when cold
