If you are trapped, lost or injured, shouting soon wears out your voice. A whistle carries much further and takes far less effort. Rescuers hear it through rubble, wind and noise.

This whistle has no ball inside. A pea can stick, freeze or swell when wet. A pea-less design works the same in rain, frost or dust. It is loud enough to hear from a long way off in open terrain.

Use a clear signal so people know it is a call for help, not a game. Six blasts a minute is the international distress signal in the mountains. Three blasts is also widely recognised.

Why it’s in the kit

After a building collapse, people are often found because rescuers can hear them. A whistle can keep signalling long after your voice gives out. It weighs almost nothing and costs little.

Storage & maintenance

No maintenance is needed. Attach it to your go-bag or keys so it is always within reach. Rinse it with water if it gets dirty.

How to use it

  1. Keep it on you

    Hang it on its lanyard around your neck or clip it to your bag or jacket zip.

  2. Blow in short blasts

    Short, sharp blasts carry further and use less breath than one long one.

  3. Use the distress signal

    Six blasts in a minute, then a one-minute pause, then repeat. This is the international mountain distress signal.

  4. Keep going

    Repeat the signal until rescuers reply or reach you. Save your voice and energy.
