# How to signal so a stranger can find you

> Three blasts, a pause, then three more. So that pattern is widely taught. A private family code does not help the person who does not know it.

Part of the [Comms](https://bordernest.com/silo/comms.md) guides.

A whistle on a zipper beats a whistle in the bottom of a bag. So blow three times, wait, blow three more, and keep that rhythm if you want a stranger or a searcher to notice. Tell the house the same pattern so you are not inventing a new one under stress. The Fox 40 we list is pealess, and the Amazon page says there is no little ball inside. It still only works if it is in your hand, which is why the do this today action is simple: clip it to a jacket zipper or your key ring tonight, then blow it once so you know how hard you have to push the air.


## Why three of three

Search and rescue teams train on the universal distress signal of three short blasts, a pause, then three more, and the pattern is taught because strangers recognize it without a code book. A private family whistle pattern is fine for the backyard, but the rescuer who walks into your neighborhood does not know your family code. Repeating the pattern over and over is what carries the sound past wind and traffic, and it is what tells the listener that this is intentional, not a kid playing. Keep the rhythm steady, rest when you have to, and start again.


## What to look for in a whistle

A real signaling whistle has no pea inside, because a pea can swell, stick, or freeze and the whistle goes silent right when you need it. Hard plastic or metal is fine, and a lanyard slot or a built in clip is what keeps it on you. Loudness matters less than reach, and reach comes from repetition.

## When a whistle is not enough

If you are trying to reach the other person in your own parking lot, the radios are the tool, and the mile number on the box is advertising. So that writeup is two radios for the people in your house, and the room overview is hear the warning, then be able to find each other. A whistle calls a stranger you cannot see, while a radio calls a specific person you already know is close. Both belong in the kit, and they cover different jobs.


## Bridging to the next guide

A whistle gets attention from a distance, and a radio passes a message across a parking lot, but neither one helps if the warning never reached you in the first place. The next guide walks through the alert step, which is the part that has to fire before any of this signaling matters.
