Best Off-Grid Communication & Signalling
When mobile signal drops or a group needs to split up and stay in contact, phones aren't enough — a dedicated way to talk and a backup way to be found matter just as much as anything else in a kit.
We've picked a pair of long-range walkie-talkies for staying in contact across a campsite, hillside or during a power outage, a pealess whistle that carries much further than shouting, and a glow stick for marking your position after dark without needing a working battery.
Item entry
Two-Way Radios
When phone networks are down or you're out of signal, two-way radios keep your group in contact. Essential for coordinating a family, a hiking party, or neighbours during an outage.
Features to look for
Genuine usable range
Advertised ranges assume perfect line-of-sight. In towns and woodland real range is much shorter, so favour proven models and test them where you'll actually use them.
Rechargeable with AA backup
Rechargeable packs are convenient day to day, but models that also accept AA batteries let you keep going when there's no power to recharge.
Licence-free PMR446 channels
In the UK, PMR446 radios need no licence and are legal to use out of the box. Check the set is PMR446 for hassle-free, legal operation.
Common mistakes
Trusting the box's range claim
A '10km range' radio may manage a few hundred metres in a built-up area. Test realistic range before you rely on it for safety.
Not agreeing a channel
In an emergency there's no time to fumble settings. Agree a channel and sub-code in advance and write it inside the case.
