The PMR 446 two-way radios (private moblie radio - 446 MHz) featured in this section are license-free walkie-talkies for business and personal use (in most countries of the European Union). They work well in survival situations or in the aftermath of a disaster. Typical means of communication (mobile phones, landline telephone and internet) are likely to be disrupted in emergencies. These radios will keep on working. Perfect for emergency preparedness - when the battery packs are exhausted - simply load them with standard AAA batteries.
