Satellite Communicators (also called Satellite Messengers) are similar to traditional PLBs, but with one main point of difference. They allow you to send a distress signal from anywhere in the world like a PLB. However, they also provide the benefit of letting you message friends and family to let them know more mundane news like, ‘we’ve arrived at our campsite’, ‘we’re back at the car’ or ‘I just saw an echidna.’Long story short, as Saphira said, ‘satellite messengers allow you to let people know that you’re NOT in an emergency’. It’s worth noting however that satellite communicators are not necessarily a PLB replacement. Both have different uses and it’s best to do research before deciding which one is right for you.Read more: PLBs and Satellite Messengers – Everything You Need to Know About Off-Grid Safety
