Emergency Communication Devices

FAQ — Emergency Communication Devices

What is the difference between a satellite messenger and a PLB?

A Personal Locator Beacon (PLB) sends a one-way distress signal to search-and-rescue authorities with your GPS location. Satellite messengers offer two-way messaging, tracking, and SOS features, plus the ability to send custom messages to contacts. PLBs have no subscription fees, while satellite messengers require a plan.

Do emergency communication devices work everywhere?

Satellite-based devices work virtually anywhere on Earth with a clear view of the sky, including oceans, deserts, and deep wilderness. Two-way radios require line-of-sight and work best in open terrain. Dense forests and deep canyons can reduce satellite signal quality slightly.

How much do satellite messenger subscriptions cost?

Plans typically range from $12 to $65 per month depending on the provider and features. Basic plans cover SOS and limited messaging, while premium plans include unlimited messaging, weather forecasts, and live tracking. Many providers offer seasonal activation for occasional adventurers.

Can I use my smartphone as an emergency communication device?

Newer iPhones and some Android devices offer satellite SOS features, but dedicated emergency communicators remain more reliable with longer battery life, superior GPS accuracy, and guaranteed connectivity. Smartphones should be a backup, not your primary emergency communication tool in remote areas.

How long do batteries last on emergency communication devices?

Most satellite messengers offer 100-400 hours in tracking mode and weeks on standby. PLBs use lithium batteries lasting 5-7 years in standby and 24-48 hours when activated. Two-way radios typically provide 12-24 hours of active use per charge. Always carry spare batteries on extended trips.
