>>1498068Two different devices, some overlapping functionality.
If you don't need/want the additional features of the communicator (text-messaging, OK-messaging, tracking, help-but-not-911), then I'd recommend a PLB.
PLB = EPIRB = ELT. Difference is how they're deployed/activated; they all use the same system when activated.
PLB tx's on an internationally-protected frequency for life safety, at a much higher power than a communicator does.
Communicators share spectrum with satphones, telemetry devices, etc.
On "911" activation of a communicator, the process your provider follows is similar to what AFRCC does. Pulls up your profile/registration, tries calling your numbers to see if it's accidental, tries calling emergency contacts, then deploys local resources with that information.
PLB is a sealed battery, mine's 5-year maintenance. Costs about $100 to have the factory service it.
Communicators run on readily available batteries, and with moderate daily use will go a week or two. (Just doing a few check-ins/OK-messages a day, a set of AAA's will last well over a month.)
I carry a PLB. Most guys I ride with carry some sort of communicator. Of the two (SPOT vs. InReach), i'd recommend InReach. Every now and then I ride with someone who carries a satphone.
